Air Pollution and Climate Change
A known and often used method of insulation is represented by soundproof sponge, having the role of sound absorption and improvement of acoustics. The insulating sponge is used in recording studios, Radio TV studios, music rehearsal rooms, for upholstering acoustic enclosures having the role of acoustic correction.
The aim of the study is to improve acoustic characteristics of a room that was originally used as an office and is now used as a music rehearsal room and recording studio, making determinations of noise level during the acoustic set-up of the room. Soundabsorbing materials were used to improve acoustic characteristics of the room, to reduce echo and reverberations and sound-insulating materials to reduce noise penetrating from inside to outside of the room. Determinations performed compare the “efficiency” of traditional materials (polystyrene, mineral wool, etc.) and dedicated materials (soundproofing panels, sound-absorbing sponge, formwork sponge, etc.) used for improving acoustic characteristics of a room. In this sense, sound insulation measures had to be corroborated with the fact that in the vicinity of the music rehearsal room there are offices where the activity is predominantly administrative (IT offices, accounting offices, customer service offices etc.), situation in which the maximum limit allowed by national legislation is 60 dB (GD 493/2006, annex 1).
