Annotation
This part of IEC 60318 specifies an acoustic coupler for the measurement of supra-aural audiometric earphones in the frequency range from 125 Hz to 8 000 Hz. The sound pressure developed by an earphone is not, in general, the same in the coupler as in a person's ear. However, the acoustic coupler can be used as an objective and reproducible means of measuring the output of supra-aural earphones. It can be used for specifying reference equivalent threshold sound pressure levels (RETSPL) for the calibration of audiometers.

Электроакустика - Средства моделирования человеческой головы и уха - Часть 3: Акустический адаптер для калибровки выше слуховых наушников используется в аудиометрии
Эта часть IEC 60318 указывает акустический адаптер для измерения выше слуховых аудиометрических наушников в частотном диапазоне от 125 Гц до 8 000 Гц. Звуковое давление, разработанное наушником, не является, в целом, тем же в разветвителе как в ухе лица. Однако акустический адаптер может использоваться в качестве объективного и восстанавливаемого средства измерения вывода выше слуховых наушников. Это может использоваться для указания пороговых уровней звукового давления стандартного эквивалента (RETSPL) для калибровки аудиометров.
