The morning after a Hongdae gig in 2012, I woke up to a ringing in both ears that did not go away. It was not the usual post-club tinnitus that fades over a shower and a coffee. It stayed through breakfast, through lunch, through a long afternoon walk along the Han River, and through the quiet evening I spent trying to pretend it was not there. By Monday it had softened but not disappeared. My hearing had been slightly damaged by a long peak-time set played too close to a blown-out monitor in a room that had never been properly treated for acoustics. I was thirty-two years old, and I had just taken a small chip out of a sense I needed for my career. I have worn earplugs at every gig since.
This post is a serious one. I play in Seoul where the clubs are loud and the culture is forgiving about volume, and I have seen more hearing damage in working DJs than in any other group of friends I have. The damage is permanent, cumulative, and largely preventable. If you are a DJ in 2026 who has not taken hearing protection seriously yet, the case for doing so is overwhelming and the investment required is modest. The rest of this piece is what I wish somebody had told me, clearly, when I was twenty-two and new to the booth.
What Decibels Actually Do to Your Ears
Human hearing damage is a function of two variables, the sound level in decibels and the duration of exposure. The thresholds are well-documented. At eighty-five decibels, which is roughly a busy street, you can safely be exposed for eight hours. For every three decibels above that, the safe duration halves. At ninety-four decibels, typical of a club at moderate volume, the safe duration drops to about an hour. At one hundred and three decibels, which any peak-time club set exceeds, the safe duration drops to about fifteen minutes. A DJ playing a three-hour set in a room running at a hundred and eight decibels is absorbing doses of noise exposure in the hundreds of multiples of what their ears can handle without damage.
The National Institute for Occupational Safety and Health publishes the standard safe exposure thresholds, and reading through them as a working DJ is a sobering exercise. The damage in a single night of playing at peak-time volume can be, by those charts, equivalent to what a construction worker absorbs in a full eight-hour shift with power tools. That is the scale of the risk. The fact that most working DJs do not wear earplugs is a reflection of professional culture rather than a reflection of the physics. The physics says you should. The culture is wrong on this one, and the culture is slowly catching up.
The Two Kinds of Hearing Damage DJs Face
There are two distinct hearing problems a working DJ is at elevated risk for. The first is noise-induced hearing loss, which is a permanent reduction in your ability to hear specific frequency ranges. This most commonly shows up first as difficulty distinguishing voices in noisy rooms and a reduced sensitivity to high frequencies. Once you have it, it does not come back. You can protect the hearing you still have, but you cannot recover what you have already lost.
The second is tinnitus, which is a persistent ringing, buzzing, or whistling in the ears that has no external source. Tinnitus ranges from mild and intermittent to severe and constant, and in its worst forms it is actively debilitating. For DJs whose livelihood depends on hearing music clearly, tinnitus is a specific career-ending threat. I have several friends in the scene who cannot DJ anymore because their tinnitus has reached a level where they cannot tell the difference between a kick drum and internal noise. None of them thought it would happen to them. All of them wish they had started wearing earplugs earlier.
The Earplugs That Actually Work for DJs
Musicians’ earplugs are different from construction-site earplugs in one critical way. They reduce the volume evenly across frequency ranges rather than dampening the high end more than the bass. For a DJ, this is the difference between being able to mix properly through earplugs and not being able to. Generic foam earplugs will reduce the volume enough to protect your hearing, but they will also muffle the top end and make it impossible to hear the cues that actually matter for mixing. You cannot beatmatch through cheap foam earplugs. You can through musicians’ plugs.
The entry-level option that works well for most DJs is the Etymotic ER20 or the newer ER20XS, which costs around twenty US dollars and gives you roughly twenty decibels of flat attenuation. These are what I would recommend to any DJ who has never owned hearing protection. The step up is custom-moulded musicians’ plugs from a local audiologist, which cost between two hundred and five hundred dollars depending on the filters, fit your ear canal exactly, and are far more comfortable for long sets. I have had a pair of custom-moulded plugs from a Seoul audiologist since 2014 and they were the single best career investment I have ever made.
Monitor Volume, Booth Acoustics, and What a DJ Can Control
The thing every working DJ should learn, early, is how to ask for monitor volume to be lowered without losing the ability to mix. You do not need your monitors at peak-time levels to beatmatch. You need them loud enough that you can hear the transitions clearly, which for most rooms is five to ten decibels quieter than DJs tend to set them. A common mistake is to push monitor volume up to compete with main-room volume, which doubles the exposure you are taking.
