In this science project, a student chose to test students’ ability to hear sound in different ranges of pitch.
What group of frequencies do teenagers hear best?
Frequency played
Reactions of teenagers tested
Teenagers would hear the high frequencies best.
All of the subjects heard the high frequencies best.
All of the teenagers heard the high frequencies because the high frequencies played the loudest through the headphones.
I think that it was a little unfair, but I don’t think that there was anything that I could have done about it. The frequencies were so loud that people that weren’t wearing the headphones could hear them.
Valerie worked with a volunteer to determine which app would work best to play the appropriate ranges of pitch she had chosen and which headphones would work best.
She determined that she would need to decide when will this experiment be conducted and where, arrange a room so as not to disrupt class and get consent from students.
Prior to the experiment she needed to:
You could choose other frequencies to test.
