When Sounds Become an Assault. From the movie "Tuner" to the Reality of Hyperacusis
This article contains spoilers about the movie “Tuner”.
If you have been following recent cinema news, you might have heard about Tuner (2026), the thriller directed by Daniel Roher. The film follows Niki (played by Leo Woodall), a promising virtuoso pianist whose career prospects collapse after developing severe hyperacusis. To survive the noise of the world, he wears constant hearing protection and retrains as a piano tuner, only to discover that his ultra-sensitive hearing lets him detect the micro-clicks of safes, making him an elite safecracker in the criminal underworld.
As someone living with this condition, seeing hyperacusis projected onto the big screen is a strange experience. On one hand, the film brilliantly uses sound design to make the audience feel the sheer violence of our everyday acoustic environment. On the other hand, it takes immense poetic license. In the real world, hyperacusis is not a cinematic superpower: it is an exhausting neurological overload.
In 2019, concurrently with my autism diagnosis, a medical consultation with an ENT doctor (Ear-Nose-Throat, or otolaryngologist) finally put precise words to what I experience. This article is an opportunity to lift the veil on this misunderstood hearing condition, explain its different faces, and share how it intertwines with autistic auditory processing.
What Is Hyperacusis? The 4 Components
Hyperacusis is often wrongly defined as a simple hypersensitivity to sound or "allergy to loud noises" (as Niki quickly defines it to Ruthie in the movie). Auditory research distinguishes between four components of sound intolerance:
Loudness: Everyday sounds (clattering dishes, a car engine) are perceived as if they are being played at an excessively loud, deafening volume.
Pain: Sound does not necessarily feel "loud," but it can trigger immediate, sharp, or burning pain inside the ear, even at incredibly low decibel levels (like the beep of a microwave).
Fear (also referred to as phonophobia): An anxious or protective anticipatory reaction to sound. When the brain associates noise with physical pain or aggression, it enters a fight-or-flight panic state before the sound even occurs.
Aversion (also known as misophonia): A disproportionate aversion, often fueled by intense irritation or anger, triggered by very specific organic noises (chewing, pen clicking, breathing), completely independent of their volume.
Which Type Does Niki Have in “Tuner”?
In the film, Niki suffers from extreme loudness hyperacusis. However, it is not quite clear to me what caused his hyperacusis. The scenario states that he was a prodigious pianist but stopped playing because of hyperacusis. At some point, Niki explains to Ruthie that when he was a child, he had to spend "two years in a dark room" for sound exposure therapy to be able to just be out there in the world again.
In any case, the film flirts heavily with the myth of "sensory compensation" by turning his injury into a gift. In reality, stepping next to a safe being drilled open (as depicted in the movie) would trigger immediate, agonising physical pain for the vast majority of hyperacusis patients.
When the Ear's "Volume Brake" Slips
In my case, the audiometry assessment is clear: I suffer from objective phonophobic hyperacusis triggering both pain and aversion responses. This is not a psychological quirk; it is a measurable mechanical and neurological dysfunction located at the heart of my Medial Olivocochlear (MOC) efferent system (MOCES) — efferent means away from center, meaning: brain-to-ear.
To understand this, imagine that the inner ear possesses its own automatic volume knob. When the world gets too loud, the brain sends a descending signal down the MOCES. This signal triggers the release of a neurotransmitter (acetylcholine) that stiffens the outer hair cells of the cochlea, acting as a physical brake to damp down sound vibrations before they ever reach the brain.
In my case, this automatic brake is broken, with a very strong predominance on my left side.
Because my MOCES is underactive, my cochlea mechanically amplifies everyday noises unchecked, treating a normal sound as if it were a whisper that needs boosting. In response, my ear has locked itself into a defensive grip: the ENT doctor noted that my stapedial reflexes (the stapes is the tiny middle ear muscle that contracts to block out blunt noise) are "very brisk." This measurement indicates my auditory system is stuck on high alert, which generates this profound phonophobia (fear hyperacusis).
How the Ear’s Internal Amplifier Works
To understand exactly what happens inside my ears, we need to take a microscopic journey inside the cochlea: the snail-shaped organ responsible for our hearing. This is where part of the issue lies, and it involves two very specific types of specialised cells.
