  1. Claire St. Louis – Warren Mott High School Natalie Steflja – Sterling Heights High School The Effect of Type of String, Length of String, and Diameter of Can on the Decibel Level of the Children’s Telephone-Can Game

  2. Overview • Introduction • Problem Statement • Materials • Procedures • Data Analysis • Conclusion • Further Research • Questions

  3. Definitions • Decibel • Frequency • Sound Wave • Tension

  4. Introduction • “Connecting people” and “Your world. Delievered.” – Nokia & AT&T. http://www.mycricket.com/community/cell-phone-info/3-most-common-problems-cell-phones

  5. What is the telephone-can game? • Two players. • Two cans connected by string. • One player speaks, other receives. • Sound traveled by waves through string. http://blog.orgsync.com/2009/adopting-technology-to-build-communities-around-residential-life/

  6. Traveling Sound Waves • Sound wave produced. • Sound waves vibrate across string. • Vibrate air, travel to ear, vibrate eardrum.

  7. Purpose • Test most effective combination: • Type of string. • Length of string. • Diameter of can. • Curiosity of researchers.

  8. Problem Statement • To determine the effect of type of string, length of string, and diameter of can on the decibel level of the telephone-can game played by children.

  9. Hypothesis • Standard string – kite string. • Shortest distance – 1 meter. • Smallest can diameter – 6.5 cm.

  21. Interaction Effects

  22. Interaction Effects • Type of String and Length of String (TL): -0.68 • Type of String and Diameter of Can (TD): -1.24 • Diameter of Can and Length of String (DL): 0.76

  23. Three Factor DOE

  24. Three Factor DOE Test of Significance Effect Effect2(90.486.1) Effect

  25. Conclusion • Effect of type of string. • Effect of length of string. • Effect of diameter of can.

  26. Conclusion • Reject hypothesis. • No significant relationship. • Outside factors affect data. • Background noise. • Tension differences. • Movement.

  27. Recap • Find most effective combination • Experiment conducted • Results obtained

  28. Further Research • Purpose due to pure curiosity. • Help parents and educators. • Different frequencies. • Change distance. • Test waxy strings.
