Soundproof booth
SPECTRA
Modular concepts, the cabins with controlled environment of SPECTRA can be integrated in all the processes. They make it possible to obtain an ambient noise level, inside the cabin, sufficiently weak to measure acoustic pressures about 20dB (A). Absorbent the internal treatment of the walls adapted to each case makes it possible to obtain a cut-off frequency in the low frequencies.
The buildings of the anechoic chamber are carried out in walls with very strong insulation and are equipped with nanomaterials with very strong absorption (dihedrons "melamine PU foam").
SPECTRA conceives and establishes you:
- Anechoic chambers and semi-anechoic (also called soundproof room); allowing to find the conditions met in outside (free field)
- Testing grounds (driving or different); determination of characteristics other than acoustic,
strong capacity of insulation of the envelope of the bench
For each case, it is necessary to also take into account the constraints of insulation compared to outside, visibility, accessibility, ventilation or airconditioning, lighting, etc
