Designed for use in automotive NVH, cabin noise, vibro-acoustic testing, appliance noise evaluation, wind tunnel testing, and other critical sound and noise measurement applications, the company’s latest line of acoustic sensors and instrumentation includes prepolarized condenser microphones. These are available in 1/8”, 1/4”, and 1/2” diameters, as well as free-field, pressure, low-cost array, and random incidence types. Array microphones can be used as drop-in replacements within existing accelerometer test system set-ups for as-needed noise measurements. Models are available as stand-alone units or in a microphone and low-noise preamplifier combination with iTEDS on-board memory storage capabilities. All microphones are constructed with a stainless steel protective grid case and housing as well as a special stainless steel alloy diaphragm. Also available are a full range of preamplifiers, handheld calibrators, and accessories. ENDEVCO, San Juan Capistrano, CA. (888) 363-3826.
