Acoustics

Testing, Calibration and Consultancy

Automotive

We have unique specialist expertise in structure-borne sound including sound source characterisation – the in situ blocked force method and in situ transfer path analysis (TPA) method were both devised in our labs. We have a broad range of expertise in automotive acoustics, vibration and materials research including both experimental methods and modelling. We also offer a broad range of services to the automotive industry 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.

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

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

  • Structure borne noise and Vibration prediction
  • Noise source tracking/localisation
  • Sound and vibration source characterisation
  • Transfer path analysis / source path contribution analysis
  • Noise source rank ordering and treatment
  • Product noise modelling and auralisation
  • Shock tube testing
  • Vibration testing e.g. with Polytec laser interferometer or Guralp force-feedback accelerometers
  • Vibration isolator characterisation (dynamic stiffness measurements)
