Michael & Associates, Inc.

We can generate up to about 120 dBA continuous in the booth for tests requiring high SPL. We have an impulse noise facility that is about 20 x 60 feet of test space with minimal reflections. For the impulse tests, we use a shock tube built by Mark Cauble of BC Precision Tool in Cincinnati, and we use the GRAS 45CB test fixture that meets ANSI S12.42-2010. We're using Viacoustics Trident software with the Viacoustics Impulse Peak Insertion Loss Analysis (IPILA) package.  Our products include FitCheck Solo, FitCheck for Muff type HPDS, Muff-type HPD Force Measurement System, and STS Sub Terra Systems Water Leak Detector
