What Do Acoustic Diffusers Do?

Acoustic diffusers are a necessary addition to auditoriums, cafeteria, music rooms and presentation areas. As the name implies, they scatter the reflected sound into many different directions. The effect is high-quality sound within any room.

High-quality sound is especially important in music schools and music studios. If your room is suffering from high levels of background noise and high reverberation time, it will definitely benefit from sound diffusers.

There are actually many different types of diffusers. There are those that are specifically made walls and there are those that are specifically made ceilings with acoustic tiles. In terms of shape, they could either be in pyramid or barrel form with a square base. They can come in a variety of different finishes.

A company that specializes in sound diffusers won’t have a cookie-cutter solution across all spaces. Instead, it would identify what is causing the acoustic problem and make a custom solution for it.

For example, one company that worked on the Pennsylvania Academy of Music identified high ceiling, drywall ceilings and walls, and hardwood floors as the main cause of the school’s sound problem.

The company solved the problem by installing a fabric-covered wall system that reduced reverberation time by fifty-five percent and sound diffusers that produced high-quality sound.

In order to reduce the reverberation time, 432 square feet of 85 wall panels were installed six feet from the ceiling on the front walls cut the reverberation time. Also, 36 sound diffusers were installed on the lateral and rear walls to improve the sound quality for everyone in the room.

Those with a professional ear for music would know the difference that an acoustic diffuser makes.  Diffusers can scatter around ten times the sound as flat ceiling tiles.

Not all acoustic diffusers, however, would have the same sound absorption capabilities. Sound scattering capability is measured in terms of sound scattering coefficient. If an acoustic diffuser has a coefficient of 1.0, it means that it reflects 100% of sound, and scatters it in all direction. A coefficient of 0.0 means the sound is only reflected in one direction.

There are many companies out there that offer sound diffusers. If you don’t know where to find them, just search for “acoustic diffusion products” plus the name of your area on Google.

Don’t be content with hiring the first company you encounter online. Instead, be a smart client and ask for a quote from at least three companies.

As we said before, acoustic diffuser companies typically do not offer cookie-cutter solutions. That said, make sure to have a company representative visit the area where acoustic diffusers are to be installed before a price estimate is issued. Also, when it comes to the actual hiring, price shouldn’t be your only consideration. You should also consider the warranty and company’s previous work. That said, ask for a list of former clients.

The cost of installing custom sound diffuser solutions really depends on how many panels need to be used in order to decrease the sound reverberation time.
