The acoustics of test rooms is related to noise transmission issues (outward if noisy equipment is inside the room, towards inside if acoustic metrology in the room imposes a particular level of background noise) and on the other hand with challenges in terms of anechoicity (if it comme to a test bench, the reflections of sound waves on the walls should be limited, if it is an anechoic chamber, the necessary must be done to restore inside almost perfect free field conditions as observed outdoors).

A diversified portfolio for testing rooms acoustics
ITS offers soundproofing products and equipment for testing rooms acoustics (anechoic chambers, wind tunnels, test benches) for new constructions projects or for retrofits.
Such means are an integral part of a program of technical measures to reduce sound transmissions, from the inside to the outside of a testing room (then, in general, to limit its impact in terms of noise), or from the outside to the inside of a test room (then, in general, to limit background noise), and to create specific sound propagation conditions, inside the test room, e.g. reproducing the acoustic free field, with or without reflecting ground, in a frequency band of interest, for which acoustic measurements are envisaged.
On-site measurements, design, construction (with or without installation) are part of the range of products and services marketed by ITS in terms of testing room acoustics.
