When someone pretends that they're a physicists and through their work they determined that we perceive certain frequencies as louder or quieter when the actual loudness of the sound goes up or down.
Wow that guy is using "The Baxter-O'brien Maneuver" He's not a physicists who stumbled upon that phenomenon! That was Harvey Fletcher and Wilden Munson. This guy is just a nerd who lies. I cant believe he's really using The Baxter-O’brien Maneuver
