1 Coupling of an insert earphone to the occluded-ear
simulator
2 Coupling of a behind-the-ear type of hearing aid to
the occluded-ear simulator
3 Coupling for in-the-ear type of hearing aid (modular
type) to the occluded-ear simulator
4 Coupling arrangement for an in-the-ear type of
hearing aid (custom-made) to the occluded-ear
simulator
5 Coupling arrangement for an insert earphone with an
earmould to the occluded-ear simulator
6 Coupling arrangement for a real-ear insert to the
occluded-ear simulator
A1 Example of one specific design of occluded-ear
simulator
Specifies a simulator for the calibration of insert earphones in the frequency range 100 Hz to 10 000 Hz in terms of the sound pressure at the eardrum. Defines terms used, and gives performance specification and tests, coupling arrangements, calibration details and a specific example for the design of such a device.
