OAE Probe Specifications:
Probe:
Application:
DPOAE measurements
Dimensions:
(W x D x H) 12 x 26 x 11 mm (exc. Eclipse)
Weight:
3 g (exc. Cable, exc. Eclipse)

Note ! The OAE probe is dedicated to one Eclipse only! Calibration is stored on the Eclipse. Replacing
the OAE transducer will require new calibration of the transducer connected to the Eclipse.
DPOAE Calibration:
Probe stimuli L1 and L2 are calibrated individually in SPL values using the IEC 711 ear simulator coupler
made in accordance to IEC 60318-4.
The DPOAE module uses an improved method of stimuli level control, which more accurately delivers the
specified intensity in the full range of ear canals, from infants to adults. The applicability of the IEC 60645-
6 standard is currently limited to adult ears. Therefore, in order to better serve a market with a product
that provides more accurate stimulus levels to a wide range of ear canal volumes (specifically infants), we
have elected to utilize a more comprehensive calibration procedure for DPOAEs that is outside the scope
of IEC 60645-6 for some protocols.
This improved method of stimulus control is enabled when the “Use Microphone compensation” checkbox
is checked. To use the IEC60645-6 calibration method, uncheck the “Use Microphone compensation” in
the Advanced tab of the protocol setup.
