One of reasons people hears differently is there are natural sounds and un-natural sound. People can only hear one sound only either natural or un-natural sound. People can’t hear natural and un-natural sound at same time. Therefore, a’philes don’t like noise when they are listening audio music.The natural sounds (dog barking, blower sound, washing dishes, people voices) disrupt listening audio music (unnatural).
Listening unnatural sounds takes lots of brain processing and energy that it results "the listener’s fatigue." ex.) many people fall a sleep in Sunday worship. A’philes fall asleep while listening audio music.
For trained ears, they can hear both sounds in alternating manner (I guess alternating 5~10 times/second between 2 sounds). A’philes can alternating faster and easily than women. Therefore, women hear the audio music like the left spkr in below video.
