Ancestor Quote by Gordon Hempton
“The most sensitive frequencies are at the resonant frequencies of the auditory canal. In other words, the ear has shaped itself to naturally amplify certain bandwidth. And that corresponds to sounds in that bandwidth that were most important to our evolving ancestors to hear, in order to survive. And it doesn't match the human voice. It matches birdsong.”

Source Talk: Podcast Interview, The Sound of Evolution, 2019
The ear is tuned to amplify frequencies that were crucial for ancestral survival, which happen to align with birdsong rather than human speech.
In simple terms: Our hearing favors ancestral survival sounds.
