To learn more about this topic, start your googling with these keywords:

  • Decibels (dB): a unit used to measure changes in pressure or power.
  • Loudness: the intensity with which a sound is perceived.
  • Weighted decibels (dBA): decibels that try to take into account our sensitivity for different frequencies to better approximate loudness.
  • Frequency: the rate at which something occurs. In the context of sound it usually means 'sound waves per second'.
  • Audible: perceptible for the human ear.
  • High sound: a sound that has a high (fast) frequency
  • Low sound: a sound that has a low (slow) frequency
  • Resonance: When multiple things have a similar frequency they will tend to move together and amplify each other.
  • Echolocation: Using sound to "see". Bats use this to hunt in the dark.
  • Equal loudness contours: Curves that show the sensitivity of the human ear along the frequency spectrum.
