4) Listen to these two sounds. Of which does the sound wave have a higher amplitude?
Sound A
Sound B
  • Make sure to be in presentation mode.
  • Click the icon to play the sound.
  • Make sure to keep the volume of your computer the same!

Slide 15 - Slide

4) Listen to these two sounds. Of which does the sound wave have a higher amplitude?
Sound A
Sound B
  • Make sure to be in presentation mode.
  • Click the icon to play the sound.
  • Make sure to keep the volume of your computer the same!
The soundwaves of sound B have a higher amplitude, because the sound is louder.
