Based on my research, the easy answer is no. Open cell spray foam performs better than closed cell, but neither is effective at blocking sound transfer. The qualities that make it an excellent thermal barrier also create disruptive resonance and its adhesion couples the wall elements together increasing noise transfer.
Is spray foam good for sound deadening?
Spray foam insulation for sound deadening can be used for the ceiling if you have an attic above. Spray foam and injection foam both completely fill the cavity where they are installed. This makes it a great insulation material when it comes to reducing, not eliminating, noise in your home.
Does foam insulation work for soundproofing?
Spray foam insulation is not a good choice for noise reduction, as open and closed-cell spray foam is more suitable for thermal insulation, not sound insulation. This is because they are not good at blocking sound waves, but are good thermal insulators as they reduce air infiltration.
How good is soundproof foam?
Acoustic or Sound Absorbing Foam Acoustic foam works fairly well at sound absorption and can be used to acoustically treat a room to improve the quality of sound. It is widely used for treating recording studios and theaters.
