Tinnitus explained
The sound only you can hear
Tinnitus is the perception of sound with no external source. Ringing, buzzing, hissing, whistling or roaring. It affects roughly 10 to 15 per cent of adults, and it is not imagined, not harmless to ignore, and not something you simply have to accept.
What is actually happening
Tinnitus is a brain signal, not an ear noise
The most common trigger is noise exposure. Loud sound damages the delicate hair cells inside the cochlea, which reduces the auditory signal reaching the brain.
The brain responds by increasing neural activity along those pathways, in much the same way you would turn up a radio with a weak signal. That increased activity is what you hear.
This is why tinnitus is so often described as being in your head rather than your ears, and it is why treatments aimed only at the ear so rarely help on their own.
What people describe
- Ringing, the most common description
- Buzzing or humming
- Whistling or hissing
- A roaring or rushing sound
- Sound in one ear, both ears, or centred in the head
- Constant, or coming and going in waves
Contributing factors
It is usually a combination
Tinnitus rarely has one clean cause. Most people we assess have two or three of these in play at once.
Noise exposure
Concerts, machinery, power tools, firearms, motorsport, headphones at volume, and military or emergency service careers. Damage accumulates quietly over years.
Age related hearing change
Natural change in the auditory system reduces input to the brain, and the brain compensates by raising its own gain.
Ear health
Wax blockage, middle ear infection, perforation, and inner ear conditions. Some of these are treatable, which is exactly why assessment comes first.
Stress and sleep
Stress does not cause tinnitus, but it reliably makes it louder and harder to ignore. Poor sleep does the same, and the two feed each other.
Jaw, neck and dental
Where tinnitus changes pitch or volume when you move your jaw, neck or head, the somatosensory system is involved. This is common and it is relevant to treatment choice.
Medications and stimulants
Some medications are known to be ototoxic. Caffeine, alcohol and nicotine do not cause tinnitus but frequently amplify awareness of it.
Most people we assess can point to two or three of these at once. Very few have a single clean cause.
Quiet rooms remove the competing sound. Stress activates the nervous system. Put those together at 11pm and tinnitus is the only thing left to listen to.
The cycle
Why it gets louder when you focus on it
The brain is a filter. It constantly decides what deserves attention and what can fade into the background. You stopped hearing your own fridge years ago.
When the brain classifies tinnitus as a threat, it does the opposite. It monitors the sound, checks in on it, and pulls it forward. Attention makes it louder. Louder makes it more distressing. Distress makes the brain monitor it harder.
Every program we run is built to interrupt that loop. That process has a name in the literature: habituation. It is not acceptance, and it is not masking. It is the brain reclassifying the signal as unimportant so it stops surfacing it.
Get it checked
When tinnitus needs prompt attention
Most tinnitus is not dangerous. These situations are the exceptions, and they warrant seeing a doctor promptly rather than waiting.
Sudden onset
Tinnitus that appears suddenly, particularly alongside a sudden drop in hearing.
One ear only
Tinnitus clearly confined to one ear, especially if it is new.
Pulsing in time with your heartbeat
Pulsatile tinnitus should always be investigated.
With dizziness or vertigo
Balance symptoms alongside tinnitus need a medical assessment.
With ear pain or discharge
These point to something treatable that should be dealt with first.
Any significant change
A clear change in character, side or severity is worth checking.
The part most people are not told
Tinnitus does not have to get worse with age
It is one of the most common things people are told, and it is not supported by the evidence. With structured management, most people find tinnitus becomes less intrusive over time, not more. What changes is not the signal. What changes is how much of your attention it takes.
Common questions
What people ask about tinnitus
Is tinnitus a sign something is seriously wrong?
In the large majority of cases, no. Tinnitus is usually the auditory system compensating for reduced input, not a symptom of disease. The exceptions matter though: sudden onset, tinnitus in one ear only, a pulse in time with your heartbeat, or tinnitus with dizziness or sudden hearing loss all warrant prompt medical assessment rather than waiting.
Why can I hear it when nobody else can?
Because the sound is being generated inside your auditory pathway rather than arriving from outside it. There is no acoustic signal in the room for anyone else to pick up. This is also why it does not show up on a standard hearing test, and why being told your hearing is normal is not the same as being told nothing is wrong.
Does everyone hear the same thing?
No. Ringing is the most common description but people report buzzing, hissing, whistling, roaring, crickets, static and pulsing. It can sit in one ear, both, or feel like it is in the middle of the head. It can be constant or come in waves. All of these are tinnitus.
Will hearing aids fix it?
Amplification helps a lot of people, because restoring input to the auditory system reduces the brain's need to compensate. It is not a complete answer on its own. Plenty of patients arrive already wearing well fitted aids and still finding tinnitus intrusive, which is usually the point at which a structured program makes the difference.
Can children get tinnitus?
Yes, though it is less commonly reported because children often do not think to mention it. If a child describes a sound nobody else can hear, it is worth a hearing assessment rather than dismissal.
Is it caused by stress?
Stress does not create tinnitus, but it reliably makes it louder and harder to ignore, and tinnitus in turn raises stress. That loop is one of the main things our programs are built to interrupt.
