Tinnitus is the medical term for hearing noises in your ears when there is no outside source of the sounds. Tinnitus is often called ringing in the ears, but it may also sound like blowing, roaring, buzzing, hissing, humming, whistling, or sizzling. The noises you hear can be soft or loud. You may even think you are hearing air escaping, water running, the inside of a seashell, or musical notes.
Unfortunately, music can also cause some serious harm in the form of tinnitus or other permanent hearing loss/damage. Tinnitus can result from listening to music at high volumes or amplitudes. Tinnitus is a buzzing in the ears that ranges from slight to severe. Tinnitus is a highly subjective condition; some patients claim to perceive sounds of animals or even popular songs.
