Understanding Single-Sided Deafness Treatment Options

Single-sided deafness (SSD) means having little to no hearing in one ear while the other ear hears normally or near-normally. It affects more people than many realize, and it creates real challenges — difficulty locating where sounds come from, struggling to follow conversations in noisy rooms, and exhaustion from constantly positioning yourself to favor your hearing ear.

The good news is that there are effective treatment options available today.

What Makes Single-Sided Deafness Different

With two functioning ears, your brain uses subtle differences in timing and volume between each ear to locate sound and separate speech from background noise. When one ear isn't contributing, that system breaks down. People with SSD often report that noisy environments are particularly difficult, and that they feel mentally tired after conversations that others find effortless.

CROS and BiCROS Hearing Aids

CROS (Contralateral Routing of Signal) hearing aids are one of the most common solutions for SSD. A small microphone worn on the non-hearing ear picks up sound from that side and wirelessly transmits it to a hearing aid worn on the hearing ear. This means sounds coming from your "deaf side" are no longer lost — they're routed across so your brain can process them.

A BiCROS system works the same way but is designed for people who also have some degree of hearing loss in their better ear, combining amplification with signal routing.

Phonak offers a well-regarded option here — the Phonak CROS Infinio, which is compatible with the Audéo Infinio R hearing aids. It shares the same rechargeable design and IP68 water resistance as the hearing aid itself, and it connects seamlessly for reliable sound transmission throughout the day. ReSound Vivia also offers a CROS version of their microRIE model for those with single-sided deafness.

Bone Conduction Devices

Bone conduction devices work differently. Rather than routing sound through the ear canal, they transmit sound vibrations through the skull directly to the inner ear of the functioning side. These can be worn as a headband, attached to a soft band, or surgically implanted (known as a bone-anchored hearing aid, or BAHA).

Bone conduction options are often recommended when the non-hearing ear has structural issues that make wearing a traditional hearing aid difficult or impossible. A hearing evaluation helps determine whether this pathway is worth exploring.

Cochlear Implants

For some people with SSD, a cochlear implant in the non-hearing ear may be an option worth discussing with a specialist. Cochlear implants bypass the damaged parts of the inner ear and stimulate the auditory nerve directly. This is a surgical option and requires a referral and evaluation by an ear, nose, and throat physician (ENT) or cochlear implant center. It is not the right fit for everyone, but outcomes have improved significantly in recent years.

What About Doing Nothing?

Some people adapt to SSD over time and manage reasonably well, particularly in quiet environments. The challenge is that the brain works harder to compensate, and many people don't realize how much effort they're expending until they try a treatment option and notice the difference. There's no pressure to pursue treatment, but it's worth understanding what's available.

Over-the-counter hearing devices are not designed for SSD. Routing sound from one ear to the other requires precise programming and fitting — this isn't something a self-fitted device can accomplish effectively.

Getting the Right Fit

The first step with any of these options is a thorough hearing evaluation. Understanding the degree and type of hearing loss in each ear helps determine which solution is the best fit for your specific situation. From there, a hearing specialist can walk you through your options, including whether a CROS system, bone conduction device, or a referral for implant evaluation makes the most sense.
