Home Theater Acoustics – Listen to Your Speakers, Not Your Room

Home Theater Acoustics – Listen to Your Speakers, Not Your Room

Once you take a decision to make an investment on some type of home theater gear, the next thing you will probably be doing is to make a visit to the home theater showroom and you are simply impressed by the high end system and buy it at an exorbitant price and take it home. You are full of excitement, spending a lot of time fixing and installing it and finally when you actually slide in your preferred DVD, you find that you are not getting the same smooth and thrilling audio experience you felt when it was played for you at the shop. So what went wrong?

The main thing to be noted is that once the AV system delivers reasonable quality of sound, the possible reason for unsatisfactory audio could be the room acoustics, which is the most ignored aspect in setting up your home theater. When the listener is at some distance from the speakers, what he hears is what is known as “far field”, as the sound is in fact coming to him indirectly from the surfaces of room and not from the speakers. The speakers disperse the sound in all directions, and the room gives the effect of a big filter, amplifying some sounds while moderating others.

How to go about this task? If you can afford it, better hire a consultant who is an acoustically qualified professional and it will be worth your investment.  If cost must be kept down, you sure can improve the room acoustics, just by following some simple rules.

  • If it is within your capacity, tackle excessive external noise, (HVAC, footsteps, traffic etc.).
  • You wall area to the extent of 20-40 percent must be covered with acoustical absorption panels in order to lessen reverberation, echoes and flutter.
  • Install absorptive bass traps in corners for minimizing building up low frequency sounds.

There are several products for noise control available for keeping undesired sounds from getting into your home theater. Duct silencers and duct and pipe lagging can minimize HVAC noise, isolation clips and vinyl noise barrier can decouple ceilings and walls thus interrupting the transmission of sound wave, and acoustic doors with door seals can also help. The purpose of these is to increase speech intelligibility in the soundtrack of the movie by reducing the signal/noise ratio. Bass traps and acoustic panels are available in different materials and prices. Panels wrapped with custom fabrics can be made to match the room’s decor, so also prefabricated panels and ready-made kits. The bottom line is that an average sound system in an acoustically treated room will perform better than an expensive sound system in a badly tuned room.



How to Build a Recording Studio – Part 6: Separate Rooms: Control Room and Live Room

How to Build a Recording Studio – Part 6: Separate Rooms: Control Room and Live Room

Control Room

Almost all studios have many isolated rooms for recording, mixing, as well as production. The principal agenda when building multiple rooms for a studio is soundproofing. To realize this, the foremost objective is making the rooms airtight. If you can prevent air from leaking in or leaving a room, sound also has less chances of entering or exiting.

Usually all pro studios use double doors fitted with sound lock to prevent leakage of noise. They are also built with thick dual walls having air gaps in between them to help trap undesired sound. The studio floors are also floated meaning that they are raised above the ground level to further prevent more leakage and vibrations.

The first area of focus is the Control Room which houses the mixing console and outboard gear. Control of all the recording and mixing is done here. The acoustics of this room is so designed that we can hear the exact sound being recorded or mixed. The sound in the room should be such that it represents the sound as natural and accurate as possible.

The foremost condition for a room that is acoustically treated properly is that there are no parallel walls. Suppose you are inside the room having solid parallel walls, now clap your hands and you will hear the sound reflecting to and fro. This is flutter echo. This is undesirable for recording as well as for mixing. For the sound to be great, you have to trap the undesired bass in the room also. It is estimated that twenty five percent space in a room should be set aside for bass traps for proper mixing room.

Live Room

The next location commanding equal importance is the Live Room. The music is recorded here where the vocalists and musicians perform using the microphones. Since they are required to adapt to varying recording situations live rooms have to be more versatile. Wood floors are examples of great reflectors of sound, creating a brighter tone. If you need a warmer tone, you could just lay a rug on the floor. A number of live rooms are fitted with a considerable amount of glass to enable sighting between rooms for better communication besides being very reflective. Several studios also use curtains to regulate the quantity of reflections off hard walls or glass. Non-parallel walls are essential to remove flutter echoes.

A few studios also have a vocal booth inside the live room. This a smaller room meant for vocals. They are also usable for guitar amps and some instruments. No specific rules are laid down for its utility; its main objective is additional isolation when the recording process is on. Glass windows and doors are used so that the artists and people operating the control room can see each other.

