Electroacoustics. Hearing aids - Methods of measurement of performance characteritics of hearing aids under simulated in situ working conditions Ingestion-build-264231What is BS EN 60118 8 Hearing aids testing about? BS EN 60118 8 is the eighth part of an international multi series standard that covers electroacoustics techniques for testing hearing aids. BS EN 60118 8 establishes certain guidelines for simulated in situ measurements of hearing aids. BS EN 60118 8 also describes a simplified method for simulated in situ measurements of hearing aids and a description for determination of the directivity index (DI)
