4 months agoI can do this. If I’m in a really quiet area, I like to take in a deeper breath and then exhale as slowly as possible while doing it, which then allows me to hear my heartbeat. Super nifty.
I can also use my soft pallet to block airflow from my throat to my nose. Can you do that too?
The trick is that while you hold your ears ‘open’, you have your lungs try to not breath out but you don’t close your mouth. This lets the heart beating against your lungs be what pushes air in and out and then you hear the sounds of the air pulses as it moves past your eustachian tubes in your throat. Making sure your lungs are as full as possible is required so the lungs push against the heart.
