Noise Measurements and Acoustical Testing

MULLINS ACOUSTICS owns a variety of sound level meters, calibrators, tape recorders, noise dosimeters and other instrumentation to measure sound and vibration.  Capabilities include:

• environmental noise monitoring, from a few hours to several weeks,
  including statistical levels (Lmax, Lmin, Leq, L10, L90, Ldn, SEL)

• 1/3 and 1/1 octave sound level measurements

• narrow band frequency analysis  (FFT)

• vibration measurements  (accelerometer and calibrator)

• industrial noise dosimeters (OSHA)

Instrumentation is tested periodically and has current laboratory certifications, traceable to NIST standards.  Portable calibrators are used routinely in the field during measurements to verify ongoing accuracy.

In addition to the instruments we own, we can rent specialized test equipment for projects.

Some of the measurements and tests that we routinely perform include:

· STC and NIC tests  (walls and ceilings)

· IIC tests  (floor-ceiling impact rating)

· NC measurements  (background sound level indoors)

· RT (Reverberation Time) measurements

· machinery noise & vibration

· environmental noise measurements (short and long term)

· product noise testing

· audio system set-up and commissioning

· workplace noise levels  (short term measurements and personal dosimetry)

· specification compliance testing

· noise ordinance compliance measurements

· audio demonstrations of accurate sound levels
