Acoustical Foam for Industrial Noise Reduction

Introduction

Acoustic Foam is a product which comes in many shapes to help reduce reverberation (echo) in various spaces such as recording studios, schools, manufacturing plants, gymnasiums, pools or any area where speech intelligibility is important. Foam comes in lots of shapes and sizes to meet just about any aesthetic need. It is very lightweight and can easily be glued or mechanically fastened to walls or ceilings. It can also be used inside of housings for noisy machinery or computer server rooms to reduce the noise trying to escape into nearby areas reducing the need for hearing protection or making an office environment more comfortable.

 

What is Acoustic Foam?

Acoustic Foam is made of a foamed ceramic called melamine. The Acoustic Foam starts life as a “bun” (similar to a loaf of bread) which has it’s crust cut away revealing a large clean block that is cut into all of the different forms it is finally sold as. This is a Class A fire rated material that has open cells that takes the energy out of reflected sound, reducing the time noise stays in the air. The shorter the time the clearer all the new sounds (human speech, music, etc..) become because they are not competing with all the other sounds in the air.

 

Why is Acoustic Foam Important?

Acoustic Foam is a very versatile material that is both a cost effective and attractive solution to echo problems. Studio Foam is important so a recording engineer can get a clean track that isn’t cluttered with room noise.  Acoustic foam panels placed on the walls and ceiling of a studio vocal booth make it so the recording is very clear and just the voice with no extra sounds. More and more these days we are having online video conferences both from the office and home office. I’m sure you’ve had a call where someone was very difficult to understand because their room has lots of echo. Sound foam can help tame the room sounds and make your meetings much more pleasant and effective.

You may work in an industrial or manufacturing plant where machinery is loud and can cause hearing damage. It can help reduce the sound pressure and how far the sound travels if the room is large. Soundproof foam (Alphasorb Composite Foam) is a combination of our Audioseal Sound Barrier and Alphasorb Flat Foam that combines the two products into a very effective sound blocking and absorbing material that can be used to line interiors of machinery housings and reduce noise the workers are subjected to. Getting noise levels down below OSHA standards can save a business significantly by not requiring hearing protection and annual hearing checks tests for their employees, quickly paying for the investment in savings.

Examples of Acoustic Foam

As mentioned above Acoustic Foam comes in a variety of finished forms and finishes:

Acoustic Foam Panels – for use on walls or applied to ceilings.

Acoustic Foam Baffles – for hanging from ceilings in a perpendicular orientation where all sides of the material are exposed to the sounds making them a very effective sound absorber.

Acoustic Foam Ceiling Tiles – to be used in drop ceiling grids

Acoustic Foam Bass Traps – for rooms that have issues with low frequency issues or standing waves.

Acoustic Foam Cloud Panels – for hanging parallel to the ground where all sides of the material are exposed to the sounds making them a very effective sound absorber.

 

Tips for Working with Acoustic Foam

  1. When applying to a surface using adhesive, make sure your surface is clean and dust free before applying. Only apply the adhesive just prior to placing to avoid the adhesive skinning over and not sticking properly.
  2. Use an electric turkey carving knife when cutting to get the cleanest edges – the 2 blades cut without pressing in and deforming the Acoustic foam so you don’t get the “jaggies”.
  3. Keep the scraps from your trimmings as they are the same material as a popular “magic” cleaning sponge.

 

Summary

Acoustical Foam is a very cost effective and versatile material that has many forms to help solve a wide variety of acoustical problems efficiently and attractively. Give me a call and let me help you develop a solution for your environment.
