Which Acoustic Foam To Buy?

acoustic foam panels come in different thicknesses

You are designing your new studio and whether it is in your basement, your spare bedroom, your apartment or a commercial space you will inevitably need some sort of sound absorption material like acoustic foam, insulation or homemade acoustic panels. The type of material you require depends on what you are trying to accomplish with the sound absorbers and what frequencies you need to control.


If you are trying to reduce slight flutter echoes in your room then a few one inch thick acoustic panels might do the trick. On the other hand if you are building a vocal booth you may need almost full coverage of two inch thick acoustic panels.


Our acoustic panels come in four thicknesses and we also offer bass traps. Each thickness absorbs sound waves at different frequencies. Thinner acoustic foams will absorb the high and mid spectrum sound waves while thicker panels absorb high, mid and lower end sound waves.


1 inch thick acoustic foam will give you the most bang for your buck. 1 inch foam panels are thin compared to our other foams, but are still effective for reducing flutter echoes and controlling the mid and high frequency ranges. Use these panels when good sound control is desired but substantial absorption is not imperative.


2 inch thick acoustic foam offers more sound absorbing power overall, and will take care of the mid to high frequency ranges. The 2" thick profile is the most popular and a safe bet for anyone planning a DIY vocal booth, studio, home theater, rehearsal space, or a broadcasting area.


3 inch thick acoustic foam will help absorb high, mid, and low end frequencies. These versatile panels can be used in almost any room.


4 inch thick acoustic foam has the highest sound absorbing power, and will help eliminate lower frequency ranges to help tone down bass. Use these panels in rooms with low-end problems.


Bass traps are super thick foam pieces that go into the corner of your room and are the best for absorbing, you guessed it, BASS. If you have a subwoofer, bass amp or nice big monitors it is always good to have a few bass traps.
