Demand for improved acoustic insulation in the home has risen sharply, not least due to the growth in teleworking. ChovA, a company specializing in waterproofing, thermal insulation and soundproofing, has recently created a new range of systems to enhance soundproofing levels between partitions.
In order to verify that a soundproofing system meets the requirements of a renovation project, a number of essential conditions must be met: easy, reliable and appropriate measurement and data analysis. To enhance its testing capabilities in this area, ChovA turned to Hottinger Brüel & Kjær (HBK) to provide solutions that comply with the latest regulations.
After consultation, HBK offered ChovA a complete kit comprising a Class 1 sound level meter-analyzer, Type 2270, for measurements in compliance with current standards. A Type 4231 acoustic calibrator to check the calibration of 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 was used to ensure that the pink noise emission from the OmniPower source presented the flattest possible response over all free-field frequency bands.