Many high end studios may have more than one control room and production set. Lounges and good bathroom facilities are also critical in maintaining creativity. It can also have a kitchen and dining area if budgets permit. People work for several hours in the studio on projects. It is imperative to provide them all the domestic comforts so that everyone is happy.

You also need comfortable offices with private internet access for the client to handle his business without any interruptions. Every studio has a different design limited only by your imagination. There are only guidelines, no rules.

Ceiling Panels Can Add Beauty and Elegance to Any Room

Ceiling Panels Can Add Beauty and Elegance to Any Room


Based on the style of home you are functioning in your option of ceiling panels will differ. You can opt to go with a tin ceiling panel which can be hung from the ceiling like a typical acoustical panel or also a fiberglass one that is stuck straight to the surface of the ceiling. Regardless of what sort of ceiling panels you choose you can save plenty of money by installing them yourself.


When considering installing light ceiling panels, or panel of any other type, you must follow a few easy rules to make sure that the project emerges as well as you would like it to. You will foremost have to decide the precise tiles that you need. Even though most tiles are sufficiently similar to install there are a few having their own unique considerations. Ensure to read the suggestions of manufacturers and ensure that they will be working for your specific application before investing the money and time in bringing the entire shipment home.


The subsequent thing to do is find out exactly the way you will be applying the panels. Few panels can be installed in many ways and others should be installed in only one or two precise ways. It doesn’t matter as long as the method of installation will work in your particular space. Suppose you discover that the panel you would like should be installed utilizing a method that you are either not comfortable doing or won’t function in your house and then you could have to make a different selection. This though is an improbable prospect presently because of the huge number of styles and designs in the market.


It is not probable that the working of your room will be perfect with precise full tiles. Because of this reason you should choose the dimension of the border panels. Suppose at the start of the space you begin with full tiles subsequently by the time you reach the other side you could very well finish up with a tiny slice of panel. This way is not preferred since it looks very unprofessional and unfinished. Because the objective is to appear professional, neat and clean you should make an effort and plan out the precise size of each and every cut panel in the space before starting work.


After doing all the planning, the installation is an easy task. Always follow the suggested installation instructions of the manufacturer. This is an excellent thing to do for many reasons; though the major two are the manufacturer’s warranty and final product appearance. The appearance is very self-explanatory and simple. But the warranty is not the same. Suppose you do not utilize the proper techniques or materials then the manufacturer can opt not to guarantee your ceiling panels, which implies that at your own danger you are installing. Plan things prior to doing them and you’ll be pleased with your ultimate product. Most significantly of all, be secure while you work.

About Wireless Home Theater Speakers

About Wireless Home Theater Speakers

Setting up a surround sound system presents several issues to the users, the worst of them being handling to cope up with the numerous wires used for connecting it to the speakers. It is the wires that are short at times, or may be that they are not sufficiently powerful. Sometimes it becomes a nightmarish job to manage the wires around the room which can be more tedious than actually mounting all the speakers. Fortunately, several manufacturers have realized this bottleneck when you are setting up a home theater system and they have devised the wireless home theater speakers to overcome this frequent problem.

No hanging wires

Wireless speakers are made such that they provide the crisp and clear sound experience like in a movie theater without all the difficulty. These speakers not only avoid all the trouble associated with drawing the wires around all the furniture in the room and the walls, they are also helpful in making the room with speakers look much better. Your room will have a cluttered look with all the wires hanging from the speakers. Without the wires your room will look as though you had installed the speakers professionally and more expensive than they really are. Actually, it may be surprising that that often these speakers are less expensive than the conventional speaker systems for home theater.

The technique

But, one may wonder how all this works. Wireless speakers are wired internally almost like in the case of remote controlled cars. Conventionally, speaker systems for home theater used to be designed with multiple speakers linked to all the devices in the home theater via an amplifier. To make the process simple, wireless speakers function through a receiver and transmitter system. All the devices are made with their own built-in receiver and transmitter. The sound signal then gets dispatched through the room to associated devices, creating the home theater experience devoid of all wires.

This modern technology has made the wireless home theater speakers astonishingly cheaper than wired ones and at the time offering great sound quality. The only difference that you can make out in sound between wired and wireless speaker systems being that in the case of expensive speaker systems their connector cables are made with copper and gold in them and have crisper quality of sound, but this is hardly noticeable by the average person. Several manufacturers have started producing such speaker systems, easier to be installed, can be afforded by the average consumer, and still maintaining a high level of quality. There’s little doubt that in quality, wireless speakers are equal to, the wired ones as technology keeps advancing and the home theater industry shifts from wired speaker systems to totally wireless systems. It’s surely something that is going be seen in the not distant future.

