Zusammenfassung:In order to ensure normal ambient conditions, people should be provided with a comfortable environment in residential and non-residential facilities: lighting, temperature, humidity, noise level, etc. The current issue in residential soundproofing is high noise transmission between flats located on the same floor. As a rule, this issue is addressed by increasing the thickness of soundproofing material at the expense of living space. Highly porous lightweight materials are used: cork, polyethylene foam, polyurethane foam, TermoZvukoIzol. The practical application of these materials revealed an insignificant acoustic effect as they are used to insulate impact noise. With the state-of-art vibroacoustic equipment and approved methods, the multimethod research was performed to study foam rubber as a material that increases acoustic comfort. It was found that acoustic comfort could be achieved by using the Russian vibration/sound absorbing polymer composite materials without sacrificing significant space.
