Measurements on Hearing Aids with the Audio Analyzers UPL and UPD

There are proposals for broadband measurements on hearing aids, for example the proposed standard ANSI S3.42. Such measurements are intended to simulate more accurately the behaviour of hearing aids under normal hearing conditions also in the presence of ambient noise. Audio Analyzer UPD fitted with High-Speed Option UPD-B3 makes it possible already now to generate the proposed test signal and to perform all the related measurements including coherence and transfer functions. These measurements may become more and more important in the future but have scarcely been performed up to now as they require highly complex test equipment. Audio Analyzer UPD enables the user to measure to tomorrow’s standards even today.