Why Soundproofing Matters

Why Soundproofing Matters


There is an extensive variety of diverse ways that can be utilized when you are soundproofing a room. Also there are some different methods that you can utilize to ensure that this job is finished the way you want it to be.


When considering the room’s walls where you are functioning, you can utilize soundproof wall insulation. Even though most kinds of insulation will supply you with minimum few barriers against noise, insulation products are there that are particularly made for doing this also. This kind of product functions best for latest homes because it can effortlessly be fitted when the home is being built.


Suppose you are soundproofing a room in a present house, you may not want to become liable for the expense of having to purchase special insulation. Rather, you may explore other, less labor intensive and costly options. These comprise of buying blinds or drapes for no matter which of the windows that are situated on that specific wall. Because windows such as these will be a main conductor for any kind of activity that is happening outside of them, you would like to locate the thickest drapes still fulfilling your necessities for that room’s lighting. For extra protection from noise, also you can utilize both drapes and blinds in the windows.


A way that several people utilize when they are soundproofing a room is building one more wall on a present wall that is near to the street or a different house. While this practice is usually utilized by those who practice in their houses and play in bands, you can also utilize this method if you are troubled by too much external noise from the street or your neighbors.


By utilizing the thickest drywall you can locate, you would like to make certain that you also utilize soundproof wall insulation. A combination of this will possibly make your room incredibly soundproof. Also you will have the ability to hold your practice of band devoid of the fear of causing disturbance to your neighbors. Also you can be certain that neither the street activity nor your neighbors will be troublesome to you again.


Suppose tools are accessible to you, these modifications can be made by yourself. If time does not permit or suppose you are not experienced in this area, you can employ a contractor for doing this work for you rather. Suppose you have a budget, you can save additional money by performing the work yourself.


Suppose you want to soundproof a room in your house you can contact Moov Group who has experts in the field.

Soundproofing Your Home

Soundproofing Your Home


Soundproofing is insulation from noise and can be attained in one among two ways: lessening the noise and taking it in. While the first is an instance of bringing in distance between the listener and the noise, the second is about converting the sound wave and restraining with materials for damping that take in sound. These materials vary in nature – choose each depending on the kind of soundproofing job available. Below is a breakdown of many methods of soundproofing having gained recognition over the years.


1) Damping materials – As stated above, damping materials take in sound waves and restrict the production of hearable noise. The idea is ensuring the sound wave hits the materials for damping before it falls on the eardrums of the listeners. Some common materials for damping are itemized below.


  1. a) Lead is an efficient but expensive material which transforms waves of sound into heat over distance and time.


  1. b) Neoprene is a synthetic rubber also utilized as a damping material. Though, neoprene is not incredibly effective in taking in sounds of low frequency and can be burdensome to apply.


  1. c) Also foam is utilized for sound dampening, even though it does not completely take in the sound, since its porous nature yet allows waves of sound to travel, just not as effortlessly as possible for them in open air.


  1. d) Thermal insulators are a great choice in damping since they provide sound lessening and thermal control, giving you complete control over temperature and noise pollution.


  1. e) Polystyrene foam is an excellent choice when the issue is moisture. It helps treated structures to resist moisture while also functioning to absorb sound.


2) Cancellation Devices – Rather then using material to take in sound waves, cancellation devices like noise-cancelling headphones function by giving out sound that is contrary to the unwanted one. The contrary sound cancels the existing sound and produces a new sound hardly hearable to humans. Also cancellation devices function well to fight sounds of low frequency that could be hard to take in with damping materials. Similarly, cancellation devices let for granular control above hearable frequencies.


3) Room Within a Room (RWAR) – A room within a room is a well-liked technique of home soundproofing. The notion is preventing noise from leaving a specific area, instead of blocking the noise from entering a particular area. This is attained by constructing a room inside a room utilizing soundproof materials which cancels the necessity to treat the existing structure and makes it simpler for creating a soundproof space from the beginning.


4) Barriers – Sound barriers are usually used as to lessen pollution by noise in areas that surround freeways, highways, and remaining sources of usual noise. Barriers, though, are not utilized in businesses and homes since the ceilings, walls, doors, windows, and floors of these structures conduct sound, and should be treated separately to take in sound instead.


