Abstract
An ear simulator has an inlet port (62), for receiving sounds from a speaker (18) of a communications device such a mobile phone handset (12), and has an outlet port (38) in an opposite surface. The ear simulator has at least one additional aperture (60) in the same surface as the inlet port (62), representing acoustic leakage around a mobile phone held against a user's ear. This allows the ear simulator to provide measurement results that more accurately represent the frequency dependent phase response of the transfer function from the handset loudspeaker driver to the ear of a user of the handset.
