Device makes a whistling sound.
• Whistling (feedback) occurs when
amplified sound returns to the
microphone and is re-amplified.
• Most hearing aids whistle when not
inserted properly. Try reinserting the
ComfortTIP
™
into your ear canal so it
fits better.
• Lower the volume.
• If whistling occurs when raising the
volume, you might need more gain
and should try the closed
ComfortTIP (see page 21).
• Wax or debris can cause whistling.
Clean tubing/tip and ear canal, and
replace tubing/tip if they appear
worn. You may also consider an ear
canal wax removal solution.
Please note: When an object (hand, hood, person, wall, etc.) comes close
to your ear while wearing hearing aids, you may experience whistling.
This is normal for all microphones, not just microphones in hearing aids.
