When your hearing suddenly seems dulled in one ear, it is natural to wonder what is behind it. Very often the answer is simple — a build-up of ear wax that is easily removed. But sometimes a muffled ear is the first sign of a change in your hearing itself. The two can feel remarkably similar, so here is how to tell them apart.
What wax blockage tends to feel like
Wax build-up usually announces itself fairly clearly. The classic signs are a sense of fullness or pressure, a blocked or "underwater" feeling, and hearing that is dulled rather than distorted. It often affects one ear more than the other, can come on over a few days, and may be accompanied by mild itching, a slight earache or even a ringing sound. Crucially, the change frequently arrives quite suddenly — one morning the ear simply feels stopped up.
- A feeling of fullness, pressure or blockage
- Sound that is muffled, as though through cotton wool
- Often worse in one ear than the other
- A relatively sudden onset over hours or days
- Sometimes ringing, itching or a mild ache
What genuine hearing loss tends to feel like
Age-related hearing change is usually the opposite of sudden. It creeps in gradually, over months or years, and typically affects both ears fairly evenly. Rather than a blocked sensation, people describe sounds as clear but harder to make out — particularly speech in background noise, or higher-pitched voices. You can hear that someone is talking; you just cannot quite catch the words. Turning the television up, asking people to repeat themselves and struggling in busy rooms are the everyday hallmarks.
The quick rule of thumb
As a general guide: a sudden, blocked, muffled feeling in one ear points towards wax, while a gradual loss of clarity in both ears — especially for speech in noise — points towards a change in hearing. But it is only a guide. Wax and hearing change can happen together, and the only reliable way to know is to have the ear looked at properly.
The good news is that telling the two apart takes minutes. We look inside the ear, and the picture is usually clear straight away.
How we tell for certain
At any STOTTS. practice we examine the ear canal with a video otoscope, so we — and you — can see exactly what is there on screen. If it is wax, a gentle microsuction earwax removal appointment clears it, often with immediate relief. If the canal is clear and your hearing still seems dulled, a full hearing assessment tells us what is really going on. Either way, you leave knowing the answer rather than guessing.
When to seek help sooner
Most blocked ears are nothing to worry about. But sudden hearing loss in one ear that does not settle, especially with dizziness, severe pain or discharge, should be treated as urgent — please contact your GP or NHS 111 promptly, as a small number of causes are time-sensitive. If in doubt, it is always worth asking.
