Dr. Abd Elbary adds that localized increases in blood flow, often caused by tumors, can also trigger these sensations. “Most tumors are benign, but it’s still important to get checked,” he warns.

So what causes that heartbeat sound? Most often, it’s a change in blood flow or heightened awareness of tiny vessels in the ear. Certain factors can make PT more noticeable, including exercise, pregnancy, an overactive thyroid, or anemia.

While many cases of PT resolve on their own, persistent or worsening symptoms deserve a professional evaluation. A doctor can rule out serious causes and provide guidance to manage the condition.

If you or someone you know is experiencing these pulsating ear sounds, don’t ignore them. Get checked, stay informed, and protect your health.
