laptop with spectrum
analyzer software and microphone
206
DESCRIPTION
Charge the flash unit, then
fire it at the cymbal suspended near the microphones. A
faint ping can be heard. Use the spectrum analyzer to
show that the this is not just the "poof" sound from the flash
unit, but a "ping" at the expected frequency of the cymbal.
The "Soundcard
Scope" program can be used as a spectrum analyzer.
The graphs below shows the sound of the cymbal struck by hand,
and the sound of the cymbal due to the flash.
