Tinnitus: Tinnitus is actually a very complex perception of some type of noise or sound in the ears or head. There are different types, subjective (only you hear) or objective (others can hear the noise too-rare). It can be pulsatile like a heart beat or non-pulsatile. There can be many causes and it really needs a full evaluation by an otolaryngologist.
