Abstract

NPL, along with partners from Denmark, France, Germany, Norway, Sweden and Switzerland undertook a calibration intercomparison for audiometric earphones, the purpose of which was to ensure the harmonisation of measurement standards for air-conduction audiometry within Europe. The project was organised radially, with NPL acting as the central co-ordinator and each of the participating laboratories using their own IEC 318 artificial ear systems. This report explains the background to the project, describes the measurements made by each of the partners and presents the results. Overall the results were encouraging, with differences generally no greater in magnitude than ± 0.5 dB between the partners, at the common audiometric frequencies.
