You’ve just heard the same sentence four times: first as a healthy ear hears it, then as it reaches someone with mild, moderate and severe hearing loss. The voice doesn’t just get quieter: it gets less clear. And that is exactly what makes hearing loss so hard to recognise.
In my work I hear it every day: “I hear perfectly well, people just don’t speak clearly.” or “My son has such a quiet voice.” People with hearing loss often hear the voice but don’t understand the words. In this article I explain why this happens, how it gets there, and what you can do, starting today, to protect your ears.
What you just heard
In most cases hearing loss affects the high-pitched sounds first. It’s consonants like s, f, t, k that make speech clear: without them “fun” and “sun” sound alike, and a sentence turns into a puzzle.
- Mild hearing loss: you understand almost everything in quiet, but in a restaurant or on the phone it’s hard work. Many people don’t notice it.
- Moderate hearing loss: voices seem far away and “mushy”. You often ask people to repeat and turn the TV up.
- Severe hearing loss: without hearing aids a normal conversation becomes almost impossible.

How hearing loss happens
With age
With age, the tiny hair cells in the inner ear slowly wear out. This is called presbycusis (age-related hearing loss): it often starts after 50–60, always with the high tones, and progresses so slowly that you get used to it without noticing. That’s why, on average, several years pass before the first hearing check.
Noise, day after day
The sneakiest enemy is loud but “normal” noise: machines, traffic, music through headphones, bars. Damaged hair cells don’t grow back. A simple rule: above 85 dB (heavy traffic, a blender) the safe listening time gets much shorter, and every 3 dB more halves it. According to the WHO, over a billion young people risk hearing damage from listening at high volume.
Acoustic trauma
Sometimes a single event is enough: a firecracker nearby, a gunshot, a speaker at a concert. Afterwards your ear feels muffled or rings. It often goes away within a few hours, but it’s a warning sign: each time something gets damaged. If the muffled feeling or ringing lasts more than a day, or you suddenly hear much less in one ear, see an ENT doctor straight away: the sooner it’s treated, the better.
Protect your ears
- Earplugs at concerts and clubs. There are filtered earplugs that lower the volume without spoiling the music, ideal for musicians too.
- The 60/60 rule for headphones: no more than 60% volume, no more than 60 minutes at a time.
- Noise-cancelling headphones on the train or plane: that way you don’t have to turn the volume up to drown out the background noise.
- Distance from speakers and hearing protection at work, even when it’s “only for a moment”.
- Breaks: after a noisy evening, give your ears a few quiet hours.
5 habits for healthy hearing
- Enjoy the silence now and then. Your ears (and your brain) need breaks. Ten minutes without TV, radio or headphones, ideally outdoors, is a small daily gift.
- Respect your sleep. Your ears “listen” at night too: noise disturbs your rest. Don’t fall asleep with headphones at high volume; if you have tinnitus, a soft background sound is better than total silence (more on that here).
- Practise listening in “focus mode”. In a café or a square, try to pick out a single voice or sound and follow it for a minute. Look at the face of the person speaking and choose the right seat: with the noise behind you, not in front.
- Train your ear to recognise sounds. Recognising a bird’s song, an instrument in a song, the sounds of your home: it’s a real workout for the brain. As a sound engineer I can promise you: the ear can be trained, at any age.
- Get your hearing checked now and then. Just like your eyes: a hearing test every few years, and more often after 50 or if you work in noise.
