Voice Science: Using Digital Tools to Explore Pitch and Amplitude 

written by Caroline Hall
consultant: David Straw

This interactive AAPT Lesson blends a cell phone oscilloscope app with a digital wave graphing activity from the Concord Consortium to explore how human voice patterns can be visualized as waves. Students will hum and sing various pitches and loudness, using microphones on their phones and computers. The digital tools transform the voice recordings into wave patterns. By viewing graphs of their own voices in real time, learners can deeply explore factors that affect amplitude, wavelength, pitch, and frequency of sound. The lesson can be adapted for both middle school and high school. Resource includes assessment with answer key and Student Guide.
