Document Summary

Frequency: the number of wave lengths that pass by a given point in an amount of time: hertz: cycles per second of frequency, pitch: the perception of sound wave frequency. Amplitude: the amount of change that a wave undergoes during one cycle. Highest and lowest pressure: loudness: the perception of amplitude. Fundamental frequency: the lowest frequency produced by a vibrating object. Vibration along the entire length of the string. Overtones: frequencies higher than the fundamental that are also produced by a vibrating object. Vibration at half length, third, etc. length: timbre: the perception of sound wave complexity. Periodic sound: a sound with a regularly repeating pattern. Aperiodic sound: a sound with no regularly repeating pattern. A fluid filled tube that curls like a snail. Basilar membrane: a structure that extends the inside length of the cochlea and divides in two: covered in hair cells: sensitive to movement in cochlear fluid.
