The Acoustic Research Laboratory is a part of ETS-Lindgren, which is located in Cedar Park, Texas, a community adjoining Austin, Texas. ETS-Lindgren is a subsidiary of ESCO Technologies, Inc. (NYSE: ESE), located in St. Louis, Missouri. The test lab is independently accredited by third-party accrediting bodies including the National Voluntary Laboratory Accreditation Program (NVLAP), and is also a part of an ISO 9001 and 1705 Management Program.

The lab uses a reverberant chamber for measuring sound transmission loss, and a hemianechoic chamber for sound power measurements. Our chambers are acoustically isolated on floating concrete floors and structurally isolated from the parent building. Each chamber also has its own acoustically isolated control room equipped with professional grade instrumentation and measurement equipment. The instrumentation is regularly calibrated by an independent, accredited third party. The chambers are designed for fast specimen throughput, and can easily accommodate multiple test specimens of various sizes.
