Abstract

NPL, in association with other national metrology institutes, including DPLA Denmark, PTB Germany, and OFMET Switzerland undertook a calibration intercomparison, the purpose of which was to ensure the harmonisation of measurement standards for boneconduction audiometry within Europe. The project was split into two parts; Part A - a round robin investigation to measure the mechanical impedance and force sensitivity of a selected mechanical coupler and; Part B - a radial investigation to measure the output of a bone vibrator driven by a defined voltage with NPL acting as the central coordinator. The report concentrates on Part A and provides background discussion on the formulation of the project, describes the measurements made by all participating laboratories, collates and compares the measurement results, and offers discussion and conclusion on the findings. Documentation of Part B is limited to a presentation of the data submitted by the participants.
