Hyperacusis After Trauma: Clinical Guidance

by Dr. Jennifer Gans 

Overview

- Hyperacusis = decreased tolerance to everyday sounds, often painful or overwhelming.
- Common in soldiers after blast injuries, PTSD, trauma, and prolonged noise exposure.
- Co-occurs with anxiety
- Often co-occurs with tinnitus.

The Facts:

- Symptoms are due to central auditory gain and fear conditioning, not structural ear damage.
- Trauma and hyperarousal amplify the perception of sound as threatening.
- Patients may describe ordinary sounds (dishes clinking, voices, doors closing) as painful or intolerable.

Common Misbeliefs

- “My ears are broken. Something is damaged.”
- “I’ll go deaf if I’m exposed to sound.”
- “I must protect my ears from all noise.”
→ These beliefs reinforce sound sensitivity and avoidance.

What Helps

- Accurate education: hyperacusis is benign and reversible.
- Sound enrichment (sound is safe and good!).
- Relaxation/mindfulness practices to lower hypervigilance.
- CBT or group therapy for anxiety and trauma.
- Address sleep issues.

What to Avoid

- Overuse of earplugs or over-protection (increases brain gain and sensitivity).
- Prednisone, unnecessary imaging, or invasive procedures (increase anxiety, no benefit).
- Reinforcing catastrophic beliefs.

Hyperacusis After Trauma: What You Need to Know
You Are Safe

- If ordinary sounds feel too loud or painful, it does not mean your ears are damaged.
- Your brain is temporarily “turning up the volume.”
- Hyperacusis is common after trauma and stress, and it is reversible.

Why It Feels Worse After Trauma

- Loud blasts/noise can make the brain over-sensitive.
- Stress and poor sleep put the brain on “high alert.”
- Fear memories connect sound with danger.

What Helps

- Learn the facts: hyperacusis is not ear damage.
- Expose yourself gradually to safe, gentle sounds (fan, nature, soft music).
- Avoid silence if possible – keep your ears busy and relaxed.
- Practice relaxation: breathing, mindfulness (see 5-Minute Breathing Exercise at MindfulTinnitusRelief.com).
- Stay active – don’t let sound sensitivity stop your life.

What to Avoid

- Don’t wear earplugs all the time (except in truly loud environments).
- Don’t Google horror stories about hyperacisis/tinnitus/hearing loss.
- Don’t believe the fear-based thought: “This means my ears are broken.”
- Avoid unnecessary medicines, scans, or scams.

👉 Bottom Line: Fear & Anxiety must be treated! With accurate education, sound exposure, and stress reduction, the brain resets its “volume control” and sound is no longer painful.
