What is flexible polyurethane?
Flexible polyurethane foam (FPF) is a polymer produced from the reaction of polyols and isocyanates, a chemical process pioneered in 1937. FPF is characterized by a cellular structure that allows for some degree of compression and resilience that provides a cushioning effect.
Is polyurethane foam good for soundproofing?
Polyurethane is quite effective at attenuating high frequency sound waves, but it does not provide low frequency isolation unless sufficient thickness is used. The porous nature of polyurethane greatly reduces acoustic reflection, but this low density also allows for the transmission of sound energy.
Is polyethylene foam good for soundproofing?
Polyethylene Foam Roll's best application as a soundproofing material is as a sound barrier in or on walls, ceilings, or floors. It is most effective when used as a component of a multi-layered construction scheme.

Is polystyrene good for acoustic treatment?
Expanded polystyrene is quite good at not transmitting sound, but that's because it reflects a lot back. So quite good for soundproofing and thermal insulation (if enclosed in suitable fire-resistant material), but not good for acoustic treatment in a studio.
Does thick foam absorb sound?
Foam does not Block Sound Transmission Even covering the wall 100% with 2” thick foam is not going to, to the extent of the person's expectations, stop that sound from traveling right through the wall. Acoustical foam is porous and does not block sound simply because it is porous which allows sound to pass through.
How thick should acoustic foam be?
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.
Does the shape of acoustic foam matter?
For instance, an L shaped space will need different acoustic foam considerations than a room in a square shape since room shape plays a role in the way sound frequencies travel. In fact, for most locations, the best solution is to combine the different types of acoustic foam to get the best results.
Will any foam work for soundproofing?
The short answer is No. Unfortunately egg box type foam does not stop sound transferring through your wall from your neighbour or from leaving your room. All it will do is absorb some of the sound within your room and stop it echoing and amplifying.
