Our ears can detect sounds that vibrate in the 20 to 20,000 Hz range. But sounds can vibrate at frequencies well beyond 20,000 Hz. Some bats can detect sounds as high as 200,000 Hz. Atoms vibrate as high as 10,000,000,000,000 Hz.

The lower range of sound, known as infrasound, vibrates as slowly as 0.001 Hz. Sources of such low frequency sounds include earthquakes, volcanoes, and lightning.

If our sense of hearing were not limited to our ear’s narrow band of detection, we would experience a world bursting with sound — from the powerful pulses of earth movements to the continuous vibration of the atoms.
