标准简介：This part of IEC 60318 describes an acoustic coupler for loading an earphone or hearing aid
with a specified acoustic impedance when determining its physical performance characteristics,
in the frequency range 125 Hz to 8 kHz. It is suitable for air conduction hearing aids
and earphones, coupled to the ear by means of ear inserts e.g. ear moulds or similar devices.
The sound pressure developed by an earphone is not, in general, the same in the coupler as
in a person’s ear. However, it can be used as a simple and ready means for the exchange of
specifications and of physical data on hearing aids and for the calibration of specified insert
earphones used in audiometry.
