How to Choose an Office Sound Masking System Plenum system and Direct Field system

How to Choose an Office Sound Masking System – Part 2: Plenum system and Direct Field system

Plenum System

Initially, the sound masking systems were fitted on the grid over the suspended ceiling. Big loudspeakers were clamped to the concrete surface above, and suspended with a chain. The sound from the speaker would then be blasted upward towards the concrete surface which will rebound around the inner space between the ceiling tiles and the roof surface called the plenum. Therefore, these older type systems were named ‘plenum systems.’ It was intended that the sound would rebound around till the plenum is filled and then infiltrate into the office space below through the tiles. This kind of arrangement was a necessity 50 years back, considering the level of speaker technology which existed then and the existence of ceiling structures that were comparatively uniform and plenum spaces that were empty. This looks sensible: speakers of those days sounded loud with a very narrow angle of dispersion however, if you are able to rebound the sound around for quite some time this limitation can be overcome.

But, as plenum spaces started getting filled up with various fittings and ceiling assemblies turned more complex, the job of getting the plenum filled uniformly with sound became still more challenging, and sound could not pass down into the office rooms below with any kind of uniformity. Today, plenum spaces are fully occupied by ducts for air conditioning and heating, network and low-voltage cabling, and electrical conduits for lighting etc. Ceiling assemblies are turning out to be acoustical nightmares of a combination of absorbent and reflective materials, disturbing the spectrum as well as volume. To remedy this, several plenum systems devised more and more complex methods to improve their speakers (usually where there are 3-speakers). But – it was only just like a band-aid solution.

Direct Field system

Therefore acoustical engineers continued working, and developed the prototype that would eventually be called a ‘direct-field’ sound masking system. Recognizing the fact that the problem is too big to be overcome by continuing with the old methods of patchy solutions, they took out the speakers from the plenum and placed them outside. But just by using speakers made for bouncing the sound about inside the plenum the problem is not solved because they had a comparatively narrow angle of dispersion. Using the old-type speakers under the new configuration didn’t work either. There still existed the problem of ‘hot and cold’ points that were non-uniform.

At last engineers, taking the idea from the home theater business, developed a speaker with ultra-wide-angle dispersion, which could spread out the sound at an angle of 170-degree. This became the key solution to bring in the new level of sound masking in offices that was effective- and because the direct-field system that resulted is simpler, which removed the human errors in tuning the system and the intricate failure-prone technological systems, it had practically no failure.

The rubber that mounts for preventing vibration are made of assists stopping the vibrations from arriving at the metal or wood to stop that irritating noise from disturbing favorite show of everybody.

Majority of people do not comprehend this because they are making their personal cooling system for the first time. Ensuring that there exists sufficient room for air circulation in the cabinet will be helpful in reducing unnecessary noise.


More fans

Just install them, and subsequently turn every fan on low. It will be much quieter doing this than utilizing less fans and turning them on high.

Make Color Coordinated Seating Sections Using Auditorium Chairs

Make Color Coordinated Seating Sections Using Auditorium Chairs

Large spaces like theaters that are to be used for conducting shows or performances need to be divided into different sections that are going to cost differently to viewers. Naturally the tickets for seats closer to the stage will be priced proportionately higher than for those seats which are farther from it.

One of the problems faced by several commercial venues is that viewers who bought tickets for cheaper seats occupy the more expensive seats once the show begins. One easy method to prevent this from happening is to install colored chairs in the auditorium for each section. Then issue every viewer with a colored stamp to be affixed on their hands that matches the color of the section they are going to occupy.

Red chairs could be placed in the front rows. When the man who checks the tickets at the entrance sells seats for the red section he will stamp the ticket holder’s hand with a red mark. Then whenever the patrons leave their seats and return, the ushers will check the people and ensure that they are occupying the right seats.

You can purchase auditorium seats in many different colors so that you could divide the area into few sections according to the proximity of the chairs to the stage from visibility point of view. Then the tickets can be priced accordingly.

If the stamping of the hand of your customers is not preferred you could tie plastic wrist bands according to the color of the seats. The wrist bands are easily identifiable by the ushers when patrons move in and out of their seats.

The colored bands also avoid confusion. People will make sure that the chairs they are occupying are of the same color as their wrist bands. They can also easily come back to their seats using the color codes of the sections.

Many sporting stadia have replaced the bleachers with auditorium chairs. The color coding helps the fans find quickly where their seats are. In a large stadium when you want to find your seat in the concession stand you can get lost, but with the color wrist band you can easily find your seat.

The wrist bands and the color coded seats would be also helpful if a child is lost in a stadium or an auditorium. The announcer could help the parents to find the child. The ushers could also help by taking the child to the proper section in case the child is unable to tell them the location of their seats. The colored band would guide them to the location where the parents are seated. The child is re-united with the parents quickly.

Auditorium chairs are available in different colors to create different sections within an area.
