I suspect it is a mutation. Inside it feels like I’m squeezing the ear canal. I can only do it for about 30 seconds at a time, so its one of the weaker muscles. I was born with it and only realised others cannot do similar late in life.
I’m curious how prevalent this is wider, I was wondering if people with better hearing have the same capability, like in this community.
I do it automatically whenever a loud noise, loud truck passing, alarm goes off, someone shouts, etc.
The noise reduction is exactly the same as fingers in the ear, so can hear my own voice and just low bass from outside. If I put my little fingers in ear and turn my hearing off, I can feel in my finger the ear canal moving, so it’s likely being closed.
The side effect is my hearing is not damaged relative for my age. Also means my ear wax gets pushed out very fast.
If I turn my hearing off with my Life P2 in, they get pushed out, so I have to try to not do it when using wireless buds.
The chance one human only can do this is tiny, chances are many can, and chances are those who can are similarly assuming everyone can do it. So thought I’d flag it up to find out similar mutants.
I cannot turn off the low bass noise, so still like ANC headphones. These combined makes me deaf at will.
