How to Protect Your Hearing from Loud Noises
Noise-induced hearing loss is permanent — but entirely preventable. Here's what damages your hearing and what you can do about it.
By Alex Delooze · Delooze Hearing
Noise-induced hearing loss is one of the most preventable forms of hearing damage — and one of the most common. Unlike age-related change, which happens gradually over decades, noise damage can be caused by a single event or by cumulative exposure over years. Either way, once those hair cells in the inner ear are gone, they don’t come back.
The good news is that protecting your hearing is straightforward, and even small changes in habits can make a real difference over a lifetime.
How Noise Damages Hearing
The cochlea — the fluid-filled, spiral structure in the inner ear responsible for processing sound — is lined with thousands of tiny hair cells. These cells respond to vibration at different frequencies and convert it into electrical signals that the brain interprets as sound.
Loud noise causes intense vibration that physically damages these cells. Moderate noise exposure over a long period has the same cumulative effect. Once damaged, hair cells don’t regenerate. The hearing loss is permanent.
The first frequencies to go are typically the high ones — speech clarity, consonant sounds, birdsong. This is why people with early noise-induced hearing loss often say they can hear people speaking but struggle to make out what they’re saying.
How Loud Is Too Loud?
Sound is measured in decibels (dB). As a rough guide:
- Normal conversation: ~60 dB
- Heavy traffic: ~80 dB
- Power tools, lawnmower: ~90 dB
- Live music, nightclub: ~100–110 dB
- Gunshot, firework nearby: ~140–160 dB
Damage risk depends on both volume and duration. 85 dB is generally considered the threshold above which prolonged exposure causes damage. At 100 dB, damage can occur within minutes.
Common Sources of Damaging Noise
Headphones and earbuds — The 60/60 rule is a useful guide: no more than 60% of maximum volume for no more than 60 minutes at a stretch. In-ear earphones at high volume are particularly high-risk because the sound source is so close to the eardrum.
Work environments — Construction, manufacturing, farming, and some hospitality settings regularly exceed safe noise levels. UK law requires employers to provide hearing protection when noise regularly exceeds 85 dB. Know your rights and use the protection provided.
Live events — Concerts, festivals, and sports events often reach 100 dB or more. Distance from speakers helps significantly. Single-use foam earplugs are fine for one-off events; custom-filtered musician’s earplugs are worth considering if you attend live music regularly — they reduce volume without distorting sound quality.
Shooting and motorsport — Among the highest-risk activities. Appropriate protection (specifically designed for impulsive noise) is essential.
Practical Protection
Earplugs — Foam earplugs are inexpensive and effective for most situations. They’re not glamorous, but they work. For musicians, concert-goers, or anyone who wants to hear clearly while protecting their hearing, filtered or high-fidelity earplugs are a better option — they attenuate volume evenly across frequencies rather than muffling sound.
Custom protection — For regular use, custom-moulded earplugs fitted by an audiologist offer the best combination of protection, comfort, and sound quality. They’re made from impressions of your ear canals and last for years.
Take listening breaks — Stepping outside at a concert, or taking your headphones off for a while, gives the hair cells time to recover from temporary threshold shift — the precursor to permanent damage.
Distance — Doubling your distance from a speaker reduces the sound level significantly. Standing further from the stage or speakers at events is one of the simplest protective measures available.
Getting Your Hearing Checked
If you work in a noisy environment, play or attend live music regularly, or have any reason to think your hearing may have been affected by noise, a hearing test gives you a clear picture. Catching changes early means you can take action before they become significant.
At Delooze Hearing, we offer hearing assessments alongside custom hearing protection fitted to your ears. If you’re in a profession or hobby where your hearing is regularly exposed, it’s worth a conversation.
