Why Do Some People Hate The Sound Of Chewing And How Common Is It

For many, sharing a meal is a social pleasure—conversation, laughter, and good food. But for others, that same experience can be unbearable. The rhythmic crunch of chips, the wet smack of chewing, or even the quiet click of someone sipping from a straw can trigger intense irritation, anxiety, or anger. This isn’t just about being “annoyed.” It’s a real and often misunderstood condition affecting millions worldwide. So why do some people hate the sound of chewing—and just how common is this reaction?

The answer lies in a neurological phenomenon known as misophonia, literally meaning \"hatred of sound.\" While not yet fully understood, research has begun to uncover the brain mechanisms behind this sensitivity. What was once dismissed as mere annoyance is now recognized as a legitimate sensory processing issue with measurable emotional and physiological responses.

Understanding Misophonia: More Than Just Dislike

Misophonia goes beyond general noise sensitivity. It's characterized by strong emotional reactions—such as rage, disgust, or panic—to specific sounds, most commonly those produced by other people. These are typically repetitive, pattern-based noises like chewing, breathing, pen clicking, or foot tapping. Unlike hyperacusis (a heightened sensitivity to volume) or phonophobia (fear of certain sounds), misophonia is triggered by the meaning or context of a sound, not its loudness.

Neuroimaging studies suggest that individuals with misophonia show abnormal connectivity between the auditory cortex and the anterior insular cortex, a region involved in emotion regulation and self-awareness. When a trigger sound occurs, this network activates intensely, leading to a fight-or-flight response—even if the sound itself is objectively quiet.

“Misophonia isn’t about being oversensitive to noise; it’s about the brain assigning emotional significance to certain sounds that others filter out automatically.” — Dr. Jennifer Jo Brout, Clinical Psychologist and Misophonia Researcher

This explains why someone might remain calm during a loud concert but feel enraged by their coworker quietly eating an apple at their desk. The brain interprets the chewing not as background noise, but as a personal threat or violation.

How Common Is Misophonia?

Estimates vary, but research suggests that misophonia affects approximately 5% to 20% of the population to some degree. A 2013 study published in *PLOS ONE* found that around 20% of participants reported experiencing symptoms consistent with misophonia, though only a subset met full criteria for clinical severity.

It often emerges in late childhood or early adolescence, typically between ages 9 and 13. Many sufferers report that their first triggers were family members’ eating habits—parents chewing with their mouths open, siblings slurping soup, or a sibling smacking gum. Because these sounds occur in intimate settings, the emotional impact can be profound and long-lasting.

Despite its prevalence, misophonia remains underdiagnosed. Many people suffer in silence, believing they’re simply “too sensitive” or overreacting. Only recently has it gained attention in mainstream psychology and neuroscience, leading to increased awareness and validation for those affected.

Common Trigger Sounds

• Chewing, crunching, or lip-smacking
• Swallowing or gulping drinks
• Nasal sounds: sniffing, whistling, heavy breathing
• Repetitive mouth noises: gum popping, tongue clicking
• Typing, pen clicking, or foot tapping
• Whispering or soft speaking

Tip: If you suspect you have misophonia, keep a symptom journal. Note when and where reactions occur, what sounds triggered them, and how intense the response was. This can help identify patterns and support discussions with healthcare providers.

The Emotional and Social Impact

Living with misophonia can be isolating. Meals become minefields. Family dinners, office lunches, or even watching TV shows with exaggerated eating sounds can provoke distress. Some individuals avoid restaurants, shared workspaces, or public transportation altogether. Others endure these situations while internally coping with elevated heart rate, sweating, or intrusive thoughts.

Social relationships often suffer. Partners may feel accused or defensive when asked to eat quietly. Parents may misunderstand their child’s outbursts during dinner. In severe cases, people withdraw from friends and family, fearing judgment or conflict.

“I used to dread holiday meals. My dad’s chewing drove me into a silent rage. I’d excuse myself early, claiming I wasn’t feeling well. It wasn’t until years later I realized it wasn’t me being ‘rude’—it was my brain reacting abnormally.” — Sarah L., age 34

This emotional toll underscores the importance of recognizing misophonia as more than a quirk. It’s a condition that disrupts daily functioning and quality of life, much like other sensory processing disorders.

