As the article says:

"We are less sensitive to low and high frequencies, we hear mid frequencies more prominently (especially between 1-5 kHz)
As the volume increases, this perceived loudness difference between the frequencies diminishes"

The human voice has an approximate range of 100 Hz to 5000 Hz. When I pump up the volume, I hear the music more and my wife less. smile

QED: Loud is good.
