Acoustics in non-residential construction and infrastructure

What's the problem? Station Lelystad
In places such as under buildings, in tunnels, parking garages, station departure hall, apartment galleries and schoolyards, reverberation (echo) is created because hard and smooth surfaces (concrete and glass) of the building provide reflections. The noise problem that occurs here is the nuisance experienced by local residents. These problem areas require products that are suitable for outdoor applications and are resistant to moisture and weather influences.

What is the solution?
Reducing nuisance for the environment is most efficient by using as much Absorption material as possible. The sound pressure in these places is often such that at least 80% of a reflective surface (eg the ceiling in a parking garage) must be provided with an Absorbent material for a good result. Treating walls with, for example, a coarse stucco layer gives an improvement because sound is diffused (high-frequency sound is therefore scattered, direct reflection is greatly reduced.

The parking garage is a good example because the entire building consists of smooth concrete and there are several noise sources (vehicles in this case) in several places in the building. By providing the ceilings completely with, for example, Akotherm, the reverberation decreases to such an extent that there is no longer any nuisance within the parking garage and for the environment. The materials are mounted after the facilities such as ventilation, lighting and traffic signs have been installed. This application also applies to tunnels and departure halls.
