MOUTH SIMULATOR
Mouth Simulator are high-performance artificial mouths conforming to ITU-T Rec. P.51 and delivers highly accurate and repeatable electroacoustic measurements.
MOUTH SIMULATOR are designed to test telephone transmitters, smart speakers, and other microphones where a sound field similar to the human voice field is required.
The
Mouth
Simulator
also
provides
a
reference
source
for
near
field
testing
of
handsets
and
microphone
based
devices,
in
smart
devices.
The

closely
replicate

generated
by
the
human
mouth,
as
specified
in
IEEE
269
and
