Our engineers, all of them members of the Institute of Acoustics, are fully qualified to carry out a range of tests including sound insulation tests, environmental noise surveys and mechanical services compliance testing to name a few. At our in-house research and development facility we constantly strive to improve the quality and performance of our products, in particular the ongoing refinement of our attenuator range. We do this in our fully compliant ISO 7235 installation, where we can test insertion loss, flow noise and pressure loss of attenuators.
