Document Summary
Sound waves: are the result of a pressure fluctuation caused by the pulling apart and pushing together of air molecules. This has a specific amplitude and frequency: amplitude: the degree of variation in air pressure from neutral to higher/lower, felt as loudness. The higher the amplitude, the louder an object will be: frequency: the speed with which the wave travels, felt as pitch. The faster the frequency, the greater the pitch. Calculating frequency: frequency is measured in terms of the number of cycles per second, measured in hertz (hz). Each simple wave has a frequency that is a whole multiple of the fundamental: harmonic: is each simple wave that has a complex wave; waves at certain frequencies. Spectrogram: is a representation of speech sounds which can show the time on the y-axis, frequency of the x-axis, and the intensity by the representation of darkness.