Inner Hair Cells (The Microphones)
These are the official sensors of hearing. There are about 3,500 of them, and they function much like the keys of a mechanical piano. When a sound vibration arrives, these cells convert the physical movement (sound travelling as a wave through molecules of air) into an electrical signal (the language of our neurons). The inner hair cells (IHC) send this electrical signal to the brain via the auditory nerve.
In my case, the ENT doctor confirmed that my hearing is completely normal, meaning that my biological microphones work perfectly, and my inner hair cells are entirely intact.
Outer Hair Cells (The Amplifiers)
This is where the story takes a turn. We have about 12,000 of these cells. Their job is not to send sound to the brain, but to receive information back from the brain; some sort of feedback orders from the brain after the sound received and transmitted by the inner cells to the brain has been "assessed" by the brain. The outer hair cells (OHC) physically modify the mechanics of the inner ear:
When a sound is very faint (a whisper, the rustling of leaves), these cells elongate and contract like tiny biological pistons to boost and amplify the physical vibration. They are the reason human hearing is so incredibly sharp.
When a sound is loud, they are supposed to stiffen up, acting as shock absorbers to protect the inner ear.
In short, the OHC are the volume button of our hearing. Turning up the volume when sounds are very faint, and turning down the volume when sounds are very loud.
An Amplifier That Never Shuts Off
Normally, this amplifier is controlled by the brain via a specialised biological data cable called the Medial Olivocochlear Bundle (MOCB). This is our communication and feedback system between our ears and our brain. This MOCB is a two-way street: from ear-to-brain (afferent system) and from brain-to-ear (efferent system). The inner cells (the microphones) speak to the brain via the MOC afferent system. And the brain speaks back to the outer cells via the efferent system.
The MOC efferent system (MOCES) is basically the brain's volume knob. It acts as a mechanical governor to turn down the ear's internal volume. When the surrounding environment gets noisy, the MOCES injects a chemical neurotransmitter (acetylcholine) to tell the outer hair cells: “Stop, the volume is high enough, stop amplifying!”
In my case, and most severely on my left side, this control cable has a power failure. Because my MOCES fails to deliver the command to cut the amplification, my outer hair cells keep pumping and over-amplifying noises that are already loud enough. A simple crinkling of paper or the sound of footsteps receives the heavy-duty boosting treatment meant only for whispers.
It is this raw, mechanical over-amplification that bombards my auditory nerve, triggers physical distress, and forces my middle ear to panic, activating those "very brisk" stapedial reflexes. This is what makes my hyperacusis objective: it is a structural failure, not a psychological overreaction.
Sound Storm: Intersection of MOCES Dysfunction and Autism
Hyperacusis alone is hard enough to live with, as shown in the movie “Tuner”. For me, the even more exhausting aspects of my hearing in my daily life is how this mechanical failure interacts with my autism. Autistic individuals frequently experience sensory hypersensitivities, but in my case, two completely separate filtering breakdowns collide to create acute sensory overload.
The Collapse of Upstream and Downstream Filters
The autistic brain naturally struggles with attentional selectivity. It finds it difficult to prioritise information: the buzz of fluorescent lights, a distant conversation, and the hum of a computer fan are all processed with equal importance.
Normally, the MOCES assists the brain by physically dampening continuous background noise (allowing you to isolate a single voice in a busy restaurant; this is called the Cocktail Party Effect). The MOCES attenuates background noise and protects the ear from overstimulation. Because my MOCES fails to perform this mechanical filtering at the baseline, and my autistic brain cannot sort through the signals at the arrival point, I receive everything, all the time, at maximum volume. It's the auditory equivalent of standing on a white sand beach at noon at the Equator under a cloudless sky, eyes wide open with maximally dilated pupils, and no sunglasses. It's like if my ear had pupils that are maximally dilated, at all times.
The Vicious Cycle of Sensory Anxiety
Autism often involves a hyper-reactive amygdala (the brain's threat-detection center). When a sound bypasses my almost-absent physical defenses due to the MOCES failure, my nervous system desynchronises instantly. Stress spikes, and my heart rate accelerates. Crucially, stress further inhibits the MOC bundle's ability to function. The more I dread a sound, the more my body tenses up, the more hyper-reactive my stapedial reflexes become, and the worse the hyperacusis gets. And no "come on, that's not so loud, just relax" will help. It's not lack of willpower, it's a neuronal failure.
One last thing, and I'll close this section with this. Here is a couple of figures that speak for themselves. Hyperacusis is present in 2% of the general population and 69% of the (then called) Aspergers’, and 40% in the larger ASD (Autism Spectrum Disorder) population.
