Updated October 2026 · Levels and metering explained
Long exposure to loud sound can damage hearing, and audio work often means hours of listening. Keep headphone levels moderate, take regular breaks, and check your hearing if you notice ringing, muffling or changes that last. A quiet listening level is also more accurate for making decisions about balance and tone.
Audio work involves a great deal of listening, and much of it happens on headphones at close range. A level that feels comfortable for a few minutes can still add up to harm over a long session, and the damage to hearing is often gradual and hard to notice. Protecting your hearing is part of protecting your work, because a fatigued ear makes poor decisions about balance and tone.
This post explains how exposure adds up, how to set a safe level for mixing and recording, how to take breaks and what to do if your hearing changes.
Hearing damage depends on both the level and the duration of exposure. A higher level causes damage more quickly, and a longer session adds more exposure. The damage can build over many sessions, and it is not always reversible. Many people do not notice the early changes, because the ear adapts to a loud level and makes it feel normal.
Headphones are particularly close to the ear, so a moderate-looking level can be significant. Check your listening level with a meter if your software offers one.
A common approach is to mix and record at a moderate level, where speech is clear and comfortable without strain. Many professionals work quietly most of the time, and turn up only briefly to check a specific detail. If you find yourself turning up to hear the mix, the mix may need adjusting rather than more volume.
A moderate level also gives better judgement. At high volume, the ear emphasises the bass and changes the balance of tone, and it tires quickly. A quieter level reveals the true balance of the mix, and it lets you judge the voice and the detail more clearly. Mixing at a lower level is good practice as well as protection.
Step away from the headphones at regular intervals, especially during long sessions. A break of a few minutes every hour gives the ear time to recover, and it helps you come back with fresh judgement. Many people find that a break makes problems easier to hear when they return.
Speakers can be used for a large part of the checking, at a moderate level, with the room providing a more natural sound. Headphones are still valuable, especially for detail, but a mix of speakers and headphones at low to moderate levels is kinder to the ear.
Ringing in the ears, a muffled sound after a session, or a sense of fullness that lasts after you stop listening are warning signs. So is any change in hearing that persists for more than a short time. If you notice these, reduce your listening level and rest your ears. If the changes continue, see a doctor or an audiologist.
A simple habit protects both your ears and your judgement: decide the listening level before you start, and write it on a note near the desk. Keep the volume at that level for the whole session, and check the mix at a second, lower level during the final decisions. The lower level exposes balance problems that a loud level hides, and it keeps the ears fresh. Give the ears a few minutes of silence between checks, and the next decision will be clearer. Silence is not wasted time; it is part of the work. Plan that silence into the session, rather than leaving it to chance, and treat it as a deliberate part of the routine.
Consider a rule for the end of the session as well. When the ears feel tired, stop mixing and do the administrative work instead. Tired ears make decisions that you may regret the next day.
General guidance cannot replace a professional assessment of hearing. Hearing needs differ between people, and some are more sensitive than others. If you have concerns about your hearing, speak to a doctor or an audiologist, and treat any lasting change as a reason to seek advice.
Good decisions come from a comfortable level. The LUFS meter helps check the loudness of a finished file, so you do not need to turn the volume up to judge it. The Vocal Checker shows clipping, noise and level problems in a recording you own. For the balance between checking and comfort, read the voice-over loudness post in this series.

Moderate, where speech is clear and comfortable. If you have to turn up to hear, the mix may need adjusting.
It gives more accurate judgement of balance and tone, and it protects your hearing.
A few minutes every hour in long sessions is a good habit.
Reduce the level and rest. If the ringing or muffling lasts, see a doctor or audiologist.
