SAVE

Whisperwool absorbs the frequencies in the main speech range without overdamping (300 to 3500 hertz). Whisperwool acoustic panels are highly sound-absorbent above a frequency of 100 hertz (lower values have not been recorded). Whisperwool has a very good "early decay time" (EDT Early Decay Time), a benchmark from acoustics that evaluates the perceived reverberation time (reverberation).

​

The distance to the wall increases the absorption in the low frequencies, and with additional back insulation the absorption effect can be increased. As a result, it usually only takes half the area compared to other systems to achieve pleasant rooms.

 

Even a small amount of Whisperwool sound absorbers leads to a high acoustic efficiency. In this way, costs can be saved.
