I agree and think you should include the freqeuncy, wave lenght, explanation of how the sine wave graph of sound is actually a representation of air being pressed together in a longitudinal wave.you can talk about the nodes and anitnodes of the wave. How temperature and medium affect sounds waves. The doppler affect(why sirens sound higher pitched as they approache you.) Sound intensity, timbre, fundamental frequency, pitch,  resonance, ultrasonic and infrasonic sound, human hearin range, and human threshhold of pain. Any specific questions and i will glady answer i have also various equations you might like to have.</p></blockquote><p></p>
