Document Summary
Tree falling in forest makes a sound regardless of who is around to hear it: result of sensory processing. Tree falling in forest doesn"t make a sound unless someone hears it. Just as visual system can interpret light waves to collect info about environment"s stimuli, auditory system translates sound waves from vibrating objects into psychological experience known as audition. Psychological point of view: fallen tree -> sound waves: sound waves -> no sound if no auditory system present to translate them into auditory perceptual experience. Sound is the result of our interpretation of waves (result of sensory processing) Module 2: the auditory mechanisms of different species. Cross-species variation based on specific needs (communication distances, mediums, what frequency needs to be received, etc. ) Different species develop different auditory mechanisms through process of evolution. Hearing abilities among species differs in the range of frequencies detected: eg: dog whistle -> doesn"t produce audible sound to human ear but does to dog"s attention.
