The effect of the revolutionary OpenSound Optimizer™

OpenSound Optimizer analyses amplified sound at an astonishing 56,000 times/sec so it can detect and prevent audible feedback proactively, even before it occurs. This enables you to fit users with up to 6 dB more gain, in an open fitting – without the risk of feedback.*

• Oticon Opn S offers optimal gain and sound quality throughout the day
• Oticon Opn S eliminates audible feedback in static and dynamic environments

From feedback management to feedback prevention

The new ultra-fast detectors and breaker signal in OpenSound Optimizer prevents feedback from occurring.*

1. Hearing aid without feedback management
No anti-feedback system, no detectors: Audible and uncomfortable feedback rises and persists, dramatically reducing speech understanding.

2. Traditional anti-feedback with slow detectors
With this reactive technology, feedback rises and becomes audible. Utilizing gain reduction and other measures, the hearing aid slowly returns to stability. Audibility, sound quality and speech understanding are compromised.

3. Hearing aid with OpenSound Optimizer
With ultra-fast detectors feedback risk is identified and breaker signal is instantly engaged in risk areas – before sound quality is affected – preserving audibility and speech. As the feedback risk decreases, breaker signal is seamlessly deactivated, with preserved audibility and speech.
