Primary measurement standards for sound in air:

• NPL provides primary measurement standards appropriate for the wide range of acoustical measurements in air. These standards support sound pressure measurements for manufacturing and product QA, health, safety and hearing conservation, environment noise measurement and monitoring, and many other applications.
• Dissemination of the measurement standards is undertaken to a degree through NPL's own calibration service. However the support provided to UKAS laboratories by this project is also vital for their effective operation, enabling traceability to be spread far more widely than NPL could manage alone.
• The facilities require continual incremental development to keep pace with (or even drive) the understanding of the physics underlying the calibration process and embodied in specification standards. From time to time the facilities also need significant re-development to keep pace with changes in IT and to replace instrumentation before it becomes obsolete.
