About CCi Acoustical Testing

Noise Measurement and Compliance Validation

Site Acoustics dB(A) noise map of a data center site over satellite imagery, with sound-level contours and labeled receiver levels

We use Site Acoustics Scout to measure noise on site and compare it with the levels Model predicted, across the facility and at nearby receptors. That confirms compliance and shows where mitigation will help most.

We currently offer the following:

Standard Acoustic Testing

  • measuring high-frequency damping
  • reverberant acoustic chamber testing
  • wind tunnel testing
  • free-field acoustic testing
  • reverberation time / absorption testing
  • general damping measurements
  • impedance measurements
  • testing of dominant airborne and structureborne noise sources
  • testing of dominant airborne and structureborne transmission mechanisms

Field Testing

Electric power generators and enclosures using the following standards:

  • SAE J1074 Engine Sound Level Standard
  • European Commission 2000/14/EC CE Directive
  • EN ISO 3744: Acoustics - Determination Of Sound Power Levels Of Noise Sources Using Sound Pressure : Engineering Method In An Essentially Free Field Over A Reflecting Plane
  • ISO 8528-10: Reciprocating internal combustion engine driven alternating current generating sets
  • Ground vehicles
  • Rail systems
  • Heavy machinery

Aerospace testing

  • Acoustic qualification and acceptance tests for spacecraft
  • Simulating acoustic loads to determine transfer functions and component response levels

Vehicle interior noise and transfer path correlation

  • anechoic or free-field simulated acoustic sources
  • reverberant field excitation of vehicle
  • structural excitations and resulting structureborne noise and vibration
  • extensive experience designing and overseeing wind tunnel validation testing for vehicle interior noise and transfer path correlation.

We would welcome the opportunity to discuss your noise and vibration project.
