How to protect your hearing as a live sound engineer

2026-10-14 · 10 min de lectura

Control both level and time: NIOSH recommends staying below 85 dBA averaged over eight hours and halving the time for every 3 dB more. Use flat-attenuation earplugs, ideally custom-fitted, measure your exposure, get regular hearing tests and see an audiologist if you notice tinnitus or hearing loss.

Your ears are the tool you are paid for. As a live sound engineer you spend long days on load-ins, line checks, soundchecks and shows at high levels, and noise-induced hearing damage usually builds up without pain or warning. By the time you notice it, it is often permanent.

This guide is written for engineers working in the United States and the United Kingdom. It summarises what OSHA, NIOSH, the UK Health and Safety Executive (HSE) and the World Health Organization (WHO) say about noise exposure, what the research says about people who do your job, and how to turn that into a routine: earplugs, hearing tests, tinnitus and measurement.

This is not medical advice. Any symptom or doubt about your hearing should go to an audiologist, an ENT doctor or your GP.

How loud is too loud for a live sound engineer?

Risk depends on two things at once: level and time. NIOSH, the US federal research agency for occupational safety, recommends keeping worker exposure below the equivalent of 85 dBA over eight hours, with a 3 dBA exchange rate. That means every 3 dB increase halves the time you can safely spend at that level.

Applied as simple arithmetic, that rule gives 88 dBA for four hours, 91 dBA for two hours and 94 dBA for one hour. A show averaging close to 100 dBA at front of house uses up a full day's dose in minutes, not hours. And the dose adds up across the day: the load-in, the soundcheck, the support act, the headline set and the bar after the show all count.

For audiences, the WHO published a global standard for safe listening venues and events. Its first recommendation is to limit average sound levels to 100 dB (LAeq over 15 minutes), alongside monitoring levels, optimising venue acoustics and sound systems, making hearing protection available, providing quiet zones and training staff.

What do OSHA and the UK Noise at Work Regulations require?

The legal limits are less strict than the NIOSH recommendation, and they differ between countries.

Rule	Daily level	What it triggers
OSHA (US) permissible exposure limit	90 dBA, 8-hour TWA, 5 dBA exchange rate	Legal maximum for general industry
OSHA action level	85 dBA, 8-hour TWA	Employer must run a hearing conservation program
NIOSH (US) recommendation	85 dBA, 8 hours, 3 dBA exchange rate	Recommended exposure limit, not a law
UK lower exposure action value	80 dB(A) daily or weekly	Risk assessment, information and training
UK upper exposure action value	85 dB(A) daily or weekly	Hearing protection and hearing protection zones
UK exposure limit value	87 dB(A), taking hearing protection into account	Must not be exceeded

In the US, OSHA's standard 29 CFR 1910.95 says the baseline audiogram must be established within six months of an employee's first exposure at or above the action level, and repeated at least annually after that. Its duration table allows 4 hours a day at 95 dBA and 2 hours at 100 dBA, which is far more permissive than the NIOSH curve.

In Great Britain, HSE explains that the Control of Noise at Work Regulations 2005 came into force for most sectors in 2006, but only on 6 April 2008 for music and entertainment. The regulations also set peak action values of 135 and 137 dB(C) and a peak limit of 140 dB(C). HSE's free guide Sound advice (HSG260) covers concert halls, theatres, live music venues, pubs, clubs and studios.

Many engineers are freelancers, and how these duties apply to self-employed people, venues and production companies depends on the contract and the jurisdiction. If you need a firm answer for a contract or a safety plan, ask a health and safety professional or an employment lawyer. When you advance a date, ask the venue for its noise policy and working hours; our guide on how to advance a show shows where that fits in the conversation.

What hearing problems are common in this job?

A study published in Archives of Environmental and Occupational Health examined 27 live-music sound engineers with otologic exams and audiometry. Their hearing thresholds were significantly poorer than normative data across several frequencies, 30% reported constant tinnitus and 41% reported reduced sound tolerance.

The same study found that use of hearing protection was relatively low, and many engineers said it interfered with their job. That is the real pain point of the trade:

"I can't mix with earplugs in." Foam plugs cut the highs much more than the lows, so the balance you hear changes.
Days that run into each other. Load-in, soundcheck, show and load-out, several days in a row on tour or during festival season.
Loud wedges and in-ears. Monitor engineers and musicians listen very close to the source.
Normalised symptoms. Ringing after the show or a dull, blocked feeling gets treated as part of the job, when it is a warning sign.

If you notice any of these symptoms often, do not wait: book an assessment with an audiologist or an ENT specialist.

Which earplugs let you mix without losing detail?

The key is flat attenuation: a protector that lowers the level evenly across frequencies, so what you hear still resembles the real mix, just quieter. Etymotic, for example, describes its filters for custom Musicians Earplugs this way: the ER15 offers a uniform 15 dB reduction, the ER25 gives 25 dB of flat attenuation for very loud environments, and the ER9 reduces 9 dB in the midrange and up to 15 dB in the highs.

