Noise-induced hearing loss is permanent, painless and gradual, which is why it’s easy to ignore. The good news: it is almost entirely preventable. You don’t need to give up loud music — you just need to understand how volume and time work together.
How hearing damage happens
Inside your inner ear are thousands of tiny hair cells that turn vibrations into nerve signals. Very loud sound, or loud sound for a long time, damages them. Unlike many cells in the body, these hair cells do not grow back. Damage usually starts at high frequencies, so speech in noisy places becomes harder to follow long before you notice anything else.
How loud is too loud?
Sound level is measured in decibels (dB). Because the scale is logarithmic, every +3 dB doubles the sound energy — and roughly halves the time you can safely listen.
| Sound level | Example | Approximate safe daily exposure* |
|---|---|---|
| 60 dB | Normal conversation | No limit |
| 70 dB | Vacuum cleaner, busy office | No limit for most people |
| 85 dB | Heavy traffic, loud restaurant | 8 hours |
| 88 dB | Lawn mower | 4 hours |
| 94 dB | Loud headphones, motorbike | 1 hour |
| 100 dB | Nightclub, headphones near max | 15 minutes |
| 105–110 dB | Rock concert near the stage | Under 5 minutes |
| 120 dB+ | Sirens, fireworks up close | Immediate risk |
*Based on the widely used occupational guideline of 85 dB(A) for 8 hours with a 3 dB exchange rate. The World Health Organization’s safe-listening guidance for personal audio is more conservative for weekly exposure. Individual sensitivity varies.
The 60/60 rule
A simple, memorable guideline for headphones: listen at no more than 60% of maximum volume for no more than 60 minutes at a time, then give your ears a break. It isn’t precise — headphones vary a lot in loudness — but it keeps most people in a safe zone.
If someone an arm’s length away has to shout for you to hear them, or can clearly hear your music from your headphones, it’s too loud.
Headphone habits that protect your ears
- Use noise cancelling or well-sealing earphones. When outside noise is blocked, you naturally listen quieter. On a train or plane, people often turn music up 10–15 dB to drown out noise.
- Turn on your phone’s hearing features. Most phones can show your weekly headphone exposure and automatically reduce loud audio.
- Set a volume limit for children’s devices and choose volume-limited kids’ headphones.
- Take breaks. Even 5–10 minutes every hour helps your ears recover.
- Turn it down after a loud day. If you’ve been at a concert or a noisy workplace, give your ears a quiet evening.
Concerts, clubs and festivals
- Wear musician’s earplugs. These high-fidelity earplugs reduce volume evenly (by around 10–25 dB) so music still sounds clear, unlike foam plugs that muffle it.
- Keep your distance from speaker stacks and take breaks in quieter areas.
- Use a phone decibel app to get a rough idea of the level around you.
Home listening and home studios
Speakers in a room are generally less risky than headphones, but home theaters and studios can get loud. For mixing music, many engineers work at moderate levels around 75–85 dB SPL, which is also kinder on the ears over long sessions. Turn the volume down before switching sources, and never start playback with the volume at maximum.
Warning signs
- Ringing, buzzing or hissing in your ears (tinnitus) that lasts after loud exposure
- Muffled hearing after a concert that doesn’t clear within a day
- Difficulty understanding speech in noisy places
- Needing the TV or music louder than other people
- Sounds that feel painfully loud (hyperacusis)
A hearing test is quick and painless. An audiologist can also make custom-moulded earplugs or in-ear monitors.
Frequently asked questions
Are earbuds worse for hearing than over-ear headphones?
Not inherently — what matters is the volume level reaching your ear. But earbuds that don’t seal well let in noise, so people tend to turn them up louder. A good seal or noise cancelling helps.
Does temporary ringing after a concert mean damage?
It’s a sign your ears were exposed to harmful levels. Even if it fades, repeated exposure can lead to permanent damage. Use earplugs next time.
Is bone conduction safer?
Bone conduction headphones still deliver sound to the inner ear, so the same volume limits apply. Their main advantage is keeping you aware of your surroundings.
