The Oticon Nera uses Feedback shield technology, the most advanced feedback protection system ever designed by Oticon. Feedback is that annoying whistling sound sometimes heard at public events. It is caused by sound from the speaker getting back into the microphone, the sound is then processed through the amplifier and the same path is taken by the sound again and again causing the whistling to occur. The same thing can happen with hearing aids particularly when high volume settings are required or when wax is present in the ear canal preventing the sound from being absorbed by the ear.
Feedback Shield uses three processes to control and limit feedback
The three processes work in harmony to suppress feedback and maintain optimal sound quality.
Oticon Nera hearing aids have a traditional binaural noise management system to identify noise as opposed to speech and reduce the volume to avoid the noise becoming uncomfortable. If speech is detected the level is automatically increased so that important sounds can be heard.
Most Oticon Nera styles are equipped with directional microphones that work automatically to focus when the user is in noisy surroundings. Thus in a quiet environment the microphones will be in surround mode in order that the user can hear sound from any direction. However , when in noise the microphones will focus so that sound can be picked up from where the user is looking, allowing speech to be heard above the noise.
Sudden loud sounds (such as a slamming door for instance) are dealt with instantly by the transient noise management system in Oticon Nera. This works in a fraction of a second to reduce gain and so avoid the sudden noise from becoming uncomfortable.
YouMatic is an automatic system that allows the sound processing systems within Oticon Nera to be personalised to the user’s individual needs across multiple sound environments. The individual systems, for example directionality, noise management, transient noise management etc. all work in harmony with the user’s needs.
AI or Artificial Intelligence Advanced is a system that allows the Oticon Nera hearing aids to react themselves to different sound environments. Conventional hearing aids will react in a fixed way to certain sound environments. Oticon Nera with its AI Advanced system will constantly adapt to changing environments and select the most favourable options to generate the best sound quality in any situation.
An 8 KHz bandwidth enables Oticon Nera to deal with a wide spectrum of sound.
Six fitting channels allow the amplification strategy within Oticon Nera to be configured to deal with a wide range of hearing losses.
Wind noise over the microphones can be annoying particularly for those users that enjoy an active outside lifestyle. The wind noise manager operates to suppress the effect of wind noise.
Most Oticon Nera styles feature binaural volume and program control. The hearing aids on each side communicate with each other so that any manual changes in volume or program are replicated on the other side. This ensures that both left and right aids are in perfect balance according to the loss in each individual ear.
Most Oticon Nera styles are Connectline enabled. This allows Oticon Nera hearing aids to connect to a range of Bluetooth equipped devices and accessories using a device called the Streamer Pro. For instance if the user has a Bluetooth equipped mobile telephone Streamer Pro allows sound from the phone to be streamed directly to the hearing aids. Not only that, but the sound is also corrected for the hearing loss. The phone can be in the pocket and the Streamer Pro worn round the neck. The phone rings and the user simply presses a button on the Streamer Pro to pick up the call. A microphone in the Streamer Pro relays the user’s voice back to the caller. The mobile phone remains in the pocket all the time. Other accessories can be used in conjunction with Streamer Pro as follows:
Streamer Pro can also be used as a remote control to facilitate manual adjustments of program or volume. Streamer Pro also contains a telecoil to allow the use of a loop system if available in a public building for instance.
Oticon has changed the way we think about hearing aids with the introduction of Oticon Opn - with help from the OpenSound Navigator™. With a wealth of new technology, your hearing is in good hands.
The Oticon Alta is known as ‘Oticon’s finest hearing aid’ and is one of the premium hearing aid families available today.
The Oticon Ria provides excellent sound quality, keeping sounds clear and crisp.
