Many measurements in audio applications have to be monitored for compliance with specified limit values. Therefore, sometimes a whole series of measurements have to be compared with a fixed limit value, in other case it might be necessary to define different tolerances for example for different frequency ranges. Both can be done using Audio Analyzer UPD or UPL. This application note covers the different possibilities of limit checking, it demonstrates how to edit limit files and presents a program to easily generate files for checking the limits of frequency response measurements. Furthermore the display modes for different kinds of references are explained.
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.
Present-day sound studios are hardly conceivable without A/D converters. A/D converters are essential components when music is recorded and they directly influence the recording quality. The current Application Note describes a test program permitting automatic measurements of all parameters of sound studio equipment with the aid of Audio Analyzers UPD or UPL. Measuring converter chips with mostly serial interfaces that are not to standard are not the subject of this Application Note.
Being faced with a wide variety of standards and manufacturer’s specifications, test engineers may often find it difficult to keep track of necessary audio measurements. This is aggravated by the fact that modern audio analyzers offer a multitude of settings. This application note serves as an aid offering a collection of typical setups that make it possible to get started with measurements immediately. In addition, information is given on associated standards, on the adaptation of the setups to specific measurement tasks as well as on the evaluation of results.