From Sound Storm to Sound Apocalypse: When Tinnitus Gets Invited to the Party
In the movie, Niki mentions "ringing in the ear" particularly after being exposed to sudden and loud sounds while having his ears unprotected. That's what is called tinnitus.
Tinnitus is the perception of sound in your ears or head when no external source is present. Often described as "ringing in the ears," it can also manifest as buzzing, humming, hissing, or whooshing sounds. It is not a disease, but rather a symptom that typically points to an underlying issue. Approximately 2% of the population is extremely bothered by tinnitus. It can be temporary (when you come back from a loud concert but is gone in the next day) or permanent.
I live with multiple permanent cases of tinnitus in each ear. One is a permanent and continuous high-pitched ringing; another one is also permanent and sounds like a police or ambulance sirene. I usually hear those most at night when going to bed or when I work and all is quiet. I have other instances of tinnitus which can last for a few seconds to a couple of minutes. Those appear suddenly and usually low-pitched and go with spinning (vertigo) and unsteadiness. I usually just sit and wait until it pass.
Generally, tinnitus results from a trauma where a sudden loud sound or overexposure to sound (concerts and festival, work and construction and other loud working environments) damages the hair cells. When those hair cells are damaged, they cease to play their part in the feedback ear-brain-ear system. The brain therefore compensates for what's not there anymore.
Think of it as an auditory version of phantom limbs syndrome. Someone with a missing arm might still feel pain in their hand. Similarly, if you can't hear highpitched sounds anymore because of hearing loss or damage, the brain is amplifying the signal that it is not receiving anymore. But what the brain is trying to amplify is not there (because the hair cells are broken and can't do their job). Tinnitus is actually amplified silence. So, the ear is not where tinnitus lives because the noise you hear (that relentles high-pitched ringing) is being generated by your brain.
My case of tinnitus is a bit more complex. My hyperacusis was detected very late in life, which means my brain has gone unprotected for decades. While this could have likely led to trauma, my audiometry shows intact hair cells and even a way-above-normal hearing across frequencies. My audiometry proves that you do not need dead or destroyed hair cells to experience severe tinnitus and hyperacusis.
This means that, in my case, tinnitus and hyperacusis are caused by a breakdown in the brain's internal volume-dampening feedback loop, rather than a loss of hearing sensitivity. Basically, my hair cells are healthy, but they are completely uninhibited by a MOCES that does not its regulating job. This lack of efferent inhibition allows spontaneous neural firing to run rampant in my brainstem. My auditory brain network mistakeds this uninhibited neural fireworks for external sound, generating the continuous high-pitched ringing and sirens I hear.
Hyperacusis and tinnitus are tightly linked: 40% of patients with tinnitus suffer from hyperacusis while 86% of patients with hyperacusis have concomitant tinnitus. Each increases the likelihood and severity of the other, in both general and autistic populations. Autistic people thus carry a particularly high burden of combined hyperacusis and tinnitus, often alongside broader neurodevelopmental and mental health challenges.
While I have my strategies to navigate tinnitus (brown noise at night and filtered-earplugs at day to avoid overprotection and worsening of the condition), tinnitus is just a nightmare to live with.
My message: whoever you are, whatever your neurotype or age: Take. Care. Of. Your. Hearing. Once damaged, hair cells die and cannot be mended and no hearing device will replace them.
My Daily Strategy
Fortunately, understanding the exact architecture of your own pain allows you to respond to it effectively. After my hyperacusis diagnosis, I went to an audiologist to get custom-fitted filter-holder with interchangeable 15dB and 35dB acoustic filters. They are designed to step in where my MOC system fails.
Here is my game plan for using them:
The 15dB Filter (my Translator): I wear this for daily life. It doesn't muffle the world; it simply scales down the physical intensity of sound evenly across frequencies. It artificially replaces the "slip" in my MOC brake, allowing my autistic brain to stay connected to the environment without saturating. Because my left side is the worst, I can even wear it just on the left ear to balance things out.
The 35dB Filter (my Shield): This is strictly reserved for sensory crises or high-risk environments (like supermarkets or public transit) to protect me from autistic overload and sensory meltdowns.
Niki uses his condition to crack open safes in Tuner. My goal is much simpler, yet infinitely more vital: to use these new tools to do what my auditory brain fails at: regulate even just a bit my nervous system, and restore a sense of harmony to the chaotic soundtrack of daily life.
