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.
Hearing is an important part of everyday life, yet most people donât realize when they are damaging their ears. Causes of hearing loss include infections, aging, and brain injury, but one of the most common is noise exposure. Noise-induced hearing loss (NIHL) can develop after one occurrence of extreme noise exposure or after listening to very loud sounds over time.
