Misophonia causes intense emotional and physiological reactions to specific sounds. This article explores misophonia symptoms, diagnosis, causes, and effective therapy options, including related conditions and practical coping strategies.
Misophonia is a complex neurological condition in which individuals experience extreme emotional and physical discomfort when exposed to certain everyday sounds, typically referred to as "trigger sounds." These are often subtle and repetitive noises, such as chewing, throat clearing, pen clicking, sniffing, or foot tapping. While these sounds are benign to most, a person with misophonia may experience sudden feelings of intense anger, anxiety, irritation, or distress when they occur.
Unlike general sound sensitivity or hearing disorders such as hearing loss or tinnitus, misophonia does not result from a problem within the ear itself. Instead, it involves an atypical connection between the auditory system and the limbic and autonomic nervous systems — the areas of the brain responsible for emotional regulation and physiological arousal. The condition is not related to the volume of sound but rather to the specific type of sound and its perceived intrusiveness. Misophonia can interfere significantly with daily life, affecting relationships, mental health, concentration, and participation in social activities. It is not classified as a hearing disorder in the traditional sense but shares some overlapping features with auditory processing issues.
Misophonia presents a unique blend of emotional, cognitive, and physical symptoms triggered by specific auditory cues. Emotional responses are often intense and may include sudden bursts of anger, irritability, anxiety, panic, or even emotional shutdown. These reactions tend to be automatic and disproportionate to the actual sound stimulus. Over time, individuals may begin to anticipate these reactions, leading to chronic stress and avoidance of potentially triggering environments.
Physically, symptoms may include an increased heart rate, rapid breathing, muscle tension, sweating, and a sensation of pressure in the ears or head — especially in enclosed or quiet environments where triggering sounds become more pronounced. Some individuals report secondary symptoms similar to those found in tinnitus or hyperacusis, such as auditory fatigue, ear discomfort, or temporary oversensitivity to surrounding noises. The severity of symptoms can vary significantly, ranging from mild irritation to severe emotional and physiological distress that may limit the individual’s ability to work, study, or engage socially.
While both misophonia and hyperacusis involve abnormal responses to sound, they differ in their root causes, symptoms, and emotional impact. Hyperacusis is a condition in which a person perceives ordinary environmental sounds as abnormally loud or even physically painful. It often stems from issues within the auditory system — such as damage to the cochlea or dysfunction in the auditory nerve pathways — and may follow acoustic trauma, inner ear infections, or noise-induced hearing loss.
Misophonia, in contrast, does not relate to sound intensity but rather the emotional significance attached to certain sound patterns. For example, someone with misophonia might feel deeply distressed when hearing another person chew or breathe heavily, regardless of how quiet the sound is. Meanwhile, a person with hyperacusis might react negatively to the volume of a vacuum cleaner or motorbike engine. Although both conditions can coexist, misophonia is distinguished by its strong emotional component and the personal interpretation of the sound as intrusive, disrespectful, or unbearable. Proper differentiation between the two is critical, as treatments and coping strategies differ significantly.
Diagnosing misophonia involves a multidisciplinary approach led by qualified doctors, including GPs, audiologists, ENT specialists, and clinical psychologists. While misophonia is not yet officially recognised in diagnostic manuals, many healthcare professionals are increasingly familiar with its symptoms and impact.
The process usually begins with a GP, who can refer the patient to relevant specialists for further evaluation. Audiological assessments such as pure-tone audiometry and Loudness Discomfort Level (LDL) testing help rule out hearing loss and distinguish misophonia from related conditions like hyperacusis or tinnitus.
Psychologists may use tools like the Misophonia Questionnaire (MQ), Amsterdam Misophonia Scale (A-MISO-S), or MisoQuest to measure symptom severity and emotional impact. In some cases, controlled sound exposure tests are conducted to observe reactions to trigger sounds in a safe, clinical setting.
Although there is no single definitive test, this combination of medical and psychological evaluations enables doctors to make a reliable diagnosis and recommend appropriate treatment strategies.
Conditions like misophonia deserve proper attention, not one-size-fits-all solutions.

What causes misophonia remains an area of ongoing research, but current evidence suggests that it stems from atypical interactions between the brain’s auditory system and the regions responsible for emotional and physiological responses — particularly the limbic system and the autonomic nervous system. These irregular neural connections may cause certain everyday sounds to be perceived as emotionally threatening or intolerable, rather than merely annoying.
Misophonia often does not occur in isolation. It is frequently associated with other neurological, sensory, or mental health conditions, which may either contribute to its development or intensify the severity of symptoms. Below, we outline the most commonly linked causes and co-occurring conditions that can influence how misophonia manifests and progresses.
Tinnitus, the internal perception of sound such as ringing, buzzing, or hissing in the absence of an external source, shares several functional and emotional features with misophonia. Individuals who live with tinnitus often report increased awareness of environmental sounds, particularly in quiet settings where intrusive auditory perceptions are more prominent. This constant focus on auditory input can heighten one’s sensitivity to external noises, potentially mirroring or aggravating misophonic reactions.
