We have a broad range of services available for the marine sector.  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. 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:

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

Reduction of Impact to BS EN ISO 10140-3 / BS EN ISO 140-8 / BS EN ISO 717-2

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
