Connecting the Test System
For performing audiometric calibration measurements,
connect the components as shown below.
The microphone is threaded into a connection inside the
artificial ear and the microphone preamplifier is inserted into
the opening on the side of the artificial ear base and threaded
into place. A microphone extension cable connects the
microphone preamplifier to the input of the System 824.
One of the audiometer earphones, connected to the
audiometer via a cable (not visible here), is placed on top of
the artificial ear and then the weight is placed on top to hold
it firmly in place.
