How loud live music gets
Sound is measured in decibels (dB). The scale is logarithmic, so every increase of about 3 dB roughly doubles the sound energy. Concerts and clubs often reach about 95 to 110 dB near the speakers, and sources vary on typical levels. That is loud enough to damage hearing in a short time.
How long is too long
A widely used workplace guideline from the US National Institute for Occupational Safety and Health (NIOSH) sets a recommended limit of 85 dB averaged over eight hours. For every 3 dB above that, the safe time halves. The chart below follows that rule. It is a rough guide for adults and can't predict the risk for any one person.
At typical concert levels, the daily guideline can be used up within the first part of a set. That is why ear protection matters even for a single show.
Choosing earplugs
Foam earplugs
Low cost and effective when rolled and inserted properly. They can make music sound muffled.
Reusable music earplugs
Often called high-fidelity earplugs. Filters lower the volume more evenly, so music sounds clearer.
Custom-molded plugs
Made from an impression of your ears by a hearing professional. Comfortable for frequent concertgoers.
Earmuffs for children
Children's ears need protection too. Well-fitting earmuffs are easier for young kids than plugs.
In the US, earplug packaging shows a Noise Reduction Rating (NRR). Real-world protection is often lower than the number on the box, mainly because of fit. Practice putting them in before the show, and follow the instructions on the package.
Habits that help
- Put earplugs in before the music starts, and keep them in.
- Stand away from the speakers. Even a few steps back can lower the level.
- Take breaks in quieter areas between sets.
- Give your ears a quiet day after a loud show.
- Try a sound level meter app to get a rough idea of how loud it is.
Ringing ears and muffled hearing
Ringing (tinnitus) or muffled hearing after a show is a sign your ears were exposed to too much sound. It often fades within a day or so, but repeated exposure can lead to lasting damage. If ringing or hearing loss lasts more than a day or two, see a doctor or audiologist. Sudden hearing loss in one or both ears needs medical attention as soon as possible.
Do earplugs ruin the sound of a concert?
Foam plugs can muffle music. Reusable music earplugs are designed to lower volume more evenly, so many fans find the sound clearer and less harsh than without them.
Are headphones after a show a problem?
Your ears benefit from rest after a loud show. Keep headphone volume low or skip them for the rest of the day.
