Abstract

This report describes the work undertaken within the project AIR/2013/A3 'Provision of traceable standards for medical ultrasound' supported under the National Measurement System 2013-2016 Programme for Acoustics and Ionising Radiation Metrology. Two 1 mm active element membrane hydrophones have been calibrated using NPL's primary standard laser interferometer for the BIPM/CIPM key comparison CCAUV.U-K4 'hydrophone free-field open-circuit sensitivity in the megahertz frequency range', piloted by NPL. The hydrophones were calibrated once at the beginning and again at the end of the key comparison.
