Porous sound absorbing materials can efficiently absorb high-frequency noise with a wide sound absorption frequency band. ... Flexible PU foams have been extensively used for absorbing sound and reducing noise because of their good sound damping, viscoelasticity, and low den- sity [1].

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.
Does PU foam absorb sound?
PU is a significant sound absorbing material owing to its relatively low density and high porosity. It can be converted into ordinary soft foam, high elastic foam, or other porous materials as required in diverse applications.

Is polyurethane foam heat resistant?
Above all, it demonstrates good thermal parameters — it is resistant to a wide range of temperatures (from –200°C to +135°C). Average thermal conductivity coefficient of polyurethane foam is 0.026 W/m2, and the most favourable apparent density after the curing of rigid foam is usually 35 – 50 kg/m³.
