Understanding misophonia

Misophonia involves decreased tolerance to particular sounds or stimuli associated with them. The 2022 expert consensus definition describes strong emotional, physiological and behavioural responses that are not typical for most other people. The intensity of a reaction cannot be explained simply by how loud a sound is. [1]

What can be a trigger?

Triggers differ between individuals. Examples reported in the literature include chewing, breathing, repetitive tapping and other human-produced or environmental sounds. Visual cues associated with triggering sounds may also matter. A list of examples is not a diagnostic checklist: a person’s experience, context and impairment deserve individual assessment. [1,2]

What reactions can occur?

Responses can include anger, anxiety, disgust, distress, physiological arousal, an urgent wish to leave the situation, or efforts to avoid anticipated triggers. The 2022 consensus recognizes that reactions may affect attention, activities and relationships. Researchers have measured heightened bodily and brain responses to personally salient triggers in particular study samples, but no scan or single laboratory response establishes a diagnosis. [1–3]

How can everyday life be affected?

A person may find shared meals, classrooms, open-plan workplaces, transport or healthcare appointments difficult when trigger sounds are unpredictable or cannot be avoided. Severity and impact vary. Some people need minimal changes; others need more substantial adjustments. Ask about the individual’s actual barriers rather than assuming every person has the same triggers. [1,2]

What research has established—and what remains uncertain

Researchers have documented distinct responses to trigger sounds and worked toward a shared definition. However, the mechanisms underlying misophonia, its prevalence across populations, its course over time and the comparative effectiveness of interventions remain areas of investigation. The consensus document specifically cautions against treating proposed causes or prevalence estimates as settled facts. [1–3]

What helps people respond constructively?

Start by asking what situations are difficult, what changes the person wants, and which adjustments are feasible. Examples include discussing a quieter place, flexible seating, advance notice about noisy procedures or control over optional electronic sounds. These are examples of accommodations to consider, not research-validated treatments. For clinical concerns, seek individualized advice from a suitably qualified professional.

Language and reporting guidance

Describe misophonia as a condition being actively studied. Avoid claiming that it is merely annoyance, that everyone experiences the same triggers, that a particular brain finding diagnoses it, or that any single treatment cures it. A consensus definition is not equivalent to formal inclusion in every diagnostic classification system.