Do’s and Don’ts for Managing Misophonia

Do	Don't
Use noise-canceling headphones or earplugs in high-risk environments	Confront someone aggressively during a trigger episode
Communicate your needs calmly and clearly to close contacts	Assume everyone will understand without explanation
Practice mindfulness or grounding techniques to regulate emotional response	Isolate yourself completely—maintain social connections when possible
Seek professional support from audiologists or therapists familiar with misophonia	Blame yourself for your reactions
Create low-sound zones at home for recovery after exposure	Rely solely on avoidance as a long-term strategy

Strategies for Coping and Relief

While there is no cure for misophonia, several evidence-informed approaches can reduce symptom severity and improve daily functioning.

1. Sound Management

Controlling auditory input is often the first line of defense. Noise-canceling headphones, white noise machines, or ambient background music can mask trigger sounds. Apps designed for misophonia offer customizable masking sounds tailored to common triggers like chewing or typing.

2. Cognitive Behavioral Therapy (CBT)

CBT helps individuals reframe their emotional response to trigger sounds. By identifying distorted thought patterns—such as “They’re doing this on purpose”—and replacing them with balanced perspectives, patients can reduce the intensity of their reactions over time.

3. Tinnitus Retraining Therapy (TRT) Adaptations

Although originally developed for tinnitus, TRT principles are being adapted for misophonia. This involves combining sound therapy with counseling to habituate the brain to trigger sounds, reducing their emotional salience.

4. Mindfulness and Relaxation Techniques

Practices such as diaphragmatic breathing, progressive muscle relaxation, and meditation can help regulate the autonomic nervous system. When a trigger occurs, these tools can prevent escalation into full-blown distress.

5. Environmental Modifications

Simple changes can make a big difference. Eating at different times than others, choosing quieter seating in restaurants, or using visual cues (like a hand signal) to request reduced noise can empower individuals without escalating tension.

Tip: Try listening to binaural beats or nature sounds through one earbud while leaving the other free to hear essential environmental cues—this provides partial masking without complete isolation.

Real-Life Example: Navigating Work Life with Misophonia

James, a 28-year-old software developer, struggled silently with misophonia for years. His breaking point came during a team lunch when a colleague loudly chewed celery sticks. James felt his chest tighten, his face flush, and an overwhelming urge to snap. He excused himself and spent the next hour in a bathroom stall trying to calm down.

After researching his symptoms, he realized he wasn’t alone. He scheduled a consultation with an audiologist who specialized in sound sensitivities. With guidance, James implemented several strategies: wearing discreet earbuds with low-volume pink noise during group meals, discussing his needs with his manager, and using a private room for focused work.

He also joined an online support group, which helped him feel less isolated. Over six months, his reactions diminished in frequency and intensity. “I still notice the sounds,” he says, “but now I have tools. I don’t feel like a ticking time bomb at every meal.”

Frequently Asked Questions

Is misophonia a mental illness?

No, misophonia is not classified as a mental illness in the DSM-5, though it often co-occurs with anxiety, OCD, or depression. It is increasingly viewed as a neurophysiological disorder involving the brain’s emotional processing networks. Proper diagnosis should come from a trained audiologist or mental health professional familiar with auditory sensitivities.

Can misophonia develop later in life?

While most cases begin in childhood or adolescence, some people report developing symptoms in adulthood, often following periods of stress, trauma, or hearing changes. However, retrospective analysis often reveals milder, previously unnoticed sensitivities earlier in life.

Are there medications for misophonia?

There are no FDA-approved medications specifically for misophonia. However, some individuals benefit from medications that target associated conditions, such as SSRIs for anxiety or beta-blockers to manage physical symptoms of stress. Treatment should be personalized and monitored by a healthcare provider.

Steps to Take If You Think You Have Misophonia

1. Track your reactions: Keep a log of triggering sounds, contexts, and emotional/physical responses.
2. Rule out other conditions: Consult an audiologist to exclude hearing disorders like hyperacusis or tinnitus.
3. Educate yourself: Read peer-reviewed articles or books from reputable sources on misophonia.
4. Reach out to specialists: Seek professionals experienced in auditory processing issues or sensory integration.
5. Build a support system: Talk to trusted friends or join online communities (e.g., Misophonia Association).
6. Implement coping strategies: Start with one or two manageable techniques, like using background noise or practicing mindfulness.
7. Advocate for accommodations: At work or school, request reasonable adjustments, such as flexible seating or remote options for meetings.
