what causes sensitivity to noise
Introduction. Hyperacusis is an extreme aversion and hypersensitivity to sounds that are generally not an issue to others. Electrical and machine noises, as well as sudden high-pitched noises, are usually hard to tolerate for people with hyperacusis (examples are listed in the box on this page). However, any sound can potentially trigger a reaction in someone with hyperacusis â even the sound of their own voice.
