Possible responses:→ No / don't know

The carotid artery passes about 1/8th inch behind the ear drum. Consequently, one will often hear flow through the artery and this generally doesn't mean anything. However, an ultrasound will rule out possible narrowing (stenosis) of the artery since this is something that should be followed/fixed depending on the severity. A "swishing" sound may occur as blood flows past a blockage in a carotid artery.
Some patients may notice a "swishing" noise in either ear with each heartbeat. This sound may occur as blood flows past a blockage in a carotid artery.
Although it is not unusual for some people to hear their pulse in their ear(s), if onset is recent then it might be wise to see a doctor and make sure it is not due to an elevation in blood pressure.
People with pulsatile tinnitus typically hear a regular sound that occurs in time with their heartbeat.
