Artificial Ears Types 4152 and 4153
have been designed for measure-
ments in the audiometric and related
fields. They enable electroacoustical
measurements on either insert ear-
phones or headphones to be carried
out under well defined acoustical con-
ditions, which are of great importance
for the comparability of different de-
signs and the reproducibility of meas-
urements.
Artificial Ears Types 4152 and
4153 consist of an acoustic coupler, a
main housing containing the sockets
for the connection of a Brüel & Kjær
condenser microphone and a base
plate with a mechanism for clamping
the object being tested.
The clamping mechanism is spring
loaded and provides a force which can
be adjusted from 2 N (approx. 0.2 kg)
to 10 N (approx. 1 kg) as recommend-
ed by the relevant ANSI Standards,
the actual force value being set on a
scale engraved on the clamp holder.
To minimise the effect of vibration
during the measurements, each Arti-
ficial Ear is isolated from shock and
vibration by means of three soft rub-
ber feet.
Artificial Ear Type 4152
In Artificial Ear Type 4152 the socket
for mounting the measuring micro-
phone permits use of a Brüel & Kjær 1″
