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.
Signs of hearing loss may also include lack of enjoyment from sounds such as a squeaking noisemaker, ringing bells or a rattle shaking; inability to imitate sounds by 6 months; doesn't begin to babble to himself or others; and does not respond to changes in voice tones.
