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 our closed
ComfortTIP .

• Wax or debris can cause whistling.
Clean tubing/tip and ear canal,
and replace tubing/tip if they
appear worn.
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.
