Acoustics tests are carried out in a chamber specially equipped according to requirements of standard UNE-EN ISO 140-1. The soundproof room of the STRUGAL Technological Center laboratory permits to carry out tests to sample up to 10m2.
Acoustic insulation to sound is measured in the laboratory.
The quality of acoustic insulation to noise is calculated taking in account both the sound pressures level between the issuing chamber and the receiving one and the sample surface, the volume in the receiving chamber and its absortion area.
