Hearing instrument testing, also known as test box measurements or HIT box measurements, are measurements that assess whether a hearing instrument’s performance meets manufacturer specifications with…
Test procedure Launch the Equinox Suite from Noah, OtoAccess®, or standalone. Click on the AUD tab on the upper right-hand side of the screen. Ensure that your audiometry has been performed ahead of…
Description: We have found that by detaching the capacitors across the isolation bridge the eclipse becomes less sensitive to noise intruded on the mains ground wire. Furthermore the signal to noise…

In cases where you detect a symmetrical hearing loss, traditional audiometry without masking is usually sufficient. However, be aware that in cases of asymmetrical hearing loss, one cannot be certain…

This quick guide outlines the procedure for creating a pass/refer DPOAE test protocol. Parameters and settings should be based on an appropriate pass/refer criterion. Open the Titan Suite software an…

No, the Eclipse does not have a notch (i.e. band-stop) filter. A challenge of these tools is that the line noise is only selectively eliminated with very steep slopes (sharp cut-offs) on either side…