"I totally get it. I'm super sensitive, too."
Since I started speaking openly about my hearing condition, I very often encounter this response, which is usually well-meaning: "Oh yeah, I totally get it, I can’t stand noise either these days!" or "Don't worry, we're all a bit hypersensitive down the line." — and we're not so close to the infamous "But aren't we all a bit autistic?" or the all-time-winner "But you don't look autistic."
While I know these comments come from a place of wanting to relate, they completely miss the reality and lived experience of actual hyperacusis.
There is a fundamental difference between psychological discomfort and neurological dysfunction:
Being annoyed by construction noise, struggling to concentrate in an open-plan office, or having a headache after a loud concert is a normal human reaction. Your internal filters are working perfectly fine; your environment is just objectively oversaturated.
In my case, hyperacusis means that my body processes a mundane background noise (the crinkling of a plastic bag, footsteps on a wooden floor) with the exact same physical intensity as a car horn blasting one foot away from my face. This is not a matter of mood, patience, victimhood, or emotional sensitivity. It is a failure of my physical sensors (the MOC system), which send an erroneous pain signal to my brain.
Telling someone with objective hyperacusis that you are "also a bit sensitive" is like telling someone with a broken leg that you understand their pain because your muscles are sore after a jog. The intention is kind, but the scale of the physical reality is simply not the same.
And while we're on that: please stop telling dyslexic people that you can relate because you also sometimes juggle letters a bit; and telling ADHD individuals that you can relate to what they go through daily because you also sometimes get a bit distracted. In short, don't project normal human behavior on altered neurology — And some people still firmly believe that autistic individuals don't have emotions (*sigh*).
A Myth-Debunking Q&A
Here's a list of remarks (questions, comments, and myths) that I often hear.
The pseudo-medical one: "But if you wear those all the time, your ears will get used to the silence and become even more sensitive!"
Reality: That's true for standard foam earplugs (like Quies) that cut out all sound. It's not true for 15dB filters, which let sound through attenuated. That's why, in my case, regular earplugs are banned. The 15dB filters just lower the volume like sunglasses for light. It keeps my ears working without hitting the pain threshold.
The distrustful one: "That's strange — you can hear us when it suits you / when we speak quietly, but the microwave noise hurts you?"
Reality: My MOCES is deficient, which means my ear doesn't know how to handle sudden changes or metallic/high-pitched sounds, even quiet ones. On top of that, my autistic brain can focus on a voice but be assaulted by a mechanical noise. It's not just about overall volume; it's about the type of sound frequency. My inner ear can no longer dampen sharp or sudden noises. A soft voice is perfectly fine, but the clattering of dishes triggers direct physical pain.
The impatient one: "Come on, make an effort — it's just a little background noise, you're overthinking it!"
Reality: Diagnoses are established using tools stemming from the same technology that screens every newborn’s hearing at birth. My stapedius reflexes are hyper-reactive. It's not mood-related or psychological. It's an anatomic anomaly of the peripheral nervous system, a neurological dysfunction. My physical sensors are broken: my ear sends a high-stress pain signal to my brain for a simple background noise. I can't override a physical reflex with willpower — Can you override the blink reflex with willpower? No.
The excluding one: "Right, we'll leave you in peace and not invite you — we don't want to hurt you."
Reality: The 15dB filters are precisely there to allow me to take part. I become isolated when I don't have my tools, not when I'm wearing them. I have these filters precisely so I can stay with you and join the conversation without pain. Don't change a thing, talk to me normally — my filters do the work.
Is Hyperacusis Something Someone “Has”?
What counts as dysfunction? Who decides the norms of auditory tolerance against which my sensitivity becomes a condition? Although recognised as a highly debilitating auditory condition, the onus and labour of adaptation falls on the individual rendered disabled by a set of organisational decisions, such as the prioritisation of open-plan offices. Who decides the standards of room and landscape acoustics?
River K. Barad is a physicist and philosopher who proposes to question the pre-given boundary between the organism (the individual, the body) and the environment (the institution, culture, education, etc.). Therefore, according to Barad, hyperacusis is not something someone has. Instead, hyperacusis is a phenomenon emerging not between but among the nervous system, sound waves, the built environment, and the norms that determine which bodies are expected to function in which acoustic spaces.
