Acoustic comfort
A good acoustic environment is absolutely essential to maintaining a high level satisfaction and moral health among residents.
The main elements that impact indoor noise involve indoor noise source and outdoor noise. For the indoor environment noise, electronic instruments (such as radios and televisions) are the main noise sources, and outdoor noise source involves traffic, industry and life noise. However, in big cities, the impact of outdoor noise on indoor comfort is a primary sector, so the indoor acoustic environment and comfort are also chiefly decided by outdoor noise. A good acoustic environment keeps noise at levels that do not interfere with activities within programmed space.
Acoustics and productivity
Studies show that a worker’s productivity increases with an improved acoustic environment that allows ease of communication, limited intrusive noise (and resultant distraction), and protection from ear damage where appropriate
Noise should be dampened to such an extent that it no longer interferes with the activity you were set out to do. Just 30 dB(A) is disturbing to sleep. Noise with sound levels of 35 dB(A) or more interferes with the intelligibility of speech in smaller rooms.

Acoustic insulation
Most of our lives are spend indoors. It is thus crucial that the buildings we live and work in are made in a way that reduces noise inside a room, between rooms and prevents noise from the outside penetrating into the building.
To achieve the desired sound quality, sound insulation and absorption have to be carefully designed to achieve the desired acoustics environment.
Roxul stone wool, by its basic engineering is the perfect material for the purpose of achieving a desire acoustics performance. Roxul stone wool consists of fibroporous basalt stone with air-filled interconnected spaces. Because of this structure the stone wool has obtained excellent acoustic properties, as they significantly diminish occurrences of vertical sound waves on wall surfaces. The result of this is improved room sound insulation and material sound absorption with a reduced reverberation time, thus lowering the sound level in adjacent rooms.
