Yes: Tinnitus is perception of noises in one's ear/ears. It can be a pulse like sensation, it can be a humming, buzzing, or a ringing. It is very, very common.

You have tinnitus: What you are describing is called "pulsatile" tinnitus. It is fairly common and usually due to a blood vessel near your inner ear or hearing nerve. You should see an ENT doctor for an evaluation.

Ringing in the ear: It could be, i would see your physician for some tests. It can be very annoying.
