Underwater acoustics

World-leading underwater acoustic expertise and facilities

NPL’s underwater acoustics metrology work underpins the protection and sustainable exploitation of our oceans, providing traceable calibrations required by regulation to make absolute measurements of sound in the ocean. Acoustics is the preferred modality for imaging, positioning and navigation in the offshore energy industry and marine technology.

We offer a wide range of services including calibration of hydrophones, free-field acoustic testing and characterisation of sonars, testing of transducers using simulated ocean conditions, calibrating digital marine autonomous recorders and a wide range of acoustic nearfield methods for characterisation of large aperture sonars.

In addition, we can develop new standard procedures to meet evolving industry needs, for example for the in-situ measurement and assessment of underwater radiated noise from offshore activities, such as marine construction and shipping. We also provide consultancy to developers and users of underwater acoustic equipment.
