We offer a broad range of services that are suited to the rating or diagnostic testing and acoustic design of machines including standard test procedures and bespoke research.  For example, standard tests might include the measurement of sound absorption using the impedance tube or the measurement  of sound insulation in the transmission suite.  We have a broad range of expertise in machinery acoustics, vibration and materials research including both experimental methods and modelling.  

The following tests are quality assured to ISO/IEC 17025:

Sound Insulation testing to BS EN ISO 10140-2 / BS EN ISO 140-3 / BS EN ISO 717-1

Sound Absorption to BS EN ISO 354

Sound Attenuation of Hearing Protectors to BS EN ISO 24869-1

Sound Power to BS EN ISO 3744:2010 / BS EN 60704-2-1:2015

UKAS Accredited Calibration Services
