Trial 1 - Messing Around

  1. Start the Sound Grapher. Figure out where the microphone is that picks up the sound.

  2. Make as many different kinds of sounds with your voice as you can -- loud and soft, high and low, different vowels, mouth open and closed. The sounds need to be steady so that you can see their pattern. Observe each sound with the Sound Grapher and think about how it looks. Use the Pause button to study each sound.
  3. Make a long aaaa sound (as in the word 'say'). Take a snapshot of the sound.


  4. Can you find a repeating pattern in the sound? What does the pattern look like? Use words and a drawing to describe the pattern.


  5. Now, make a long uuuu sound (as in the word 'moo'). Take a snapshot of the sound.


  6. Can you find a repeating pattern in the sound? What does the pattern look like? Use words and a drawing to describe the pattern.


  7. The two sounds you recorded are shown below. Is there a difference in the repeating pattern? If so, what is it? aaaa (as in say) uuuu (as in moo)


  8. Try creating another sound with the shape of simple wave. This is sometimes called a 'pure' sound. Take a snapshot of the sound.


  9. Now create a 'hissing' sound (shshshsh). Take a snapshot of the sound.


  10. Does the shshsh graph have a repeating pattern? If so, use words and a drawing to describe the pattern.


  11. Your uuuu and shshshsh sounds are shown below. How are the pictures different? uuuu shshsh


  12. Try several different sounds, with your voice, that make different patterns on the Sound Grapher. The sound should be steady to get a good picture.


  13. Choose one sound that you like. Take a snaphot of the sound.


  14. Describe the sound you made by thinking of a word that has the sound in it.


  15. Make a drawing of the repeating pattern.
