Document Summary
Psyc 212 | chapter 5 the auditory system: sound and the ear. Used so that chemosensory information can be used for communication between animals. Is a distant sense stimulus can be detected from far away. Fastest among all sensory systems: the physics of sound. Sound must propagate through medium from its source. Mechanism to translate sound energy into a biological signal that ultimately produces hearing (aka our perceptual experience) Sound is caused by transmission of vibrational waves through a medium: Boyle"s bell jar experiment: sound produced by bell is less audible if in a jar in which air is slowly pumped out. Becomes silent when no air left in jar. Psychology definition: physical event that produced perceptual experience (hearing). Described by a set of qualities (loudness, pitch, etc ) since they are based on our perception. Physics definition: vibrational disturbance of a medium (medium can be solid, liquid, or gas); can be associated with physical qualities.
