Acoustical standards
Uncertainties
The uncertainties quoted in the descriptions below are expanded uncertainties representing a confidence level of approximately 95 percent.
Consultation services:
- pertaining to national and international acoustical standards, legislation and regulations;
- acoustical calibrations and measurements;
- noise and vibration problems including accelerometer calibration;
- acoustical measurement and calibration system design;
- precision mechanical, electrical, and electro-acoustical designs and system implementation; and
- ultrasound power measurements and calibrations, and transducer design.
Facilities
Specialized space available includes an anechoic chamber with a low frequency cut-off at about 80 Hz, a relatively large measurement space (15.2 m x 8.8 m x 6.7 m) for indoor semi-free-field measurements, and complementary acoustical instrumentation.