Both conditions involve atypical auditory processing and an overactive emotional response to sound. In tinnitus, the brain attempts to compensate for a lack of sensory input, whereas in misophonia, benign sounds are misinterpreted as emotionally threatening. When tinnitus and misophonia co-exist, individuals may struggle with layered sensitivities — managing both an internal noise and heightened reactivity to external triggers. The combination can significantly affect daily comfort and emotional wellbeing, making early identification and specialised auditory support critical.
A growing body of research supports a connection between Attention Deficit Hyperactivity Disorder (ADHD) and misophonia. ADHD is often characterised by impulsivity, difficulty sustaining attention, emotional dysregulation, and sensory sensitivities — all of which can contribute to misophonic responses. Many individuals with ADHD describe feeling overwhelmed by certain environmental stimuli, especially when their attention is already strained or when emotional regulation is challenged.
Auditory sensitivity in ADHD may stem from inefficient sensory filtering, meaning the brain struggles to prioritise relevant sounds and suppress unimportant noise. This heightened awareness of background sounds can lead to increased reactivity to specific auditory triggers, such as keyboard typing or foot tapping. The emotional response to these sounds — including frustration, anger, or panic — may be further amplified by ADHD-related difficulties in emotional control. This creates a reinforcing cycle that can make managing misophonia symptoms particularly challenging for individuals with ADHD.
The emotional and behavioural impact of misophonia in autistic individuals can be significant. Triggers may lead to physical discomfort, shutdowns, or meltdowns, especially in environments where sensory input cannot be easily controlled. In ASD, misophonia may be underpinned by neurological differences in sensory integration, making certain sounds feel overwhelming or even physically painful. Additionally, autistic individuals may find it more difficult to communicate or contextualise their distress, which can complicate diagnosis and support.
Mood disorders such as depression, generalised anxiety disorder (GAD), and bipolar disorder have been consistently linked to increased sensory sensitivity and misophonia. Individuals living with these conditions often experience amplified emotional responses, reduced stress tolerance, and heightened physiological arousal — all of which can intensify misophonic reactions. For example, a person experiencing chronic anxiety may find themselves disproportionately disturbed by minor repetitive sounds, leading to avoidance behaviour or emotional outbursts.
In bipolar disorder, misophonia symptoms may fluctuate depending on the phase of the mood cycle. During depressive episodes, sound triggers may contribute to irritability and emotional exhaustion, while in manic or hypomanic states, sensory overload can lead to agitation or loss of focus. Though misophonia can occur independently, the presence of mood instability can exacerbate its impact on daily functioning. Addressing underlying mental health conditions is therefore essential in the holistic treatment of misophonia.
Exposure to psychological trauma can leave lasting changes in the way the brain responds to perceived threats — including sounds. In individuals with a history of trauma, the brain may become hypervigilant, constantly scanning for sensory cues linked to danger. In this heightened state of alertness, otherwise harmless noises (like coughing, swallowing, or slurping) may become associated with distress, anger, or panic. This is particularly true when specific sounds were present during the traumatic event or resemble elements of it.
Misophonia that emerges in the context of trauma may involve learned emotional responses and involuntary physiological reactions, such as increased heart rate or muscle tension. These responses are often automatic and difficult to control, even when the individual recognises that the sound poses no real threat. Trauma-informed care and therapy — including cognitive behavioural interventions or EMDR — may be beneficial in addressing these conditioned reactions.
Hormonal fluctuations during menopause and perimenopause can have a profound impact on emotional regulation, sleep, and sensory perception. Some women report a noticeable increase in sound sensitivity or irritability during this stage of life, which may contribute to or worsen misophonia symptoms. While scientific studies on the relationship between menopause and misophonia are still limited, anecdotal reports suggest that hormonal shifts — particularly in oestrogen and progesterone levels — may alter the brain’s threshold for sensory tolerance.
This increased sensitivity can be especially challenging when combined with other common menopausal symptoms, such as anxiety, mood swings, or sleep disturbances. In some cases, women experiencing misophonia during menopause may also report new onset tinnitus or general auditory discomfort, further highlighting the link between hormonal health and sound reactivity.

Yes, misophonia can develop at any stage of life, although it most commonly emerges in late childhood or early adolescence. When symptoms first appear in adulthood, they may be triggered by significant stress, prolonged exposure to repetitive noises, emotional trauma, or even shifts in sensory perception associated with hearing conditions such as sudden hearing loss or worsening tinnitus.
Ageing itself does not cause misophonia, but age-related hearing changes like presbycusis — the gradual loss of hearing in older adults — may make certain sounds more noticeable or irritating, potentially altering auditory tolerance. In some cases, long-term coping patterns established earlier in life may begin to break down under new stressors, causing misophonic symptoms to become more pronounced. Although symptoms may intensify without appropriate support, there is no evidence that misophonia inevitably worsens with age, and many individuals learn to manage their triggers effectively with the right interventions.
