Key
Damage builds up from loudness and listening time together
Volume
Around half of maximum, set in a quiet room
Breaks
After about an hour, give your ears a rest
Signs
Muffled hearing or ringing means it was already too much
Caution
Sudden hearing loss in one ear needs prompt medical care
Loudness and time add up
Long exposure to loud sound damages the hair cells in the inner ear that detect sound. These cells do not grow back once destroyed, so most noise-induced hearing loss is permanent. The key point is that damage accumulates with exposure time, not just loudness. One widely used workplace guideline is 85 decibels for eight hours a day, with the allowed time halving for every 3 decibels above that. In other words, a short burst of very loud sound and a whole day of moderately loud sound can put a similar strain on your ears.
Setting a volume rule
The actual loudness of earphones varies with the device and the earphones, so a single number is hard to give. The usual advice is to stay at or below about 60 percent of maximum volume and take a break after about an hour. Set the volume to a comfortable level in a quiet room; setting it somewhere noisy raises the baseline. Turning on your phone's hearing-protection volume limit or exposure tracking helps you keep an eye on your habits.

If the person next to you can hear your music, it is too loud
The trap of turning it up in noisy places
On a train or bus, background noise pushes you to keep raising the volume to hear the music. The total sound reaching your ears is then the noise plus the music, which adds up to a lot. In-ear earphones that seal well, or ones with noise cancelling, let you hear clearly at a lower volume and so protect your ears in the end. When walking or cycling, though, you need to hear your surroundings to stay safe, so use an ambient-sound mode or wear just one earbud.
Concerts, karaoke and gyms
Live venues, clubs, karaoke rooms and gyms that play music loudly put a heavy load on your ears even over a short time. To enjoy a show while protecting your hearing, you can use musicians' earplugs that reduce sound evenly; ordinary foam earplugs are still far better than nothing. Avoid standing right in front of the speakers, and step out somewhere quiet from time to time. If your ears feel muffled after a concert, avoid loud sound until the next day.
Warning signs from your ears
If, after loud sound, your ears feel muffled, you hear ringing or buzzing, or conversations seem far away, your ears have already gone past their limit. These symptoms often fade after a day or two, but repeated episodes can lead to damage that does not recover. Fading symptoms do not mean all is well; treat them as a warning and cut your exposure. Finding it harder to follow conversation in noisy restaurants can also be an early change, so do not brush it off.
When to see a doctor straight away
Suddenly losing hearing in one ear for no obvious reason may be sudden sensorineural hearing loss. Earlier treatment is associated with better recovery, so do not wait a few days to see — get to an ear, nose and throat doctor as soon as possible. Ear pain, discharge, severe dizziness, or ringing that has not settled after several days also need medical attention.

Children's and teenagers' ears
Children find it hard to judge when volume is too high, and their smaller ear canals can make the same setting louder at the eardrum. It is safer to give children volume-limited headphones or to cap the maximum volume on the device. Teenagers often spend much of the day with earphones in, so it is worth talking about both time and volume with them.
Everyday habits
Protecting your hearing depends more on small daily habits than on one big resolution. Building the items below into your routine protects your ears with little effort.
Set the volume somewhere quiet and do not go above it
Do not fall asleep with loud audio playing in your earphones
In noisy places, rely on isolation rather than volume
Take earplugs to concerts and big events
If you get ringing or muffled hearing, rest your ears that day
