Method and apparatus for testing earphone apparatus

Apparatus for testing earphone apparatus (10) during manufacture includes a head simulator (30) including an ear simulator (40) defining a passageway (42) leading to an external opening (44), a and an eardrum microphone (46) mounted in the passageway (42) of the ear simulator (40). The apparatus (10) includes one or more of: an ear plate (50) for simulating an outer ear, the ear plate (50) forming part of the ear simulator (40) and defining a substantially planar earphone engagement surface (52) substantially encircling the external opening (44); a mounting guide system for assisting correct placement of earphone apparatus on the head simulator (30) relative to the ear simulator (40); and a test module (100) for performing rapid automated testing of earphone apparatus mounted on the head simulator (30).
