Directory of Accredited Laboratories
Acoustical Testing Services
Accreditation is available for selected test methods in the areas of sound absorption, impedance, attenuation, vibration, power levels, emitted sound and hearing protection, among others. This accreditation program is designed to satisfy the requirements of contractors, state and local governments, and federal agencies specifying accreditation for laboratories that perform testing for compliance to acoustical design specifications and performance testing of acoustical materials and noise protection devices.
The present test methods for which a laboratory may seek accreditation are listed in NIST Handbook 150-8. Other test methods may be added to the program upon request, if they are found to be appropriate by NVLAP
Listed below are all laboratories accredited within this program as of May 18, 2012. For additional information, contact NVLAP at (301) 975-4016.
