Ipsilateral and Contralateral Earphone: is
integrated in the probe system.
Probe frequency transmitter and receiver and
pressure transducer is integrated in the probe
system.
Generally the instrument is made and
calibrated to be within and better than the
tolerances required in the specified standards:
