Most people can hear their heartbeats when they go into a very quiet room. Because the ear is so sensitive, it is able to pick up the pulse from our bodies. I hear mine too, sometimes! When healthy people are over-tired or over-heated, they also may hear a pulse beat in the ear. The carotid arteries, which are big blood vessels carrying blood from your heart to your brain, run on either side of your neck, close to your ears. So it is louder with exercise or exertion because your pulse pumps harder during exercise or activity.
If your nose is very congested, pressure can build up in your Eustachian tubes, which connect the back of the nose and throat to the ears. Without our ear being able to hear normal sounds of the world around us, it picks up on the sound of our own pulse. Taking a decongestant or blowing your nose often might decrease the intensity of the pulse.
