Can Headphones Damage Hearing?
For many of us, headphones are a permanent fixture, on the commute, at the gym, or just to drown out background noise while we work.
They're convenient and, for the most part, harmless. But used the wrong way, headphones are one of the most common causes of preventable hearing loss, and because the damage builds up so gradually, most people don't realise it's happening until it's already done.
Understanding Safe Listening Levels to prevent hearing damage form Headphones
Hearing damage isn't just about how loud a sound is, it's about how loud and for how long. Sound is measured in decibels (dB), and the risk increases sharply as the volume climbs. Everyday conversation sits at around 60dB, which is considered safe for any length of time. Once you get above 85dB, however, damage becomes possible with prolonged exposure, and many people listen to music through headphones at 90–100dB or more without realising it.
To put that in context, a typical smartphone or portable music player is capable of producing sound well in excess of 100dB at maximum volume, loud enough to cause permanent damage in under 15 minutes of continuous listening. The general guidance is to keep the volume at around 60% of the maximum and to be mindful of how long you're listening for, particularly with in-ear headphones, which sit closer to the eardrum and can transmit sound more intensely than over-ear styles.
As a rough guide, it's generally considered safe to listen at:
85dB for up to 8 hours, roughly the level of heavy traffic or a busy restaurant kitchen.
95dB for no more than 4 hours, similar to a motorcycle engine at close range.
100dB for around 15 minutes, comparable to many personal music players at maximum volume.
The louder the sound, the shorter the safe exposure time, and these thresholds add up across the day, not just per listening session.
The 60/60 Rule
One of the simplest ways to protect your hearing while still enjoying your music is the 60/60 rule: listen at no more than 60% of the maximum volume, for no more than 60 minutes at a time. After an hour, give your ears a break before starting again.
This guideline exists because your ears need time to recover after sustained exposure to sound, even at moderate volumes.
Continuous listening without breaks doesn't give the delicate hair cells in your inner ear a chance to rest, and it's this cumulative strain, rather than any single listening session, that leads to long-term damage. If you find yourself needing to turn the volume up part-way through a long journey or workout, that's usually a sign of listening fatigue rather than a reason to increase the volume further.
A useful way to check whether your volume is too high is what's known as the "arm's length test": if someone standing an arm's length away can clearly hear what's playing through your headphones, it's likely loud enough to cause damage over time.
It's also worth remembering that the 60/60 rule is a general guideline rather than a hard limit.
Children and teenagers are more vulnerable to noise-induced hearing loss than adults, so it's worth being more cautious with listening time and volume for younger family members, and many devices now include built-in volume limiting features for this reason.
The Benefits of Noise Cancelling Headphones
One of the main reasons people turn the volume up in the first place is background noise, on public transport, in an office, or out and about. Noise cancelling headphones can make a real difference here, because they reduce the ambient sound around you rather than requiring you to drown it out.
Active noise cancellation uses built-in microphones to detect surrounding sound and generate an opposing sound wave that cancels it out, meaning you can listen comfortably at a much lower volume in a noisy environment than you would with standard headphones.
Over time, this can meaningfully reduce your overall noise exposure, particularly if you regularly listen to music or podcasts while commuting or travelling.
It's worth noting that noise cancelling isn't the same as noise isolation, which simply blocks external sound with a physical seal.
Both can help you listen at safer volumes, but active noise cancelling tends to be more effective against low, constant background noise, such as engine or traffic sound, so it's worth considering if you regularly find yourself increasing the volume to compensate for your surroundings.
That said, noise cancelling headphones aren't a licence to listen for longer. They reduce the need to listen loudly, but the 60/60 rule and regular breaks still apply, particularly if you're using them for several hours at a stretch while travelling or working.
Warning Symptoms to Watch For
Because headphone-related hearing damage develops so gradually, it's important to know the early warning signs and act on them rather than waiting for a routine check-up. These include:
Ringing, buzzing or hissing in the ears after listening, known as tinnitus, particularly if it lingers after you've taken your headphones off.
Sounds seemingly muffled or unclear for a period after listening, even in normal conversation.
Needing to turn the volume up more than you used to, to achieve the same level of clarity.
Difficulty following conversations in noisy environments, such as cafés or busy rooms.
A feeling of pressure, fullness or mild discomfort in the ears after extended headphone use.
Any of these symptoms occurring regularly is worth taking seriously.
Temporary threshold shift, a short-term dulling of hearing after loud exposure, is often an early warning that your ears are being pushed beyond a safe limit, and repeated episodes can contribute to permanent hearing loss over time.
If any of these symptoms clear up quickly after a listening session, it doesn't mean there's no cause for concern. Each episode of temporary threshold shift is a sign that your ears have been exposed to more sound than they can comfortably recover from, and it's the accumulation of these episodes, not any single one, that tends to cause lasting damage.
Protect Your Hearing Today
Headphones themselves aren't the problem, it's how they're used. Following the 60/60 rule, choosing noise cancelling options where possible, and paying attention to any warning symptoms can go a long way towards protecting your hearing for years to come.
If you've noticed any of the signs above, or simply haven't had your hearing checked in a while, there's no need to wait.