Hyperacusis is not just biological. A Baradian framework invites us to resist the temptation to locate hyperacusis within the individual body and to circumscribe it to a dysregulation of the auditory cortex, in which the body is a mere receiver of sound waves. The hyperacusic body and the painful sounds are co-constituted within a fabric of reality partly made of normalised built environments and acoustic standards.
The open-plan office participates in making the hyperacusic body the issue, the deviation. In my previous job, I was “offered the opportunity” to move my desk from the open-plan floor on the 4th floor to a cold storage room with no window in the basement on the -2 floor. That body becomes a site requiring intervention, such as a closed office, but separating the hyperacusic individual from the rest of the team. What is framed as the privilege of accommodation turns into exclusion and feels like punishment for not being able to “cope with the open-plan floor like everyone else” (this was actually said to me by my team manager — I eventually had to quit that job).
Closing Matters: Back to the movie “Tuner”
What the film can get praised for
Hyperacusis is notoriously difficult to communicate to people who don't have it. Tuner partially finds a cinematic language for that. The film lurches from near-silence to sudden, painful loudness so that the audience flinches alongside Niki. Through that, the audience, briefly and partially, inhabits what it means to live inside a gain dial turned too high.
Director Daniel Roher has said that both he and Leo Woodall consulted with people who actually live with hyperacusis before filming, wanting to understand how socially and emotionally alienating the condition can be. That care shows in the movie. Niki is not defined by his condition as a quirk or superpower — at least not in the film's better moments. He wears noise-cancelling earphones continuously, a former piano virtuoso reduced to tuning instruments he can no longer play because the sound is too painful. The loss is quiet, accumulated, and specific. That rings true.
Niki describes (his) hyperacusis simply as "being allergic to loud noises." It's extremely reductive, but it's what you say to people when you can't face the longer explanation. And let's be honest, no one wants to have a lecture on auditory neuroscience at the movie.
Surprisingly, it is within the movie's perimeter, in the reviews one can read online, that the discourse starts to soften the reality of this hearing condition. For all of you movie critics out there: no, hyperacusis is not a gift.
What the film gets wrong, or at least convenient
The film's premise depends on hyperacusis functioning as a superpower: exceptional sensitivity that, if you can just survive it, grants you abilities others don't have. Niki's "superpower" is actually a chronic illness being weaponised. And the film doesn't fully sit with the violence of that framing. The narrative logic quietly suggests that the suffering is worth it because of what it enables — the safecracking, the money.
Also, Niki has perfect pitch, which has a certain aura about it, and nothing to do with hyperacusis. Perfect pitch is the rare ability to identify or recreate a given musical note without a reference tone. It has been documented that hyperacusis co-occurs more frequently with perfect pitch in the musician population. However, there is no direct clinical or genetic evidence that hyperacusis and perfect pitch inherently co-occur. Still, they frequently overlap due to a shared neurological mechanism: increased central auditory gain.
And then there is the ending. (Stop reading now if you want to avoid spoilers).
Uri ruptures Niki's eardrums in a beating. Waking in hospital, Niki discovers he is now almost completely deafened but no longer needs earplugs to tolerate noise. In the final scene, he sits at a piano and plays a virtuoso performance for the first time in years.
I understand what Roher is doing. There is something genuinely moving in the image: the musician returned to music, even at cost. And the film earns some of that emotion. We have been with Niki long enough to feel the weight of what was taken from him.
But I can't quite let that go.
The resolution trades one disability for another and frames the exchange as bittersweet liberation. Hyperacusis is removed not through treatment, accommodation, or adaptation but through traumatic damage to the very system that was both the problem and "the gift". The implicit logic is uncomfortable: the body that suffered too much had to be partially destroyed before it could function. The instrument needed to be broken to be playable.
For those of us who live with hyperacusis not as a plot device but as a permanent feature of our nervous systems, this is a strange kind of consolation to be offered. The film imagines a release valve that doesn't exist. Real hyperacusis doesn't resolve into deafness. It just continues.
What stays with me
Despite this, I think Tuner matters. It is imperfect in the way that most first representations of invisible conditions are imperfect, reaching for dramatic resolution where lived reality offers none. But it puts hyperacusis on screen with enough seriousness that people who have never heard of it will leave the cinema with some felt sense of what it costs.
That is not nothing. It is, in fact, rather a lot.
I just wish Niki had found a way back to the piano with his eardrums intact. Not because I need films to be optimistic, but because that is the harder and more interesting story. And the one that would have been true.
