Document Summary
Study guide for exam #2: the auditory system: physics of sound, terminology, and. Physics, terminology, and fourier additivity (quantitative realist perspective) Physical definition of sound (compression and rarefaction of air). Sound: flunctutations of pressure. sound waves are defined by the frequency, intensity (amplitude), and phase of fluctations. sound frequency and intensity correspond to our perceptions of pitch and loudness respectively. Compression: waves that have the same direction of oscillation or vibration along thier direction of travel which means that the oscillation of the medium (particle) is in the same direction or opposite direction as the motion of the wave. Rarefaction of air: the reduction of a medium"s density or the opposite of compression. Rarefaction can be eaisly observed by compressing a spring and releasing it. Physics terms and relationships: [e. g. frequency=f, wavelength= , velocity=v; f =v/ ]. Wavelength is the distance sound will travel while one cycle of the sound occurs. (in meters)
