Electroacoustics. Audiometric equipment - Instruments for the measurement of aural acoustic impedance/admittance Ingestion-build-93833 With the help of BSWhat is BS EN 60645 5 Audiometric equipment for the measurement of aural acoustic impedance about? BS EN 60645 is a European standard on electroacoustic that discusses the audiometric equipment for the measurement of aural acoustic impedance admittance to improve the acoustical performance of audiometric equipment. BS EN 60645 5 is the fifth part in the BS EN 60645 series that applies to instruments designed primarily for the measurement of acoustic
