Closest to Natural

Closest to Natural

RONDO 3 is made for exceptional hearing performance, even in challenging listening environments. Automatic Sound Management 3.0 seamlessly adapts to any listening environment for optimal hearing and hands-free control. From busy offices to noisy restaurants, ASM 3.0 enables clearer, more comfortable hearing experience.

And by combining dual microphones and ASM 3.0 with MED-EL’s unique long arrays and FineHearing sound coding, RONDO 3 offers a sound quality no other single-unit processor can match. [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft]

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 your best hearing in any environment.
Wind Noise Reduction
Minimises 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.

Natural Loudness Growth 

Our Dual-Loop Automatic Gain Control instantly adapts volume levels to make loud sounds more comfortable and soft sounds easier to hear. With an extended loudness growth range and compression ratio (3:1), our loudness growth more closely follows natural loudness growth in the cochlea. [ft]

This is an advantage for loudness balancing with bilateral CIs, or if the other ear has natural hearing, such as single-sided deafness or for bimodal listening with a contralateral hearing aid.


Microphone Directionality

RONDO 3 uses two microphones with Microphone Directionality to mimic the natural pinna effect by reducing sounds behind and focusing to the front of the listener. This enables significantly better hearing performance in noisy environments.

Natural directionality provides significant advantage in everyday life, and Adaptive directionality provides a powerful boost in complex noise. [ft]


Complete Cochlear Coverage

In natural hearing, the nerve fibers of the spiral ganglion are tonotopically organized and extend the full length of the cochlea. If an electrode doesn’t cover two full turns (720°) of the cochlea, it can’t stimulate these nerve fibers to provide accurate pitch-place match.  

Our long, flexible arrays can be safely inserted all the way to the apical region to provide natural tonotopic stimulation across two full turns of the cochlea. With complete cochlear coverage, recipients can enjoy a natural pitch match from the very beginning. This enables significantly better hearing performance and a more natural hearing experience for your patients. [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft] [ft]

 

FineHearing Sound Coding

In nature, the cochlea uses two types of sound coding. Place-pitch tonotopic coding is used along the whole frequency range. In addition to 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 the sound below ~1000 Hz.

That’s why we created the only cochlear implant sound coding that mimics the natural time-coding for low frequencies and provides place-pitch match throughout the cochlea. By mimicking natural sound coding, FineHearing provides much more natural sound quality. [ft] [ft] [ft] [ft]

Anatomy-Based Fiting

Our default frequency allocation is designed to follow the natural tonotopic map of the cochlea. However, we know that one size does not fit all. This is why we are always striving to provide a closer match for each individual patient. Now, we are excited to be reaching closer to natural hearing than ever before with cochlear implants.

With our new anatomy-based fitting tools, you can easily fine-tune the frequency map of RONDO 3 to be closer to the natural map for each individual cochlea. By combining detailed imaging data from OTOPLAN with MAESTRO 9.0, you can now quickly assign center frequencies based on the actual anatomical location of each electrode contact. [ft] [ft] [ft]

Made for Bimodal

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 CI system and the hearing aid: pitch perception, loudness growth, and timing of a sound.

By combining these three elements, RONDO 3 offers the best solution for bimodal listening with practically any hearing aid.

017_R3_v006_01-5_R3-bk_per

Pitch Matching

Our long arrays and unique FineHearing technology provide the closest to natural pitch match of any CI, so we can provide a much closer match to the acoustic frequencies of the hearing aid. Other companies may use a bimodal fitting formula with frequency-shifting partial integration, which can compromise the performance of the hearing aid ear.

Our complete integration approach can offer a more natural frequency range and sound perception to both ears. This also lets you independently fit the hearing aid to best benefit, rather than using a bimodal fitting formula to correct for the CI.

Matched Loudness Growth

The natural loudness growth and 3:1 compression ratio of our proven dual-loop Automatic Gain Control makes it easy to balance with nearly any hearing aid—without having to drastically refit the hearing aid compression ratio. [ft]

This balanced front-end processing also means both the hearing aid and the audio processor can use any microphone directionality or beamformer settings without needing a wireless sync between devices. You can simply independently fit each device to best hearing benefit.

Compression Ratio

Synchronized Timing

Every hearing aid has an inherent processing delay, which is often longer than the processing time of the CI audio processor. This can cause a mismatch between the CI audio processing and the acoustic hearing aid. In turn, this timing mismatch would affect accuracy of inter-aural timing differences (ITDs).

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