Document Summary

Psyc 100 week 10: sound is a wave. The amplitude of a sound wave determines the sounds" intensity; intensity is measured in decibel. Frequency: the# of peaks of a wavelength. Most of sounds consist of different frequencies, which can be shown on a spectrum (a graph showing the different frequencies) Loudness timbre color brightness saturation the higher the frequency the louder the sound jumping hair just-notice difference: minimum level of detectable difference in the magnitude of a stimulus. Harmonics: series of tones whose frequency is a multiple of the fundamental frequency: pattern recognition: identification of particular sound sources by the auditory system, characteristic of sound. Olfactory mucosa: mucous membrane lining the top of the nasal sinuses that contain the olfactory receptors. Olfactory mucosa project their axons into the olfactory bulbs (stalk-like structure located on the underside of the frontal lobes that contain neural circuits that perform the first analysis of olfactory info) in the brain.
