Private residence

Our rule of thumb for private homes
In our experience, most people who live in homes built and furnished according to current trends need to have a good deal of absorbing area installed.
After a large number of measurements and calculations, we have found that most private homes need a coverage rate of around 65%.

For example, if the room is 100 m2 and the coverage rate is 65%, 65 m2 of absorbent area is required.

The formula is as follows
m2 of the room / 100 x 65 = 65 m2.

This is, of course, a rough and experience-based approach. To be more precise, you need to carry out acoustic measurements in the home and base exact calculations on that.

Choice of sound class for the areas

There are no legal requirements for reverberation time in private homes yet. However, based on our experience, we recommend a reverberation time of 0.32 T/sec in a private home. This is somewhat higher than, for example, sound class B in the living room of a kindergarten, where the requirement is 0.30 T/sec. Experience suggests that reverberation in a home should not be more than in a kindergarten or classroom.

We refer to the Norwegian standard for sound in buildings, NS 8175:2019 Sound in buildings. The standard contains four sound classes: (A, B, C and D), the class is chosen based on the area's purpose of use.
