100
he KU 100 dummy head is a binaural
stereo microphone. It resembles the human
head and has two microphone capsules built
into the ears. When listening through
high-quality headphones it gives the il-
lusion of being right at the scene of
the acoustic events.
When using the KU 100 dummy
head, the binaural stereo experi-
ence moves the listener into the
scene of the original perfor-
mance, in contrast to other
space-related recording tech-
niques, where the acoustic
event is moved to the listener.
The dummy head is also used in
many industrial applications as a
measuring device, for example in
acoustic research.
The KU 100 can be operated with
typical 48 V phantom powering, or
from an external power supply
unit, or from the built-in battery.
At the bottom of the unit is a
switch for the different power
supply modes, as well as connec-
tors for balanced and unbalanced
output signals.
Inside the head are additional switch-
es for 10 dB attenuation and the high-
pass filter.
The Idea
The KU 100 dummy head is a replica of
the human head with a microphone built into
each ear.
When the recorded audio sig-
nal is reproduced through
high-quality headphones the
listener perceives a sound im-
age almost identical to the one
he would have heard at the re-
cording location of the dummy
head (head-related stereopho-
ny).
When played back through
loudspeakers, the sound match-
es to a high degree that of con-
ventional stereo microphones,
placed in the same position.
However, a superior quality is added, that of a
distinct spatial depth perception.
