Demands for improved sound insulation in homes have increased significantly, particularly due to the development of teleworking. ChovA, a company specializing in waterproofing and thermal and acoustic insulation, has recently created a new range of systems to reinforce the levels of sound insulation between partitions.
In order to verify that a soundproofing device meets the requirements of a renovation project, it is necessary to comply with essential conditions: easy, reliable and adapted measurements and data analysis. To improve its testing capabilities in this area, ChovA turned to Hottinger Brüel & Kjær (HBK) for the provision of solutions that comply with the latest regulations.
After consultation, HBK offered ChovA a complete kit including a class 1 sound level meter, Type 2270, for carrying out measurements in accordance with current standards. A Type 4231 acoustic calibrator to check the calibration of the Type 2270 before each test, as well as a Type 4296 sound source and a Type 2716 power amplifier. A 1/3 octave graphic equalizer ensured that the pink noise emission from the OmniPower source had the flattest possible response across all free-field frequency bands.
