"Can I get just one hearing aid?"
This is one of the questions I get asked most often in my practice, usually followed by "My left ear is perfectly fine" or "It would be cheaper." The answer is not as simple as one might imagine.
As an audiologist, I've seen how this decision influences not only hearing but also safety, relationships, and quality of life. Let's explore together what's really at stake when you hesitate between one or two hearing aids.
Understanding Unilateral Hearing Loss
True unilateral hearing loss (Single-Sided Deafness, or SSD) means you hear normally in one ear and less well in the other. This is different from asymmetrical hearing loss, where both ears are affected, but to different degrees.
Here's what many people don't realize: even if only one ear is affected, the impact on your daily life can be considerable. Your brain needs information from both ears to:
Locate the source of sounds
Understand speech in noise
Create a complete "sound image" of your environment
Reduce listening effort
When one ear isn't doing its part, your entire auditory system has to compensate, much like watching a 3D movie with one eye closed.
How do you know if it's really just one ear?
Many patients come in convinced that they only have hearing loss in one ear, but tests often reveal that both ears are affected. Here's why this confusion is so common:
The better ear compensates. If your right ear has a mild loss and your left ear has a moderate loss, you might believe the right ear is "normal" simply because it's doing most of the work.
Gradual changes go unnoticed. When hearing loss develops slowly over several years, people adapt without realizing it. Your "good" ear may not be as good as you think.
Your phone habits speak volumes. Do you always hold the phone to the same ear? This is often the first sign of asymmetrical hearing.
A professional evaluation is essential. Only a comprehensive hearing test can determine if you have unilateral loss or asymmetrical loss in both ears. Many people are surprised by their results.
The Hidden Difficulties of Unilateral Hearing Loss
The impact of unilateral hearing loss on daily life is often underestimated. Here are the difficulties that surprise my patients the most:
The "head shadow" effect. High-frequency sounds (like speech consonants) don't travel well around the head. If someone speaks to you on the side of your bad ear, you'll hear their voice but won't understand the words. It's like listening to a poorly tuned radio station.
Exhausting social situations. Constantly positioning yourself so your good ear faces the speaker is tiring, both mentally and physically. Many people end up with neck pain from constantly turning their head. Choosing a seat in a restaurant becomes a matter of strategy rather than conviviality. You always end up taking the same seat, not next to your loved ones, but across from them.
Important sounds you miss. You might not hear:
Someone calling you from the side of your deficient ear
A car approaching from that side
Your alarm if you sleep on your good ear
Warning signals at work or in public spaces
Difficulties in noise. Restaurants, parties, and meetings become particularly trying. Your brain cannot rely on binaural processing to separate speech from background noise. It's like trying to follow a conversation at a cocktail party with an earplug in one ear.
When a Single Hearing Aid is Justified
There are situations where wearing a single hearing aid is perfectly appropriate:
Total unilateral deafness, with one ear completely non-functional. Conventional hearing aids cannot help an ear with no residual hearing.
Medical contraindications on one side, such as chronic discharge, absence of an ear canal, or certain pathologies that prevent the wearing of a hearing aid.
Temporary conductive hearing loss on one side. If an effusion or infection is expected to resolve, a single hearing aid for the other ear may be a temporary solution.
Note: Some people ask to buy only one hearing aid for financial reasons, but CLARIA hearing aids are sold in pairs to ensure optimal hearing support when both ears need it.
Why Two Hearing Aids Are Generally Better
When both ears have aidable hearing loss, wearing two hearing aids provides spectacular benefits:
Better speech understanding in noise. Studies show that binaural fitting improves speech recognition by up to 40% in noisy environments. This is the difference between nodding politely and actually participating in the conversation.
Better sound localization. You know where sounds are coming from, which improves your safety and awareness. This isn't just comfort: it's about hearing a car horn or knowing which of your grandchildren is calling you.
Less listening effort. Your brain no longer needs to strain, which reduces the exhaustion associated with listening tension throughout the day. Imagine ending the day with energy instead of a headache.
Better sound quality. Music sounds fuller, conversations more natural, and the world regains its depth. The difference is a bit like going from AM radio to surround sound.
Prevention of auditory deprivation. An unaided ear with hearing loss can lose speech understanding over time due to lack of stimulation. The principle of "use it or lose it" also applies to hearing.
Lower volumes. Two hearing aids working together require less amplification than a single one trying to compensate for both ears. The result: more comfortable listening and less whistling.
The Real Cost of Choosing a Single Hearing Aid
Here's what choosing a single hearing aid actually means when two are needed:
At the restaurant: You will continue to struggle, as your brain cannot effectively separate speech from noise with only one aided ear. Romantic dinners remain stressful instead of romantic.
