2. Instrument makes a whistling sound.
• Whistling (feedback) occurs when
amplied sound returns to the
microphone and is re-amplied.
• Most hearing aids whistle when
not inserted properly. Try
reinserting the ComfortTIP
™
into ear canal so it ts better.
• Lower the volume.
• If whistling occurs when you
raise the volume, try using a
Closed ComfortTIP.
• If whistling occurs after trying
a Closed ComfortTIP, you might
require more gain (volume) and
should try the High Volume Kit
(see page 18).
• Clean any wax or debris from
Tubing/Tip and/or ear canal.
Whistling will disappear when
the condition is corrected.
Please note: When an object (hand, hood, person, chair, wall... etc.)
comes close to your ear while wearing hearing aids, you may experience
whistling. This is normal for all microphones when temporarily obstructed,
not just microphones in hearing aids.
