When Ticks Become Tones

If a repeating pulse happens slowly enough, we perceive each pulse as a distinct pulse. But as the repeat rate is increased, the pulses start to merge into a steady tone. The "frequency" of the tone is the number of pulses per second.

 To do:

  • Move the octave fader slowly to the right.
  • Note the frequency range at which the individual pulses merge into a tone.
