Anechoic Test Chamber

The WMU anechoic chamber provides the WMU Noise and Vibration Laboratory with the capability to:

   1. Measure and compare sound radiated from noise sources in any direction desired in an environment simulating the free-field conditions (i.e., free of echoes)

   2. Measure and compare total sound power of machinery according to standards commonly used in the industry
using an array of microphones surrounding the source.

This facility, which has been certified for testing in the frequency range of 125 Hz and above (internal dimensions of 6x6x6 feet), is located in room F-108 of the CEAS building. In order to prevent external sounds and vibrations from interfering with measurements conducted in this chamber, it is structurally isolated from the rest of the building via spring isolators.
