Facilities
Acoustic Analysis & Measurement
The facilities include a variety of equipment for acoustic signal measurement and analyses from leading manufacturers (Bruel & Kjaer, Larson-Davis, G.R.A.S., Quest, Fluke, Tektronix, B&K Instruments) including pressure and free-field microphones, calibrators, sound level meters, couplers, ear-simulators, KEMAR acoustic manikins, a Klangspektrum Klangfinder Twinface ear-simulator system, probe-microphone systems (2 Etymotic ER-7Cs and 2 Etymotic ER-10B+), and signal conditioners, and signal conditioners. For dynamic measurements, we use a custom Outline ET250 3D turntable that can rotate any of our acoustic manikins via precise computer control. The laboratory also has acoustic analysis software including EASERAâ„¢, Adobe Audition, B&K Pulseâ„¢, and custom MATLAB analysis software.
