What is musical hallucination? Musical hallucination (MH) is the experience of hearing music when none is being played. Hearing sound that no-one else can hear is quite common, but the experience is normally of a simple sound such as a buzzing, ringing, or sizzling: this is known as tinnitus. In a small number of people however, these experiences can be more complex and emotive, and music can be heard.
People of all ages can suffer from hearing loss or hearing disorders. Most types of hearing disorders are caused by overexposure to excessively loud noises, aging, and genetic predispositions to ear problems. Other types can result from wax buildup, a ruptured eardrum, or a severe ear infection such as otitis media.