The main thing when soundproofing is considering the kind of job prior to choosing materials and a method. Options may differ whether soundproofing walls and floors or doors and windows, hence research before choosing a method and seek advice from a knowledgeable salesperson when purchasing materials.

Sound Insulation Testing

Sound Insulation Testing


The objective of sound testing is making sure your setup has adequate level of airborne and impact sound insulation depending on the regulations of building in your area. You could have to fulfill the requirements so as to ensure that your building is completely compliant. Let us know more about it.


What is tested?


How many walls and floors that you are going to test depend on the quality and type of the building besides the method of construction. In fact, the number of tests varies depending on the amount of buildings and also the quality of the buildings.


Is your building ready?


Prior to hiring a service for sound testing, it is suggested that you ensure that your building is prepared for the performance test. That is to say, the windows and doors must be fitted and closed. The systems for ventilation must also be correctly installed. Besides this, the sockets, light switches, and skirting boards must also be ready.


Cost of sound testing


Majority of providers offer helpful services for the amount paid. You could want to search for a service provider who gives significance to their customers. The “site fee” comprises of the equipment, reporting, and engineer’s fees. Generally, every test is charged individually so as to reduce your expenses. Additionally, for mass testing, you can obtain special discounts. Hence, the cost will differ based on the number of rooms that you would like to get tested.


Failed tests


If a test is unsuccessful, the company could offer a design or re-test service without charge. It is vital to remember that the engineer could let you know suppose the test is going to be unsuccessful. Actually, seldom the tests fail. Qualified acoustic consultants assess the buildings and offer advice on economical solution hence you can attain the highest standard. Keep in mind: corrective works could cost you plenty of money. Hence, you could want to get the work completed thoroughly in first attempt.


Airborne testing


The objective of an airborne test is measuring the resistance experienced by the sound when passing via a wall or floor. In fact, it utilizes an omni loudspeaker which is placed on one side of the floor or wall. This system generates pink noise.


Impact Testing


This is one more general kind of sound testing. In the impact testing, a tapping machine that appears like a football is used for doing the tests. This machine is placed in the rooms at the top and measuring of the noise is done. Subsequently the level measured is corrected on the basis of the time of reverberation of the background noise and also the time. This gives a precise outcome of the impact sound insulation.

Hence, if you have been seeking a way for getting your building tested for levels of noise, it is suggested that you hire a good company’s services. This way you can be certain that your construction has the correct level of noise.

Listening Room Acoustics: 7 Common Myths

Listening Room Acoustics: 7 Common Myths


You have invested a lot of money in a great hi-fidelity system; however something still does not sound correct to you. Unluckily, even the most costly system by itself will not automatically generate great sound. That is where room acoustics enter. Usually room acoustics is a misinterpreted field – and one where easily you can be deceived into spending cash on solutions that don’t fulfill what they assure.


Here is a look at seven usual myths of room acoustics.


1: Just Add Curtains And Carpets For Great Sound.


Curtains and carpets do not translate to a total acoustic solution. They only deal with the frequencies that are high – and they just cannot provide the defined performance of acoustic panels that are lab-tested. Worse, neither deals with the vital problems of boomy bass and speaker boundary interference.


2: Soundproofing Implies Good Acoustics.


Soundproofing and acoustic treatment are not the same. Soundproofing just stops sound from coming in or exiting a space – it does not deal with the inner sound reflections of the space. In reality, the bass problems will be more serious if you soundproof more, since low frequencies are confined inside.


3: That Boomy Bass Can Be “Tweaked”.


The wavelength of frequencies of bass implies that “tweaks” cannot solve the irregular bass decay time in a room. As an alternative, tweaks generally alter the balance of frequencies from mid to high corresponding to the bass. This causes you to ascertain less bass boom – however the problem is yet there.


4: Treatment Of Room Makes It Lifeless And Dead.


Professional design of acoustics makes living spaces. Its unrestrained abuse of thin acoustic material – such as egg crate foam – excessively absorbs high frequencies and dampens the sound in a room. Smart solutions aspire for flat diffusion/absorption throughout the audible spectrum.


5: Treatment Of Room Is Ugly.


These days acoustic panels seamlessly blend with your inner design and include beauty to your space. The trick is integrating room treatment while designing and building your listening room, rather than adding it later.


6: Room Treatment Is Costly.


You will find an array of prices for choices in room acoustics. A skilled consultant can assist you be a knowledgeable shopper and produce an affordable room in which you can actually enjoy the equipment for media you have already bought.


7: Answers Can Be Found On The Internet.


