Aerospace

Acoustics is an important consideration in the aerospace industry both internally and externally to the aircraft and Salford University have worked on many research and consultancy projects in both areas.  For example, in collaboration with aerospace partners, the University has been developing  new  test procedures for the characterisation of structure borne noise sources and vibration isolators with a view to producing industry standard test procedures.  We also offer many standard tests, a short list of which is provided below.

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 Power to BS EN ISO 3744:2010 / BS EN 60704-2-1:2015
• UKAS Accredited Calibration Services

Other traceable standard test services we offer include:

• 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
• Silencer testing to 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 & 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
• Vibration testing e.g. with Polytec laser interferometer or Guralp force-feedback accelerometers
• Vibration isolator characterisation (dynamic stiffness measurements)
