This International Standard specifies a means of describing the physical characteristics of audiometric test and reference signals of short duration and methods for their measurement. The standard also specifies a psychoacoustic method for determining the level of the test signal in terms of hearing level. Requirements for the information to be given in an instruction manual are also included. This standard does not describe the method of use for test signals of short duration or specify the waveforms to be used in clinical practice.
The object of this standard is to ensure that audiometric stimuli of short duration are specified and measured in the same way and that calibrations are carried out using defined methods.
