I don't hear a single sound.

  It's probably your speakers. A human can certainly hear 52Hz, mains hum is 50Hz (or 60Hz if you're in North America) and clearly audible.

    Quite true. It's also not uncommon to end up with harmonics of mains hum (at 120 Hz), which is more noticeable to human hearing than 60 Hz.
