How to Create Great Auditorium Acoustics With Quality Acoustical Products

Doing an acoustic treatment to an auditorium is not an easy task to do. The halls are so large and open that often they are highly reverberate and therefore in most situations carrying out acoustical treatment of an auditorium design becomes a very necessary thing to do.

The problem of realizing the best auditorium acoustics is tough because it calls for a satisfactory medium between live sound and dead sound.

When live shows (bands, plays, orchestras, speeches etc.) are being presented, there must be clear ring of words and notes all over the auditorium space.  This ring enhances the quality of sound and the entire audience is able to hear much better than before.

But there is a problem. It is that there exists a fine limit between a pleasing ring and an echoic confusion.  If the sound ring is too much it will quite dramatically and quickly reduce the quality of sound and the ability of the audience to hear with clarity.

If that is the situation, then what could be the solution? How is it possible for one to discover the happy spot between alive and dead, absent and disruptive, pleasant and painful ?

The solution lies in using a mixture of diffusion and absorption.

Diffusion disrupts and scatters the sound waves. The absorption lessens the quantity of noise present in the room so that there are fewer reverberations. This minimizes the slap-back echo (reverberation amidst two walls that are parallel) and lets the remaining sound to continue reverberating without causing disruption.

It is reported that similar treatments were carried out on some locations.

The rear wall of the auditorium is covered with absorptive panels. The sound after passing through the audience is absorbed by the panels reducing the quantity of secondary waves, that is, the waves that get bounced off an object, like the audience) and the audience is able to hear clearly.

In the above case by applying diffusion to the flanking walls the slap-back echo amidst the two side walls is removed.  But no noise is absorbed by them and hence the sound stays inside the rings and room.

So now it is clear that while in certain occasions creating an extraordinary auditorium acoustics may seem complicated, it isn’t impossible. One important thing to be kept in mind is that absorption must be kept to reasonable limits because too much of absorption will eradicate the ring which is essential in auditoriums where performances are held.  After that, whatever sound remains inside the hall may be controlled using suitable diffusers and your auditorium will turn into a great sounding performance arena in hardly any time at all.

A Sound Education Acoustic Problems and Schools Solution With Acoustical Products

A Sound Education Acoustic Problems and Schools

Below-par acoustics can result in setbacks in learning, particularly in the case of a child with hearing deficiencies or learning debilities. A school has several needs. They vary according to the design of its classrooms – the intelligibility of speech with least reverberation is most important in a typical classroom, but in a media center or library the same intelligibility of speech could disturb students from studying or reading. Take into account three important acoustical concerns when you renovate or design each space:

Background noise: Keep this as minimum as possible in a normal classroom so that the lecturer does not have to speak louder than the noise to be heard. Also, if background noise is too loud it can cause strain to the vocal chords of the teacher, and students may not hear properly.

Reverberation time: The ideal range is from 0.5 to 0.8 seconds, and it should be possible to readopt the room to reduce the time if a child with impaired hearing joins. You should avoid several reflections interfering with speech clarity.

Sound isolation: Often sounds leak into the classroom from adjoining spaces and cause distraction. School doors are generally lighter unlike acoustical doors which are heavier and block sound.

Identifying the Noise Problem

If staff members or students complain about noise, you must attend to the acoustical problem. Engaging an expert consultant is the simplest and most effective approach to find the real cause.

In schools, some of the common sources causing acoustical disturbance are people in hallways and adjoining rooms and noise created by computers, copiers, and other equipment, outdoor noises, HVAC sounds, and also excessive echoing as per a study conducted.

Professional organizations in the acoustical industry, have recommended databases for finding consulting firms. Some of these are certified by competent authorities which rates the acoustical consultants according to their expertise. Your consultants will check the reverberation time of your space, background noise level, sound isolation, and seal penetrations and any other paths that can allow sound transmission between classrooms.

Often schools have noisy gyms, cafeterias or classrooms. Usually such problems originate from poor acoustics or reverberation. There are many hard surfaces in few of these spaces, and much of the noise bounces around from children, which distorts speech.

Finding Acoustic Solutions

Address acoustics is easiest during construction, but in case of present buildings, this option I not valid. Some effective solutions are upgrading the door gaskets or just replacing the doors themselves and this will stop noise from leaking to adjoining rooms.

Noisy equipment can also cause extra background noise. A brand-new chiller or air handling unit or an old equipment that has not been serviced or cleaned regularly can also make extra noise.

A ventilator, and a HVAC unit for every room, and a duct work that is not insulated can cause distracting noise for students and teachers alike, particularly students sitting close to the ventilators.

 

Achieving Effective Acoustics in Hospitals – Block Noise and Cover Noise WITH Acoustical products and materials

Achieving Effective Acoustics in Hospitals – Block Noise and Cover Noise

Block Noise

Traditionally walls are used for blocking noise. While completely they will not prevent transfer of noise from a side to another, walls will lessen its volume when it passes through. The Sound Transmission Class (STC) rating of the wall denotes how well it lessens airborne noise. The rating of this must be “real-world” instead of lab-tested. The interior windows and doors STC rating must at least comply with the wall standard.

But, blocking includes more than walls since not only does noise travel via air; also it can pass via, over, around, and under obstructions, and through ways of penetrations. Structural elements, like ventilation ducts, should be properly located and treated for preventing cross-talk from one room to another. To the doors addition of sweeps or gasket material can be done based on the speech privacy level required while they are closed.

Also blocking of noise transmission can be done via a layout well-planned. Make sure machines (e.g. ice dispensers or medication) and areas of high-activity are alienated from areas needing quiet, like patient rooms.

Cover Noise

Majority of people know at least few factors of these initial two strategies and suppose they will attain the preferred levels of noise control and speech privacy if they just build “adequate” walls or provide “sufficient” absorption. This viewpoint is typically connected with the opinion that efficient acoustics can only be attained when in the space the general volume is low to the maximum extent possible.

But, similar to other ergonomic factors like temperature and lighting, actually there is a zone of comfort for the sound volume. This zone of comfort can be attained by regulating the noise floor. This is the level of constant background sound characterizing the space. If this floor is low it is easier to hear noises and conversations, also those that are comparatively less in volume or emerge at a significant distance from the hearer.

Providing a more consistent and higher baseline level of volume can effortlessly be attained by installing a system of sound-masking in the space. This is the least understood or known method of noise control, though extensively it has been used for decades, mainly in commercial offices.

A system of sound-masking comprises of loudspeakers in series, installed in a pattern like a grid over the ceiling, and a process of controlling their output and zoning. The sound distributed by the loudspeakers is unobtrusive and continuous, preserving the noise floor at a proper volume. When correctly implemented, it is very effective at concealing speech. Any noises lower than the masking sound level is also covered up. Besides, it lessens the impact of boisterous noises by decreasing the extent of change of volumes from baseline to peak.
