Do you live with several people in your home? Then it is important that everyone can do their thing without being a burden to each other. Good acoustics are of great importance here.
At a school you have the situation that many children or students are in a relatively small space. So make sure that the acoustics in the classroom or canteen are in order.
In call centers it is clear that the acoustics must be in order. Both for your employees on the telephone and for the conversation partners on the other side of the line.