Ask the sound engineer to help you find a monitor level that works. If the booth does not have a dedicated monitor control, talk to the club about it before your next booking there. A room that cares about its DJs will have a way for you to adjust your exposure. A room that refuses is a room you may want to think about whether to play again. The other thing you can control is where you stand. If the booth is near a main speaker, moving even a meter or two further away can cut your exposure significantly, because sound intensity drops with the square of distance. Small physical adjustments add up across a long career.
The Myths You Can Safely Ignore
There are several myths in the DJ scene about hearing protection that are simply wrong. The first is that earplugs will make it impossible to mix. Not true, at least not with musicians’ plugs. Every working DJ I know who has switched to proper plugs reports no meaningful drop in mix quality after a two-week adjustment period. The second myth is that hearing damage is something that happens to older DJs. It is cumulative over a career, but damage starts from the first night and builds from there. Twenty-two-year-old DJs playing loud rooms are already taking measurable damage whether they feel it or not.
The third myth is that the post-gig ringing is normal and not concerning. It is the direct audible signal that you have exceeded a safe exposure threshold. Any time you walk out of a club with ringing ears, your ears are telling you that damage has occurred. The ringing fading overnight is not recovery. It is habituation to the damage. If you have ringing ears after a gig regularly, you are in the process of developing tinnitus even if you do not yet have a chronic case. For general health advice on this, the World Health Organization publishes useful summaries.
What to Do if You Already Have Some Damage
If you already have mild tinnitus or some reduced hearing, the first and most important thing you can do is stop making it worse. Start wearing earplugs at every gig, immediately. Visit an audiologist for a baseline hearing test so you know where you are starting from. Commit to re-testing every two years to monitor whether the damage is stable or progressing. These steps are basic and they will extend how long you can keep working as a DJ by years, possibly decades.
For active tinnitus, a few practical things have helped the DJs I know who live with it. Sound-masking apps and devices can make the ringing less noticeable during quiet hours. Cognitive behavioural therapy has good evidence behind it for helping the brain adapt to the signal. Avoiding silence, paradoxically, is often useful because the ringing is most noticeable in the absence of other sound. I am not a medical professional, and any tinnitus serious enough to affect your daily life should be evaluated by a specialist. But the scene has enough working DJs living with manageable tinnitus that the path is well-trodden and the tools are accessible. For broader hearing-related workplace planning, a working DJ should also think about the economic side of the craft, because taking time off to protect hearing is sometimes a financial decision as well as a medical one.
FAQ
How loud is too loud for a DJ to play without hearing protection?
Anything above about ninety decibels sustained for more than an hour is already in the damage zone. Most club environments run between ninety-five and one hundred and ten decibels at the DJ booth. A working DJ should assume that every paid gig is loud enough to require hearing protection unless it is an explicitly quiet lounge or restaurant set.
Do foam earplugs from a drugstore work for DJing?
They protect your hearing but they will muffle the high end and make it difficult to mix cleanly. They are better than no protection, but not ideal. Musicians’ earplugs like the Etymotic ER20 series give you similar protection with a flat frequency response that preserves the mixing cues you need. The twenty dollars for a pair is one of the best small investments a DJ can make.
Are custom-moulded plugs worth the cost?
Yes, if you are a regularly-gigging DJ. The comfort over long sets is significantly better than any universal-fit plug, and the fit improves the acoustic performance. Expect to pay between two hundred and five hundred US dollars for a pair, and expect them to last five to seven years with normal use. Compared to the cost of lost earnings from hearing damage, the price is trivial.
What should I do if I get tinnitus that does not go away?
See an audiologist or ear-nose-throat specialist for a proper evaluation. Start wearing hearing protection at every gig if you are not already. Do not keep playing at the same volume level that caused the problem in the first place. The mild, early-stage tinnitus many DJs develop can stabilise if the underlying exposure is reduced, but it rarely stabilises on its own without intervention.
Is it too late to start protecting my hearing if I have already been DJing for ten years?
No. Every night of protection from this point forward reduces the cumulative damage going forward. DJs who start wearing plugs late in their careers still meaningfully extend the length of their working life compared to DJs who never start. The damage already done is permanent, but the trajectory from here is still yours to shape.
