When I scrunch my eyes and slightly clench my teeth, I hear a moderately loud rumble. As a kid, would swim to bottom of our public pool (12 ft) and recover coins and other items. Not sure if this may have affected my hearing but I thought others might be able hear me do. I think this may have been when I discovered this capability. Given the low frequency, fantasized I was Aquaman!
A member poll may be interesting but wonder whether it may be difficult for folks to understand how to reproduce. In my case, am thinking I may just have an audiologist test me. Personally am more interested to know whether this ability introduces some major difference in my hearing vs the general population.
Has anyone here had a hearing test and found unusual results?
