Recording studios, conference rooms, schools, cinemas and also personal toilets make use of acoustic diffusers to manipulate, lessen or amplify the sound. The feeling of being part of the action in a cinema hall, and being able to listen to the lecturer speak right in front of the lecture hall wouldn’t have been possible without acoustical materials.

When builders or architects want to make full use of the space they have, and not permitting the sounds to escape the enclosed area, they look for acoustical materials. The noise can be diffused, echoes can be emitted and sound vibrations can be dampened using an air compressor cover and different types of acoustical materials for various purposes. It is important to use these materials in cinemas and recording studios for the best sound quality. Use of acoustical materials can be categorized into three categories such as diffusers, sound absorption and sound proofing of sound waves.

Sound proofing

What sound proofing does is that it blocks the sound from a confined space from leaving the area and also permitting any external sounds from entering the area. ...
... These are generally used in recording studios and cinemas to improve the movie experience and get better quality recording by preventing any undesired sound being recorded. Sound proofing can be done on the floor, ceiling, doors and walls. With the confined area properly sound proofed from wall noise, the sound quality is improved. Moreover, for instance if your house is near a train station, you might want to consider sound proofing as it would keep the noise out from your house enabling you to sleep peacefully at night.

Sound absorption

Sound absorption is commonly used in recording studios as sound proofing doesn’t eradicate the fact that sound wave would reflect on it, causing echoes and inferior quality recordings. If sound proofing is used together with sound absorption, it would permit for the best quality recording. Sound absorption might not only be used in recording studios but also in restaurants. Some restaurant across the world would make use of it to lessen the noise of dishes cluttering and people walking to ensure a more peaceful environment for their customers to dine in. Absorber materials generally absorb sounds of more than 500 Hz. Rigid fiberglass is the most commonly used material to work as an absorber.

Diffusers

Diffusers are generally applied in confined areas that have flat walls and ceilings that are parallel to each other. With this structure type, the sound waves would just keep reflecting on the walls and ceilings causing a reverberation. One of the most inexpensive ways to create a diffuser that adhere to noise complaint Chicago is by using a few sheets of plywood and putting them at an angle along the ceiling and the wall. This would make the sound waves hit the plywood and get reflected in various directions and thereby diffusing the sound.
