Cochlear Implants for
Single-Sided Deafness

When you have hearing loss in one ear,
it's important to deliver sounds as naturally as
possible to match your hearing ear.

Full Range of Sound

Our cochleae are filled with tiny hair cells that correspond with specific tones or frequencies of sound. Think of your cochlea rolled across a piano keyboard. The high-pitched sounds, like birds chirping, activate the hair cells in the cochlea’s beginning, while the low-pitched sounds, such as dogs barking, activate deeper hair cells.[ft] [ft]

What does this mean for you?

The more access a cochlear implant electrode array has to your cochlea, the wider range of sound frequencies you could hear.

Other companies use shorter arrays that can only stimulate the first turn of the cochlea, sometimes marketed as "the hearing zone," which means that low pitched sounds will be heard in that ear as middle or high frequency sounds.[ft] [ft] 

At MED-EL, we don’t believe that a cochlear implant should stop at “good enough.” Our reliable cochlear implant systems and long electrode arrays offer you the widest range of sound and for your lifelong hearing journey.

Benefits of Hearing in Stereo
with a MED-EL Cochlear Implant

Even with “one good ear,” everyday life with single-sided deafness (SSD) can be exhausting. Listening with one ear takes a bigger mental toll when trying to separate what you want to hear from the background noise. This impacts your ability to follow conversations or tell where sounds are coming from.

We know that restoring the benefits of hearing in both ears is important for you to capture each moment the way it was meant to sound, with far less listening effort.[ft]   Thankfully, we designed our cochlear implants to use soft, flexible electrode arrays that are long enough to cover your cochlea to the fullest possible extent. An electrode long enough to reach the deeper, low pitched region is necessary to provide sound that is closest to natural hearing.
