Does Tinnitus Prefer One Ear? Exploring Ear Dominance, the Brain, and Ringing Ears

Tinnitus can feel like it’s playing favourites with one ear over the other, and for many people, one ear is indeed more affected than the other. But is this actually common? And if so, is there a scientific reason behind it? Let’s dive into what we know so far and explore if ear preference in tinnitus may be linked to our brain's left and right sides or other physiological factors.

Why Tinnitus Might Affect One Ear More Than the Other 

Most people think of tinnitus as a “head-wide” experience, but it’s often more complex. While tinnitus does occur in both ears for some, a large number of sufferers report that their ringing, buzzing, or hissing feels centred in a single ear or is significantly louder on one side. Some people may find that their tinnitus only affects one ear altogether. Here are a few factors researchers believe might influence this phenomenon:

1. Inner Ear Damage and Hearing Loss Tinnitus is frequently connected to damage in the inner ear’s hair cells, often from loud noises, ageing, or physical trauma. If one ear experiences more hearing damage than the other, it can make that ear feel more “tinnitus-prone.” For example, a musician who’s exposed to loud noises on one side could develop tinnitus stronger in that ear due to sustained exposure.
2. Ear Dominance and Neural Pathways While we know about handedness, there’s less discussion about “ear dominance.” Ear dominance refers to which ear processes sound with more sensitivity, sometimes due to the auditory nerve pathways and which hemisphere of the brain is more active in processing sound. Although left-handed people may have a “dominant” left ear, it’s not a hard rule—and tinnitus often disregards these kinds of assumptions.
3. Brain Hemisphere Functions Here’s where the brain gets involved. The left hemisphere typically handles language processing and detail, while the right side is more tuned into spatial awareness and holistic perception. However, there’s no clear evidence that this functional difference influences tinnitus in a way that makes one ear louder than the other. The “louder ear” in tinnitus may not directly reflect brain hemisphere differences.
4. The Connection Between Ear Dominance and Brain Activity While some experts have considered the possibility of a link between auditory dominance (or ear preference) and brain activity, we don't yet have strong evidence of a connection with tinnitus. Researchers are, however, exploring the idea that the brain regions responsible for processing sound may get disrupted differently on each side of the head, contributing to why tinnitus might seem more prominent in one ear. But this research is still emerging.

What Tinnitus Sufferers Say: Right vs. Left Ear
Though scientific studies are limited, anecdotal evidence suggests that people with tinnitus experience a range of symptoms across both ears. Many report that tinnitus is often louder in one ear, regardless of ear or hand dominance. Online forums are filled with reports of right-eared, left-eared, and both-eared tinnitus, each with unique stories.

So, Is Tinnitus “One-Sided” More Often Than Not?
Studies indicate that a large proportion of tinnitus sufferers feel it more acutely in one ear. Some potential contributors include:

• Uneven Hearing Damage: If one ear is more exposed to damaging environments, it can affect that ear more severely.
• Asymmetry in Ear Functionality: Minor differences in ear structures can contribute to how tinnitus presents in each ear.
• Neurological Factors: Ongoing studies are investigating whether disruptions in auditory processing are asymmetrical.

Join the Conversation: Share Your Experiences
Have you noticed that tinnitus favours one of your ears? Are you right-handed but hearing it stronger on your left side, or perhaps it’s the opposite? Many people find solace in connecting with others who experience similar symptoms, especially when there’s still so much mystery around why tinnitus behaves the way it does.