Each space is exclusive, and the internet cannot address the complications of your individual acoustic challenges. A skilled consultant with actual practice can save you money and time, mainly when introduced into the project early.

Improving Fellowship Hall Acoustics

Improving Fellowship Hall Acoustics


Similar to other kinds of areas for social gathering, fellowship halls face the frequent issue of reverberations of sound that interferes with the quality of acoustics inside the room. When a group communicates in a fellowship hall, specifically one that contains many hard, reflective surfaces, the combined voices produce reverberations that influence the performance of acoustics all through the area. While these reverberations get in the way of speech clarity, people obviously talk more loudly, creating an unending audibility issue that can add to an overall unlikable atmosphere. Absorbing these surplus reverberations to remove background noise and better speech clarity is the objective of several fellowship hall projects for acoustical improvement.


Implementing a treatment for acoustics aimed at regulating noise levels and making the quality of acoustics better inside a fellowship hall involves first knowing the behavior of sound being targeted. Suppose you stand alone in the fellowship hall and shout your name, a part of the sound energy produced by your voice will go through the ceiling and wall surfaces, while the remaining sound will rebound from the ceiling, walls, and remaining surfaces again into the room. When the time between the conclusion of your scream and the sound introduced again into the room is less than 0.1 second, is known as the reverberation time (whereas a time lapse of above 0.1 second is an echo). Reverberations happen so fast that they are considered as one extended sound.


The problem of reverberation of sound in a fellowship hall can be effortlessly alleviated through implementing a balanced blend of treatments intended to take in sound reflections. Several types of products for sound absorption are available in the market. This includes panels that are fixed to or hang from the ceiling, absorptive partitions that divide big areas into smaller ones and wall coverings and panels. In a fellowship hall after the proper treatments are ready, they will serve to take in reflections and cut down reverberation times, removing surplus noise in background. With the intervention made by surplus reverberations under control, usual conversation levels will come back and attendees will not have to any longer compete with surplus noise to be audible.


The solution to regulating reverberations and providing clarity of speech in a fellowship hall is applying adequate treatments without becoming over-enthusiastic. While it is needed to make certain that treatments are abundant to regulate reverberations on the basis of the room size and other factors that contribute, excessive treating of the room would not provide any additional benefits and become liable to needless cost. A qualified soundproofing consultant can make suggestions based on the individual features of the fellowship hall.

How to Find a Soundproof Home

How to Find a Soundproof Home


If you have had sound problems in the earlier period and are seeking a latest home you know very well the significance of locating a home that by now had some properties of soundproofing built in. It is usually very hard to measure the levels of sound in a home through the first walk through and all of us know that nobody wants to shift into a boisterous environment.


Most of the people, as per scientific research, in fact ignore noise. As per reports, a very less percentage of population becomes aggravated at extended sessions with high levels of sound. Scientists are not certain of the reason for the very low percentage however what they are aware is that an individual who has not had tolerance to noise in the past is not unexpectedly going to find it endurable. They are actually more irritated than anybody at hearing new sounds.


It is important to ensure that you locate a house that is as soundproof as feasible. For doing so, you will require doing a small amount of investigative work.


The foremost thing you will want doing is looking at the house very closely. Ensure you observe the windows to find out how thick the glass is and to make sure that the condition of the window is good. It is vital to ensure the proper opening, closing and sealing of the windows, both around the edges and on their close. Windows are an enormous origin of noise, also in walls that are finished with soundproofing materials. For soundproofing, double hung windows are the foremost while awning windows and casement windows are second and third respectively.


Also you will want to have an inspector or contractor observe the manner the systems of utility in the house were built. If the house is older the heating, plumbing, electrical or air systems could be old and, therefore, considerably noisy. Your best stake is having every system switched on while you are at home in order that you can listen to them for yourself.


Few other things are there that you can question yourself regarding the houses you are considering also. These include:


  • Where the rooms that are intended to be quiet are located. Are the bedrooms at the rear of the home or on the street?
  • Is there a squeaking sound in the floors? Are they hardwood or covered in rug?
  • Is there proper insulation in the home?
  • Is the home in a silent community or on a boisterous street?
  • Are you close to any main transportation lines?


The more you are aware about a home before the more you will know about the extent of soundproofing work that requires to be done. Ensure you set a boundary for yourself in order that you know accurately how eager you are for getting that work done suppose you purchase the house. If the sound level in the house doesn’t make you happy you must simply move on. The appropriate home will come along in time.
