The definition of tinnitus is perceiving a sound in the ears or head when there is not an actual external source for this sound. Put simply, tinnitus is the perception of a non-existing sound. A person hears the ringing in his or her ears or head, but no one else does.
Pulsatile tinnitus is also ringing in the ear, but can be described as a swishing sound that usually beats with the heart. The sound may be aggravated with exercise, as the heart rate increases, for example. Sometimes the sound is so intense that it may be disruptive to a person's sleep or daily life. One of the causes may be due to the sound of blood flowing through vessels transmitted near the ear. Often, diagnosis of the cause of pulsatile tinnitus involves the imaging of the vascular system of the head and neck.
