Hearing is the condensing of air molecules. c.i. Audition is touch at a distance. c.ii. Amplitude: how many air molecules c.iii. Pitch: frequency of the compression waves coming at you. d. When say two audio wavelengths hit the eardrum at the same time? d.i. The eardrum oscillates at a rate equal to the sum of the n number of wavelengths added together. e. Timbre: what makes musical instruments sound different from each other f. Fourier Analysis: you can break up a complex wave into the addition of sine waves. 2. Anatomy a.
