IEC 60645-1:2001 PDF

Scope: This part of IEC 60645 specifies general requirements for audiometers and particular requirements for pure-tone audiometers designed for use in determining hearing threshold levels, in comparison with standard reference threshold levels by means of psychoacoustic test methods. The object of this International Standard is to ensure: a) that tests of hearing, particularly threshold, in the frequency range 125 Hz to 8000 Hz on a given human ear performed with different audiometers which comply with this International Standard using methods described in ISO 8253-1 and ISO 6189 shall give substantially the same results; b) that the results obtained represent a valid comparison between the hearing of the ear tested and the reference threshold of hearing; c) that audiometers are classified according to the range of test signals they generate, according to the mode of operation or according to the complexity of the range of auditory functions they test.
