PSY 111 Lecture Notes - Lecture 11: Stirrup, Psy, Stimulus Modality
Document Summary
Frequency number of sound waves or cycles per second (hz = one cycle per second) Amplitude vertical size of the sound waves (decibels db) Transduction system of ear is made up of bones, membranes, and tubes. Sound waves vibrate eardrum, which vibrates three bones (hammer, anvil, and stirrup) Amplify sound waves more than thirty times tissue) Cochlea coiled, snail shaped tube that contain basilar membrane (sheet of. Organ of corti rests on the basilar membrane. Has thousands of tiny hair cells that are actual sound receptors. Sound waves cause waves in liquid, which bend hairs, causing release of. Sound localization ability to notice location of sound due to timing difference in sound neurotransmitters wave reception in ear. Conduction deafness problems involving the mechanical system that transmits. Nerve deafness caused by damaged receptors within the inner ear, or damage to sound waves to the cochlea the auditory nerve. Taste (gustation) and smell (olfaction) are sensitive to chemical molecules rather than energy.
