Previous hearing aids required the ear canal to be mostly plugged up; otherwise amplified sound would leak out from the ear and into the microphone again in an endless loop. This so-called 'acoustic feedback' has, until now, resulted in a very unpleasant and loud whistling.

Oticon has now found a solution that facilitates a more 'open-ear' fitting without the risk of feedback - a solution called OpenEar Acoustics™.

When you use Adapto your own voice sounds more natural. It also makes other sounds appear much clearer, without the risk of whistling or other annoying side effects.

How is this possible?
Years of research into digital sound processing, acoustic feedback, and audiology have led to the development of Adapto's groundbreaking Dynamic Feedback Cancellation approach. The system constantly monitors the instrument and cancels out any whistling even before it's heard - without compromising on speech understanding or sound quality.

The Dynamic Feedback Cancellation is so effective and reliable that it's possible to make large ventilation openings in the hearing aid. As the ear is not as plugged up, sound is allowed to escape from the ear canal without any whistling or other side effects.

Be confident with Adapto
Whether it's your earmould or hearing aid slightly moving in your ear when you smile or chew, or placing the phones by your ear - feedback is eliminated.

The operation of the Dynamic Feedback Cancellation is inaudible, so you still get optimal audibility and understanding in all kinds of situations.
