Hearing: a starting place

Physics Narrative for 11-14

Range of sounds

The range of sounds that humans are able to hear is impressively large, taking us from the loud roar of an aircraft as it makes its final approach on landing to the quiet murmur of the wind as it passes through the trees. Alternatively we might think in terms of moving from the low pitched rumble of distant traffic to the high-pitched screech of the dentist's drill.

We can consider these two ranges of our hearing as forming two sides of a box stretching:

  • From very quiet to extremely loud.
  • From a low-pitched rumble to a high-pitched squeak.
