Current strategies for dealing with loop gain are effective at eliminating whistling, but they inevitably result in a compromise on sound quality and/or the level of amplification you need to hear speech optimally. When this loop gain increases (for example, when you bring your hand up to your ear, or if your hearing aids are set very loud) feedback or whistling can occur. Loop gain is what happens when sound leaving the hearing aid re-enters through the microphone. Their existing reactive strategy is complimented by a more proactive system. To accomplish this, they combined two strategies. Their goal was to move from an attitude of feedback management to feedback prevention. This means that you, as the user, will be happier with the outcome of your hearing aid fitting. This means that we can potentially achieve optimal gain on an open fitting more often. With their new Velox platform Oticon Opn S has promised an additional 6dB of gain using an open fitting. As audiologists, we are always battling against comfort to achieve audibility and so Oticon offer us a solution for this. However, when we create a better seal people often feel blocked off from the world and it isn’t as comfortable. To overcome this we need to create a better seal between the hearing aid and the ear. It is ok for a hearing aid to do this when it is outside of the ear but as soon as it is in position you should no longer hear feedback.įeedback usually occurs when too much amplified sound is being put in to the ear and it leaks back out. What is feedback cancellation?įeedback is when a hearing aid whistles or squeals.
It samples the amplified sound 56000 times per second and is the most effective feedback cancellation system they have ever developed. This is an ultra-fast proactive technology. They have introduced a new Open sound optimiser. What makes the Oticon Opn S range different? They have since improved on their original portfolio by introducing the S range. To try and overcome this the original Opn was introduced to try and keep the users environment as ‘open’ as possible. This means the hearing aid might amplify the conversation to your left instead of the person you are trying to engage with on your right. Hearing aids in their present format don’t know what we are listening to. The main limitation they highlighted was closing down life. Leading up to the product itself we were asked a question, ‘What are the limitations of directionality?’. For the record, it doesn’t but what they have done is work towards reducing feedback on their hearing aids with their new processor. Oticon Opn S hearing aidĪlison Stone, audiology training manager, introduced the Oticon Opn S, which apparently breaks a law of physics. However, they also had some key updates to their portfolio which is what I’ll be focussing on today. The majority of the DRIVE targeted independent businesses to help us to deliver better care to you, our readers and clients.
Alistair Tait, managing director, kicked off the day with a warm welcome followed up by Mark Collins, national sales manager, who outlined the schedule and the goal of the DRIVE. Hosted inside the historic Twickenham stadium the day kicked off with some testimonial videos of individuals that have seen significant benefit from original Oticon Opn hearing aids. In March we attended the 2019 Oticon DRIVE where Oticon officially launched the Oticon Opn S hearing aid. Oticon Opn S launched at Oticon DRIVE 2019
