I wonder what makes somebody's cochlea hear more than another person.

I can hear the neighbors talking upstairs, but my brother hears nothing, I used to think he was little deaf, but now I know that I hear more distant sounds than other people.

This is not a good thing, because I'm not interested in the neighbors talk at all

It's a good question that I'm not sure I can answer. Human speech falls well within the range of human hearing. Possibly, your cochlea is more sensitive to sound volume. Do your ears hurt when you go to a concert with loud music?

A great help for my studies in Anatomy. Thank you for sharing.

In case somebody is interested, the tympanic duct along with the round window are needed for the perilymph to move freely. If the perilymph was to encounter a wall at the end of the vestibular duct or where the round window is, it would result in a hearing loss of 60 dB and over.

Good idea to take models and the laser pointer. An approach I have not seen yet.
