A remarkable acoustic optimized school project. Through professional consultation by Delhom acoustique the classrooms and corridors have large sound absorbing surfaces. Besides the ceiling, at least 1 wall was made with vitAcoustic wall absorbers.

Nicely integrated in the overall bamboo design by gmp · International GmbH (Architekten von Gerkan, Marg und Partner).

The target was, that the kids can calm down and concentrate better in a quite and sound optimized acoustic environment. Whoever will visit this school will hear the difference and will want to sit down for a while and relax.

This project has been a challenge for our teams, because of the very very short delivery time for 3 floors, 30x classrooms with corridor and classroom inbuilt furniture, receptions desks, library, kitchen furniture, water dispenser, acoustic flower pots in PAC and much more.

In order for a room acoustic measure to be calculated and assessed realistically, well-founded acoustic physical basic knowledge and practical experience is appropriate. In particular, the initial values of reality must be determined accordingly. For sensitive areas, the measurement should be carried out professionally by an acoustic expert. Alternatively, at least a provisional measurement should be performed with a phone app repeatedly. The provisional measurement serves only as a guideline for the selection of the room materials and their absorption coefficients in the acoustic calculator. Basically, any calculation without professional measurements of the initial situation is hypothetical!

Example:

Low frequencies are absorbed differently than high frequencies. Glass surfaces (Windows) or a normal office cabinet made of chipboard in different thicknesses, when you hit the resonance of the deep tones, can act for the low frequencies absorbing. However, a correct calculation is hardly possible due to the lack of measured data of the objects. On the basis of a measurement, special depth absorbers (vibrating resonators) need to be specifically set.

The calculations are based on measured data from objects and materials. Some of these are listed in the DIN 18041 exemplary. Others are taken from various sources for their correctness and conformity with the actual existing object or material there is no guarantee.

• Area is important-small elements, for example, are simply overlooked by lower frequencies due to the long wavelength. Even with a-class absorbers, an adequately large absorbing surface is required in relation to the size of the room. In communication rooms, absorbers on the ceiling are sparingly and consciously dealt with. Here is more of a reflection desired!
