The invisible world of vibrations, frequencies and sound

Frequencies are all around us; everything on this earth vibrates, and even you, right now, are resonating at a frequency between about 5 and 10 hertz. And if all things resonate, then surely they must also be making a sound... so what would that sound be? It's a question that musician, composer and TV presenter, Richard Mainwaring, has been pondering. In his new book Everybody Hertz: The Amazing World of Frequency, from Bad Vibes to Good Vibrations, Richard Mainwaring uncovers those mysterious sounds, and investigates how vibrations affect pretty much everything we do.
