What is Noise sensitivity (hyperacusis)?

Hyperacusis is an increased sensitivity to everyday sounds, where noises that wouldn't normally bother most people, such as running water, chewing, or traffic, feel uncomfortably loud or even painful. It can occur alone or alongside tinnitus.

It can develop after exposure to loud noise, head injury, certain migraines, or conditions affecting the facial nerve, though sometimes no clear cause is found. It can range from mild irritation to a significant impact on daily life.
