Document Summary

Physical stimulus (matter or energy influencing the body) -> physiological response (chemical/electrical activity within the body) -> sensory experience (subjective sensation/psychological experience) Audition the sense or act of hearing. Properties of sound waves: frequency corresponds to our perception of pitch. Length of the sound wave; perceived as high and low sounds (pitch: amplitude corresponds to our perception of loudness. Height or intensity of sound wave; perceived as loud and soft (volume: complexity corresponds to our perception of timbre. Sound waves changes in air pressure unfolding over time. Oscilloscope an electronic laboratory instrument that traces a visible wave form. Amplitude the intensity or amount of energy of a wave. Get the rest on the power point. The ear: outer ear sound waves are collected. Helps pinpoint and locate sound: middle ear sound waves are amplified. Auditory canal where sound travels to reach eardrum. Inner ear sound waves are transduced into coded neural messages.
