COMMON CAUSES OF ACOUSTIC FEEDBACK INCLUDE:
New hearing aids users often experience an effect known as acoustic
feedback, commonly referred to as "whistling." This occurs when
amplified sound leaks out of the ear canal and is picked up by the
hearing aids' microphone, creating a feedback loop. It is more likely to
occur at higher volume settings.
Excessive earwax buildup in the ear canal
Improper hearing aids fit or placement
Deterioration of hearing aids components over time
Incorrect ear tip size or style
Obstruction or compression of the hearing aids microphone
