We are a full-service vibration and noise consultancy. Due to the demanding nature of most of our design work, we maintain world-class test and measurement capabilities. Therefore, not only do we design systems and structures, we test them and measure their performance, as well. We currently have the expertise and instrumentation to perform testing and measurements including:

• Multi-channel time history, narrowband FFT, and true fractional-octave signal analysis

  • full long-waveform "tape-recording" directly to disk
  • high-resolution narrowband FFT from DC to ultrasonic frequencies
  • true single and 1/3 octave band analyses; synthetic analyses at any bandwidth
  • post-hoc analysis under variable analytical conditions

• Sound intensity (PWL) and sound pressure (SPL) measurement and testing

  • PWL measurement for source specification or regulatory compliance
  • SPL measurement for indoor and outdoor ambient criterion or regulatory compliance
  • outdoor SPL measurement for noise ordinance (Title 24 / CNEL, Ldn, etc.) compliance

• Interior acoustical measurements

  • SPL testing of indoor noise levels in homes and industrial settings
  • Sound Transmission Class (STC and FSTC) testing
  • Impact Isolation Class (IIC and FIIC) testing
  • Reverberation time (RT-60) testing
  • Room absorption testing

• Forced excitation (hammer testing) of foundations, structures, and tool pedestals

  • foundation stiffness determination
  • transfer function testing between locations
  • structural accelerance / mobility / acceptance FRF testing

• Experimental modal analyses of tools and sensitive equipment

• Long and short term property line noise monitoring to determine compliance with ordinances

• Electromagnetic field (EMF / EMI) measurement and reporting

Each of these services may be conducted on a long-term or ongoing basis.
