Document Summary
Chapter 11: sound, the auditory system, and pitch perception. Sometime sound refers to a physical stimulus (sound is pressure changes in the air or other medium), and sometimes it refers to a perceptual response (sound is the experience we have when we hear) The sound stimulus produced by a loudspeaker: Sound stimulus occurs when the movements or vibrations of an object cause pressure changes in air, water, or any other elastic medium that surrounds the object. Sound waves: pattern of alternating high- and low-pressure regions in the air as neighbouring air molecules affect each other, traveling at. Air pressure changes move outward from the speaker, the air at each location remains in approximately the sample place. Sound waves are invisible to our eyes, but they can sometimes be felt as tactile perceptions through the skin. Hearing is the predominant experience caused by sound waves. Specific perceptual experiences caused by sound waves are determined by the nature of the pressure changes.
