Pitch, Loudness and Timbre
The mechanism of human hearing does not operate as a perfect scientific instrument. What we hear as pitch, loudness, and timbre are quite subjective. But we are able to relate these subjective elements to quantifiable laboratory measurements of a sound wave's fundamental frequency, amplitude, and waveform respectively. This tutorial provides in-depth explanations that will allow teachers to integrate mathematics: 1) Measuring pitch of a musical note using a chart of fundamental frequency, 2) Using the Decibel Scale to measure sound intensity. It is highly recommended as content support for teachers and for use in high school algebra-based or AP physics courses.
