Not all the time but occasionally in quiet moments I can hear a pulsing in my ear that matches my heartbeat. Been able to hear it since I was a child. Mostly it’s localised to one ear and generally it will quieten/ stop after a short while.

      Can confirm. Like bubbly water being squeezed through a thin tube. As a kid, I thought it was air bubbles farting their way through a narrow blood vessel.
