- Accurate and consistent measurements of airborne sound fulfil a wide range of regulatory, health, safety and commercial needs both within the UK and in support of international trade.
- NPL's ultrasonics expertise covers calibration, research, knowledge transfer, and products and services.
- Underwater acoustics is a key underpinning technology in offshore oil and gas activities, is increasingly used in oceanographic and environmental studies, and continues to play a crucial role in defence.
- Unique underwater acoustics measurement capability includes two open test tanks that provide a flexible approach to the most demanding testing requirements.
- Calibrations of the free-field sensitivity of miniature hydrophones of the type used to characterise medical ultrasonic fields.
- For customers who require their measurement grade microphones to be calibrated to the highest possible accuracy, the NPL Acoustics group offers calibration by the internationally agreed reciprocity method.
NPL provides world-class standards for measurement and calibration, and key expertise in measurement related research and development covering the fields of sound-in-air, ultrasonics and underwater acoustics.
We have purpose built facilities including reverberation and free-field rooms, environmental test facilities, open laboratory tanks and water sites for underwater measurement. Our leading measurement scientists additionally provide tailored training courses in various aspects of acoustics and are able to develop bespoke systems and products to solve industrial measurement problems.
The NPL Acoustics team supports hospitals and clinics, occupational and environmental health, and offshore marine activities.
