Abstract
Ubiquitous availability of media content through portable devices like media players and smartphones has resulted
in an immensely increased popularity of headphones in recent years. However, while conventional stereo recordings
usually create a good sense of space when listened to through loudspeakers, the sounds tend to be perceived inside
the head (internalized) when headphones are used for listening. A more natural perception in headphone listening
with sounds being perceived outside the head (externalized) can be achieved when recordings are made with dummy
head microphones or with microphones placed inside the ear canals of a person. In this study, binaural room impulse
responses (BRIRs) were measured with several commercially available binaural microphones, both placed inside the
listeners’ ears (individual BRIR) and on a head and torso simulator (generic BRIR). The degree of externalization
of speech and noise stimuli was tested in a listening experiment with a multi-stimulus test. No influence was found
for the stimulus signal, but the externalization scores were found to be lower for 0◦
incidence. With all microphones,
relatively high externalization scores were achieved, and for all but one microphone, individual BRIRs resulted in
slightly better externalization than generic ones.
