Noise-induced hearing loss is one of the few kinds of hearing damage that’s almost entirely preventable — and one of the easiest to ignore, because it happens gradually and painlessly, long before you notice anything’s changed.
How loud is too loud?
As a rough guide, sustained exposure above about 85 decibels — roughly the level of heavy traffic or a loud vacuum cleaner — can damage hearing over time. Concerts, clubs, power tools, motorbikes and loud headphone use all regularly exceed that. It’s not usually one loud moment that causes the damage; it’s repeated exposure, day after day or year after year, that adds up.
Who’s most at risk
- Anyone working regularly around loud machinery, tools, or music
- Frequent gig, club or festival-goers
- Motorbike riders and those who shoot or hunt regularly
- People who listen to headphones at high volume for long periods
The early warning signs
Noise damage rarely announces itself loudly. The early signs are subtle: ringing or muffled hearing after a loud event that takes a day or two to settle, struggling to follow conversation in noisy rooms, or turning the TV up a little more than you used to. Any of these, especially if they’re becoming a pattern, is worth having checked.
Hearing loss from noise doesn’t hurt, which is exactly why it’s so easy to miss until it’s already happened.
What actually protects you
Simple, consistent habits make the biggest difference: turning the volume down before it’s uncomfortable, taking breaks from continuous loud noise, and wearing proper hearing protection where it’s needed — off-the-shelf earplugs for occasional use, or custom-moulded protection if you’re exposed regularly. A baseline hearing test is also worth having if you’ve had years of exposure, simply so you know where you stand and can track any change going forward.
The damage is permanent once it happens — but almost all of it is avoidable with a bit of awareness beforehand.
