Abstract

The invention relates to an audiometer (100) and to a method of conducting audiometry. The audiometer (100) includes at least one circum-aural earphone (102) for positioning over an ear of a patient, the circum-aural earphone (102) including a microphone (202) directed outwardly for receiving external or ambient sound, and an acoustic speaker (238) directed inwardly. The audiometer (100) also includes at least one inner earphone (104) operatively arranged within the circum-aural earphone (102), the inner earphone (104) including an in ear piece (106) for positioning in the ear, a microphone (230) directed outwardly, and an acoustic speaker (220, 221 ) directed operatively inwardly. The audiometer (100) further includes a control module configured to perform a first phase of active noise reduction and a second phase of active noise reduction and to emit a hearing-test sound via the speaker (220, 221 ) of the inner earphone (104).
