9.“They squeal in your ear.”
Feedback, as the whistling sound made by some
hearing instruments is known, is much less common
than it used to be. Digital technology, open-fitting
designs and careful fitting can cancel feedback,
minimizing it or eliminating it completely. It’s the same
with occlusion, a booming echo of your own voice
caused by hearing instrument designs that completely
seal the ear canal. These designs are used rarely today,
replaced by digital technology and open designs that
minimize or eliminate occlusion. Bottom line, today’s
hearing instruments are precise, clean-sounding and
more comfortable to wear than ever.
