And a nice teardown is done here, by the same guy: http://www.righto.com/2015/11/macbook-charger-teardown-surpr...

It depends. Played in an orchestra, and I've found out that hearing is very different from person to person. Seen people with hearing lower than 20Hz band, or people who can hear a wrong note in a symphony orchestra recording, or people who can perfectly tune their instruments by ear... The list goes on and on.
Our ears' equalizers are not always flat and equal. We can damage them yes, but not everyone starts from the same point.

This is called subsonic hearing, and it is not any blessing. Those who can hear frequencies lower than most often experience pain. It's the low frequencies coming from diesel school busses that are most painful to me, when no one else nearby can even hear the bus at all until it gets close enough. What the GGP is talking about is supersonic hearing, which often also includes that extra detail of pain.
