Sports halls, swimming pools and fitness centers

In areas where there is activity and a desire for good attenuation and shielding of sound, it is important to have a lot of and correct sound attenuation, known in technical terms as sound absorption.

Most rooms tend to have hard, parallel walls and surfaces, which causes reverberation (echo). And in some cases, the sound "bounces" between the walls, known as "flutter echo".

Reverberation and flutter echoes are eliminated by installing absorbers at "speaking height" on the walls as well as in the ceiling. At the same time, acoustic partitions are well suited to creating "quiet zones" and attenuating directional sound, while providing visual screening. In open, large rooms, it is also effective to install absorbers that hang from the ceiling, such as rafts or baffles.

After carrying out a large number of measurements, calculations and installations, we have found that most living areas need a coverage rate of around 65% in relation to the floor area to be good and usable rooms for most purposes. If there is extra headroom, a higher degree of coverage is often required.

A combination of sound-absorbing ceilings, absorbers on the walls, carpets and special sound-absorbing furniture and pictures/decorations can be achieved "everywhere" and to such an extent that the conditions are very good for the users.

The formula is as follows
Room^m2 / 100 x experience-based coverage rate of 65% = X^m2

Example
The room is 75^m2 / 100 x 65% = approx. 48.75^{m2 of} absorbents are needed in the room.

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

If this simple procedure is not good enough for your needs, we offer exact measurements and calculations in accordance with current rules and regulations (NS8175, NS8178 and TEK 10/17.)

We help you from start to finish and deliver complete and effective solutions. From acoustic measurement, remote assessment, calculation of needs, solution and product proposals and installation. Read about the whole process here
