Hyperacusis: increased sound sensitivity

Also known as: sounds too loud, noise intolerance, pain from sound, sensitive ears, auditory hypersensitivity, sound sensitivity.

Short answer: hyperacusis is an increased sensitivity to sound: everyday noises of normal intensity seem too loud, harsh or sometimes painful. It is frequently associated with tinnitus and involves how the brain processes sound. Management avoids both overexposure and over-protection, and usually relies on a gradual, controlled return to sound. No outcome can be guaranteed.

Hyperacusis: everyday sounds perceived as too loud or painful, often associated with tinnitus — Dr Grolman's ear-only practice near Béziers — Hyperacusis: ordinary sounds perceived as too loud or painful.

Many patients describe the same difficulty: "sounds seem too loud", "the noise of cutlery or dishes hurts", "I can't stand noisy places", "I have to wear earplugs all the time". Hyperacusis is an intolerance to sound that can have a major impact on daily life. It is different from simply disliking noise and deserves an assessment. This can be carried out in Colombiers – Béziers.

What is hyperacusis?

Hyperacusis is an increased sensitivity to sound: sounds of normal intensity, well tolerated by most people, are perceived as too loud, unpleasant or even painful. It does not mean the ear is "too good"; rather, the way the auditory system and the brain set the volume and tolerance to sound has changed. It can be compared to a gain setting that has become too sensitive.

What are the symptoms?

everyday sounds perceived as too loud: dishes, cutlery, traffic, voices, applause;
discomfort or pain triggered by certain sounds;
a need to avoid noisy places (restaurants, shops, transport);
frequent use of earplugs, sometimes constantly;
fatigue, tension or anxiety linked to anticipating noise;
often, associated tinnitus.

Hyperacusis and tinnitus: what is the link?

Hyperacusis and tinnitus very often coexist. Both involve the way the brain processes and "monitors" sound. When attention focuses on sounds and the system becomes hypervigilant, the perceived volume and the discomfort increase. This is why the two are often managed together, with a common logic: reducing excessive vigilance and re-habituating the ear to sound.

Not to be confused with…

Misophonia: a strong emotional reaction to specific sounds (chewing, breathing), without the sound being perceived as physically too loud.
Phonophobia: fear or anxious anticipation of certain sounds.
Recruitment: in some hearing losses, loud sounds quickly become uncomfortable; this is distinguished from hyperacusis on the audiogram.
Noise sensitivity in migraine: often transient and associated with other migraine features.

How is the assessment carried out?

The assessment is guided by the history and the examination. It may include:

a precise history (sounds involved, impact, how long);
an ENT examination and otoscopy;
an audiogram, sometimes with measurement of loudness discomfort levels;
a check for associated tinnitus;
an assessment of the impact on daily life.

The aim is to understand the mechanism, rule out another cause and adapt management.

What management?

Management of hyperacusis follows a key principle: neither overexposure nor over-protection. Wearing earplugs constantly, however tempting, can paradoxically worsen the sensitivity over time. Possible approaches, adapted to each case, include:

Explaining the mechanism, which reduces worry and excessive vigilance;
a gradual, controlled re-exposure to sound, to re-habituate the auditory system;
sound therapy (soft sounds, an enriched sound environment), sometimes offered;
protecting hearing only from genuinely intense noise (concerts, power tools), not in everyday life;
joint management of tinnitus and, if needed, of associated anxiety.

Improvement is often gradual. No outcome can be guaranteed, but an appropriate approach helps many patients regain better tolerance to sound.

When should you seek urgent care?

Seek prompt advice in case of: sudden hearing loss, severe ear pain, sudden onset of hyperacusis, recent pulsatile tinnitus, vertigo or facial paralysis. In an emergency, call 112.

Frequently asked questions

Does hyperacusis mean I hear "too well"?

No. It is not "superior" hearing: it is a reduced tolerance to sound. The auditory system and the brain set the perceived volume too sensitively, which makes normal sounds unpleasant or painful.

Should I wear earplugs all the time?

Usually not. Constant protection can reinforce the sensitivity over time. It is better to protect hearing only from genuinely intense noise, and otherwise re-habituate the ear to sound gradually.

Are hyperacusis and tinnitus linked?

Yes, very often. Both involve how the brain processes and monitors sound. They are frequently managed together, with a common logic of re-habituation and reduced hypervigilance.

Can hyperacusis improve?

Many patients improve with explanation, gradual re-exposure to sound and, if needed, sound therapy. The course varies from person to person and no outcome can be guaranteed.

What is the difference from misophonia?

In misophonia, specific sounds (chewing, breathing) trigger a strong emotional reaction without being perceived as physically too loud. Hyperacusis corresponds to sounds genuinely perceived as too intense or painful.
