Closest to Natural Hearing

By combining dual microphones, ASM 3.0, MED-EL’s flexible electrodes and FineHearing sound coding, SONNET 3 provides superior sound quality that no other cochlear implant manufacturer can match. [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft]

Even in challenging listening environments, SONNET 3 users can experience exceptional hearing performance. Thanks to Automatic Sound Management 3.0, SONNET 3 seamlessly adapts to any listening environment, providing your patients optimal hearing and hands-free control. ASM 3.0 enables clearer, more comfortable hearing experiences even in busy offices or noisy restaurants.

Microphone Directionality

 

Two microphones reduce noise from behind and focus on sounds to the front for significantly better hearing in noise. [ft]

Automatic Volume Control

 

Dual-Loop Automatic Gain Control instantly adapts volume levels to make loud sounds more comfortable and soft sounds easier to hear.

Ambient Noise Reduction

 

Reduces continuous ambient noise—such as a desk fan—for easier, clearer listening.

Adaptive Intelligence

 

Intelligently adapts front-end processing to changing listening environments for the best hearing in any environment.

Wind Noise Reduction

 

Minimizes continuous wind noise for improved listening in outdoor environments.

Transient Noise Reduction

 

Instantly attenuates sudden loud noises, like a vacuum cleaner or clattering dishes, for comfortable listening.

Fitting With Any Hearing Aid

MED-EL cochlear implants are designed to provide a closer to natural match with any hearing aid. There are three main components that should match between the cochlear implant system and a hearing aid: pitch perception, loudness growth, and timing. By combining these three elements, SONNET 3 offers an ideal solution for bimodal listening with practically any hearing aid.

With Bimodal Synchronization, you can easily match the processing delay timing between SONNET 3 and nearly any hearing aid, without needing to refit the hearing aid. This more natural timing match can help support better sound localization with SONNET 3 and a hearing aid. [ft] [ft]

Natural Sound Quality with FineHearing

In nature, the cochlea uses two types of sound coding. Place-pitch tonotopic coding is used along the whole frequency range. Along with place-pitch coding, low-frequency sounds are also coded by rate. With this time coding, the frequency of nerve signals is synchronized to the frequency of sounds below ~1000 Hz.

Only MED-EL cochlear implants use sound coding that mimics the natural time coding for low frequencies, providing users place-pitch match throughout the cochlea. By mimicking natural sound coding, FineHearing provides much more natural sound quality.[ft] [ft] [ft] [ft]


Anatomy-Based Fitting

One size does not fit all. This is why we strive to provide a closer match for each individual patient. Reaching closer to natural hearing than ever before with cochlear implants may now be possible with Anatomy-Based Fitting.

With just a few clicks, you can import the detailed electrode location data into MAESTRO 11 or later from OTOPLAN for place-based mapping. MAESTRO automatically calculates an optimal distribution of electrode center frequencies to cover the full input frequency range (70Hz–8,500 Hz). At the same time, it also aligns each center frequency to the natural tonotopic map as closely as possible based on where each contact is positioned in the cochlea. You can also fine-tune the frequency range of each electrode contact using the simple manual controls.

“Methods to minimize electric mismatches, such as place-based mapping procedures, may support better early speech recognition for [similar patient populations of EAS users].”

Dillion et al., 2023

“ABF can be used to fit experienced bilateral cochlear implant users; it improves speech perception, especially in noise, and self-perceived sound quality. ABF fitting is a promising approach to match the input from both CIs, thereby providing access to binaural processing.”

Kurz et al., 2023
