Hearing Aids for Single-Sided Deafness

When you can only hear well in one ear, everyday life can start to feel uneven and tiring.

Simple things like talking in a group, crossing a busy street or following a conversation in a restaurant may suddenly take much more effort. You may find yourself guessing where sounds are coming from or feeling worn out by the end of the day.

Hearing aids for single-sided deafness are designed to work with your stronger ear, so you do not have to work as hard just to keep up.

They use different ways of picking up sound on your weaker side and sending it where you can hear it best. So, what hearing aids can help with single-sided deafness?

What is Single-Sided Deafness?

Single-sided deafness means a person has little to no hearing in one ear. The other ear may hear normally or have much better hearing. Many people first notice challenges when sounds come from the side with hearing loss.

It can also be harder to tell where sounds are coming from. Busy restaurants, meetings and social gatherings may feel different because voices and background noise come from several directions.

The experience varies from person to person, but it can affect conversations and listening situations.

Why the Brain Has Trouble Locating Sound with Hearing on One Ear

Why the brain has trouble locating sound with hearing on one ear comes down to how people normally determine where sounds originate. When both ears hear a sound, the brain compares small differences in timing and loudness between each ear.

Those differences help identify whether a sound is coming from the left, right, front or behind. With hearing in only one ear, the brain has less information available for making those comparisons.

As a result, it can be harder to tell where a voice, alarm, vehicle or other sound is coming from.

Some people notice this most in busy environments where several sounds are happening at the same time. Others become aware of it when someone speaks from a side they weren’t expecting.

Common Hearing Aid Setups Used for Single-Sided Deafness

Several hearing aid setups are used to address the unique listening challenges associated with single-sided deafness. The options below work in different ways and may be recommended based on hearing levels, anatomy and individual listening needs.

These can include:

• • CROS systems that send sound from the non-hearing ear to the better-hearing ear.
  • BiCROS systems that route sound from one side while also providing amplification in the better-hearing ear.
  • Bone conduction devices that transmit sound through vibrations in the skull rather than through the ear canal.
  • Cochlear implants for certain individuals with severe hearing loss in one ear.

Important Features to Look for in Hearing Aids for Single-Sided Deafness

Because hearing is limited on one side, some devices are built to route sound from the poorer-hearing side to the better-hearing ear.

Wireless connectivity may also be a consideration for people who regularly use phones, televisions and other audio devices. Comfort, battery life and ease of use can become important when hearing aids are worn for long periods each day.

Some people also pay close attention to how discreet a device looks and how easily settings can be adjusted. The features that stand out most often reflect the listening situations, communication needs that are part of a person’s life.

Questions to Ask an Audiologist About Single-Sided Deafness Options

Single-sided deafness can involve different treatment options, so it helps to ask questions that connect directly to daily listening needs. Before choosing a device or setup, these questions can guide the conversation with an audiologist:

• What type of single-sided hearing loss do I have?
• Which options match my hearing test results?
• How would each option handle sound from my poorer-hearing side?
• What should I expect in restaurants, meetings or group settings?
• How much adjustment time is typical with this setup?
• What maintenance, follow-up care or accessories would be involved?

Taking the Next Step Toward Easier Everyday Hearing

Single-sided deafness isn’t always obvious to the people around you, but it can change the way you move through everyday situations. A crowded restaurant, a conversation in the car or someone calling your name from another room may feel different than they once did.

That’s why hearing solutions for single-sided deafness focus on the unique challenges that come with relying on one ear. The right approach isn’t necessarily about hearing more. It’s often about making every day listening feel less frustrating and less unpredictable.