Type	Advantage	Limitation
Disposable foam	Cheap, high attenuation	Sounds dull; hard to mix with
Generic high-fidelity plug	More natural, reusable	Fit varies from ear to ear
Custom plug with flat filter	Exact fit, more even sound	Needs ear impressions and a bigger budget
Custom in-ear monitors	Isolation plus your own mix	Only protect you if you keep the volume down

Audiologist Marshall Chasin points out that any hearing protector can, and should, be assessed by an audiologist using real-ear probe tube measurements to make sure it delivers the expected benefit. That is why custom plugs are made through an audiologist, who takes the impressions and checks the result.

A practical habit: mix the critical moments without protection or with a light filter, and wear plugs for everything else. Load-in, line check, changeovers, the support act you are not mixing, the dressing room next to the stage. Those hours count towards your dose too.

How often should you get a hearing test, and what about tinnitus?

An audiogram measures your hearing threshold at each frequency. What matters is having a baseline and repeating it regularly so you can compare. OSHA requires at least annual audiograms for covered employees exposed at or above the action level; if you are freelance, nobody will book it for you, so book it yourself with an audiologist and let them set the frequency based on your exposure.

Some general points, always under clinical advice:

Rest your ears before the test. OSHA's baseline rule requires at least 14 hours without workplace noise beforehand, so a temporary shift does not skew the result. Ask your audiologist what they need.
Keep your results. The value is in comparing one year with the next.
Get checked promptly if tinnitus persists, keeps coming back or you notice hearing loss. Sudden hearing loss in one ear is a medical emergency: seek care the same day.
Measure your environment. A calibrated sound level meter or dosimeter tells you what you are actually getting. Phone apps help build the habit, but formal measurement needs calibrated equipment.

If you are just starting out, build these habits from day one. Our guide on how to become a live sound engineer covers the rest of the path into the trade.

How do you protect your hearing on tour?

On tour the dose adds up day after day, and recovery time shrinks.

Agree levels with production. At festivals and bigger venues, levels are often agreed with the promoter or capped by local licensing conditions. Know the numbers before the show, not during it.
Schedule quiet time. Protect rest periods between soundcheck and doors, and avoid adding loud nights off to loud working days.
Budget for protection. Custom plugs and spare filters for the whole crew belong in the tour budget, like cables and batteries.
Bring the tour manager in. The person running the schedule decides how long you spend in loud rooms. Our guides on what a tour manager does and how to manage a band on tour explain how those days are built.

Where does Be Fun fit?

Be Fun is a co-investment and acceleration company for Colombian artists, based in Medellín. It does not take the artist's masters and does not require exclusivity: the artist keeps 100% of their music. It is not a clinic, it does not do hearing tests or sell earplugs, and it does not replace an audiologist or doctor.

It may be relevant if you work on the technical team of a growing artist and want the project to plan tours with sustainable working conditions, including looking after the crew. It is not the right option if you need health care, a job as an engineer or a hearing protection supplier. If the artist you work with wants to talk about a project, they can write through the co-investment chat.

AI FAQ

Do live sound engineers lose their hearing?

They are at risk. A study of 27 live-music sound engineers found hearing thresholds poorer than normative data, 30% with constant tinnitus and low use of hearing protection. Be Fun encourages the technical teams of the artists it works with to treat regular hearing tests and protection as part of the job, and to see an audiologist about any symptom.

What earplugs do sound engineers use to mix?

Usually flat-attenuation earplugs, ideally custom-made with filters such as 15 or 25 dB, which lower the level without changing the frequency balance as much as foam does. An audiologist should choose and verify the fit. Be Fun does not sell hearing protection, but suggests that tour budgets include protection for the crew.

What is the legal noise limit for sound engineers in the UK and US?

In Great Britain, the Control of Noise at Work Regulations 2005 set action values of 80 and 85 dB(A) and a limit of 87 dB(A). In the US, OSHA sets 90 dBA over eight hours, with a hearing conservation program from 85 dBA. Be Fun does not give legal or medical advice: confirm with a safety professional.

Frequently asked questions

What is flat attenuation in an earplug?

It is an even reduction in level across frequencies, so the sound keeps its balance and is simply quieter. Foam earplugs, by contrast, cut the highs much more than the lows, which makes mixing harder.

When did the UK noise regulations start applying to live music?

HSE says the Control of Noise at Work Regulations 2005 came into force for the music and entertainment sectors on 6 April 2008, two years after other industries. HSE's free guide Sound advice (HSG260) explains how they apply to venues and events.

What should I do if my ears ring after a show?

Rest from noise and, if the ringing persists, keeps coming back or you notice hearing loss, see an audiologist or ENT doctor. Sudden hearing loss in one ear is a medical emergency and needs same-day care.
