Optimising room acoustics

The quality of the acoustic foam is largely responsible for its absorption behaviour. In the meantime, there are many “acoustic specialists” on the Internet who too often sell customers unsuitable materials at cheap prices - at the same time, many dealers who offer this do not even know the difference between insulation and attenuation, that is, many are unfamiliar with this area and simply tell or promise that which the customer would like to hear. Does that help him?

The optimisation of room acoustics involves attenuation (less about outward insulation). An acoustic optimisation is very simple in principle: Ideally, choose high-quality acoustic convoluted, pyramid foams or acoustic foam planes for this purpose! Then select the thickness of the foam depending on the sound source: If this radiates in the medium or high frequency range, a foam with a thickness of 3 cm is sufficient to attenuate the resonance well. The lower the frequencies, the thicker the foam should be so that even low frequencies can be attenuated optimally. Thus if the sound source is very  “boomy”, select foam sheets with a thickness of 7 or 10 cm. Furthermore, you should also use thicker foams if the room is particularly high because the resonance is particularly noticeable here.

We recommend that our customers do not cover the entire room immediately. It is often sufficient to achieve a good result if you cover approximately 60% of the ceiling surface. Thus the surround sound remains “lively” due to residual sound reflections on the walls. If you line 100% of the surfaces, the room is anechoic - it reflects hardly anything!
