What is the law of physics?
According to the laws of physics, a microphone too close to a speaker, creates feedback.
As a hearing care professional you want to give optimal gain to every client. While providing each person with the comfort of an open dome.
But this is often not possible due to the risk of feedback*. Until now, this law has restricted hearing care professionals in their fitting and trapped them in a world of compromise. A compromise on sound clarity and audibility due to reduced gain and a compromise on comfort due to closed fittings. Oticon Opn S changes all this.