During family gatherings: You will miss conversations happening on the unaided side and constantly ask people to repeat themselves. Half the room becomes a dead zone.
For your safety: You will not reliably locate sounds and risk missing an alert or an approaching vehicle. That motorcycle coming on your left? You might not hear it.
At work: Participating in meetings remains difficult, especially in rooms where you are surrounded by colleagues. Your career progression suffers when you cannot fully engage.
In the long run: Your unaided ear continues to degrade, which can make future treatments less effective. You are gambling with your future hearing.
Specific Solutions for Unilateral Deafness
If you genuinely have one deaf ear and one normal ear, conventional hearing aids will not be able to help the deaf ear. However, there are dedicated solutions:
CROS hearing aids pick up sound from the deaf side and transmit it to the good ear. They correct the head shadow effect and improve alertness.
BiCROS systems work on the same principle but also amplify sound for the better ear if it also has hearing loss.
These systems improve environmental awareness but do not restore true directional hearing. They are compromise solutions for a very specific problem.
The Budget Question
I understand the financial concern. With traditional hearing aids costing $4,000-$7,000 a pair, it's natural to try to reduce the bill. But consider this:
With CLARIA's pricing for complete pairs:
Atom One: $98/pair
Atom 2: $189/pair
Atom Pro 2: $289/pair
Ion: $489/pair
Ion Pro: $689/pair
These affordable prices for complete pairs allow you to avoid any compromises.
You benefit from all the advantages of binaural hearing: 40% better speech understanding in noise, the safety provided by directional perception, and reduced auditory fatigue. Investing in correct hearing costs less than many monthly expenses we don't even think about.
The Science of Binaural Hearing
Your brain is designed to process sound from two ears. This binaural processing allows you to:
Filter noise naturally. Two ears help your brain focus on what you want to hear while filtering out background noise.
Localize sounds instantly. The tiny time delay between sound arriving at each ear tells your brain exactly where it's coming from.
Hear with less effort. Just as using both eyes reduces eye strain, using both ears reduces auditory fatigue.
Maintain spatial awareness. You operate in a 360-degree sound environment. A single hearing aid only offers you 180.
Concrete Situations: One Hearing Aid vs. Two
Here's the difference in practice:
Situation: Driving
One hearing aid: You risk not hearing an emergency vehicle approaching from the unaided side
Two hearing aids: Complete perception of your sound environment, for safe driving
Situation: Dinner at a restaurant
One hearing aid: You still struggle, unable to separate speech from noise
Two hearing aids: 40% better speech understanding, and the rediscovered pleasure of conversation
Situation: Walking in the city
One hearing aid: Important sounds escape you on one side, your safety is reduced
Two hearing aids: Complete environmental awareness, confident movement
Situation: Family reunion
One hearing aid: You constantly reposition yourself to hear and miss side conversations
Two hearing aids: Natural participation, no matter your place at the table
The Professional's Perspective
After years of fitting patients, here's what I've observed:
Patients who need two hearing aids but try to manage with only one almost always encounter the limitations of this solution. They quickly realize that a partial improvement in hearing is not enough in real life.
Those who get two hearing aids when they need them adapt faster, report greater satisfaction, and participate more fully in life. The difference is clear and consistent.
With CLARIA's accessible prices for complete pairs and a 45-day trial, you can experience complete hearing improvement without any risk. Advanced features like the Ion Pro's six hearing profiles or the Atom Pro 2's background noise suppression perform at their best when both ears are aided.
Making Your Decision
Ask yourself these questions:
Has a professional evaluation confirmed that my hearing loss affects only one ear?
Do I struggle in noisy environments?
Is directional hearing important for my safety and lifestyle?
Am I willing to accept the limitations of monaural hearing?
If you have hearing loss in both ears, even if one ear is more affected than the other, two hearing aids will serve you better than one. The brain needs information from both ears to function optimally.
Key Takeaway
"One ear or two?" The real question isn't about your ears, but about your brain. Your auditory system is designed to work with two inputs. When both ears have hearing loss, fitting only one is like wearing a monocle instead of glasses: you'll see better than without, but you'll always miss half the picture.
With CLARIA's revolutionary prices, starting at just $98 a pair, the financial barrier to binaural hearing has practically disappeared. Whether you choose the discretion of the Atom range or the power of the Ion range, with features like Bluetooth streaming and multiple hearing profiles, you benefit from complete hearing support.
Don't compromise on your hearing, your safety, and your quality of life. Your brain, your loved ones, and your future self will thank you for choosing complete hearing rather than a half-solution.
Take advantage of CLARIA's 45-day satisfaction guarantee to discover all the benefits of correct fitting in your daily life. Because when it comes to hearing, two isn't just twice as good as one: it's incomparably better. And with CLARIA's affordable pairs, better hearing is finally within reach for everyone who needs it.
