Organization: ITU-T
Publication Date: 1 January 2012
Status: inactive
Page Count: 72
scope:

This Recommendation describes test signals which are applicable for several purposes in telephonometry. A wide variety of test signals is given, starting with low complexity test signals up to test signals with a high degree of complexity incorporating a lot of typical parameters of speech. Besides technical signals such as sine waves or noise, more speech-like signals are described.

The overview about the typical applications of the test signals described is a guideline giving general application rules. The detailed description of the application however should be found in individual Recommendations describing the measurement procedures for certain applications.

In order to avoid problems in creating the test signals described, all these signals are freely available for download from the ITU-T test signals database: http://www.itu.int/net/itu-t/sigdb/genaudio/Pseries.htm#P.501.
