Acoustics

Testing, Calibration and Consultancy

Machinery

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:

Other traceable standard test services we offer include:

  • Sound Power Testing to BS EN ISO 3741 / BS EN ISO 3743 / BS EN ISO 3745 / BS EN ISO 3744:2010 / BS EN 60704-2-1:2015
  • Impedance tube testing for normal incidence sound absorption and transmission loss
  • Sound intensity methods to BS EN ISO 9614-1:2009 / BS EN ISO 9614-3:2009 / BS EN ISO 15186-3:2010
  • Ventilation duct silencer testing BS EN ISO 7235:2009 / BS EN ISO 11820:1997

We also offer a broad range of non-standard measurements, diagnostic testing and R&D services including:

  • Structure borne noise and Vibration prediction
