oh wrt to hearing your own heartbeat, there should be a filter in the brain (or hearing system?) that should take out just that. Quite possibly this is only an attenuation , and when the noise floor is low we can still hear it.
A doctor that dealt with these told me that there's even a condition where this filter doesn't work, unfortunately . It's apparently maddening to constantly hear the heartbeat at full force.
Happens to me when I have insomnia.
It's terrible.
It could be worse, though. Our brain also has a filter to put out the presence of our nose from our vision. Imagine if we were constantly distracted by our own nose.
