5.3 Tip selection and probe tting
Appropriate tip selection and good probe t are essential to ensure
successful recordings. A good probe t will help to block out external noise
and enhance the OAE signal. The Otoport is supplied with a full range of
tips to t all ear canal sizes. When selecting a tip, rst inspect the ear to be
tested to assess its size and to check that it is clear and free from debris. If
debris subsequently enters the probe sound tubes, do not attempt to clean
them; the coupler tubes should be changed. The correct size tip will look
slightly larger than the ear canal and should t snugly, forming a complete
seal with the ear canal wall.
5.3.1 Fitting for newborns
Gently lift the pinna upwards, away from the baby’s head, and then towards
the back of the head. This will open the ear canal.
Insert the probe at approximately 10 o’clock (for left ear) or 2 o’clock (for
right ear).
Turn the probe ear piece to 12 o’clock.
Hold the probe for several seconds. Then release the pinna and let go of
the probe.
