No, it's not typically normal to hear your heartbeat in silence unless your heart rate is significantly elevated (e.g., after strenuous exercise). However, some individuals experience a condition called pulsatile tinnitus where they perceive a sound synchronized with their heartbeat, even at rest.
Understanding Pulsatile Tinnitus
Pulsatile tinnitus is a condition where you hear a rhythmic sound, often described as a whooshing, throbbing, or humming, that seems to beat in time with your pulse. This differs from the normal occasional awareness of a strong heartbeat. While a rapid heartbeat might be heard after exertion, pulsatile tinnitus presents as a persistent sound, even during rest.

Cause: The exact cause isn't always clear, but it often involves increased blood flow near the inner ear or changes in blood vessels.
-
Symptom: The primary symptom is the constant perception of a sound synchronized with the heartbeat. As the reference states, "When their heart rate increases, the beat or sound will become faster; when it decreases, the beat or sound will slow." This key characteristic distinguishes it from other types of tinnitus.
-
Contrast with Normal Heart Sounds: It's important to differentiate this condition from the normal, occasional awareness of a strong heartbeat following physical activity. Pulsatile tinnitus is persistent and occurs even in the absence of exertion.

Seeking Medical Attention: If you frequently hear a sound in time with your heartbeat, especially at rest, it's crucial to consult a doctor. They can determine the underlying cause and recommend appropriate treatment.
