Akustik - Simulatoren des menschlichen Kopfes und Ohres - Teil 4: Simulator für den abgeschlossenen Gehörgang zur Messung an mittels Ohreinsätzen an das Ohr angekoppelten Ohrhörern (IEC 60318-4:2010); Deutsche Fassung EN 60318-4:2010
Overview
This part of IEC 60318 describes an occluded-ear simulator intended for the calibration of insert earphones in the frequency range from 100 Hz to 10 000 Hz. It is suitable for air conduction hearing aids and earphones, coupled to the ear by means of ear inserts, for example, ear moulds or similar devices. The occluded-ear simulator is also suitable as the basis for an extension intended to simulate the complete ear canal and the outer ear (for instance, in head simulators). The responsible Committee is Joint Subcommittee GUK 821.6 "Hörgeräte und audiometrische Messtechnik" ("Hearing aids and audiometric measurements") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
