Document Summary
Similarities between vision and audition: both involve a sensory organ that take in stimuli from the outside world. Frequency is the inverse of wavelength: low frequency = long wavelength, high frequency = short wavelength. Sound can"t travel in a vacuum there is no sound in space (sound can"t travel) Sound travels through intervals of compression and refraction. Sound does not travel in linear direction occurs from a central source and travels outwards in all directions. Loudness of sound = amplitude measured in decibels (decibels = logarithmic: most peoples" hearing starts at about 4 decibels. Measure of complexity/purity = timbre: most sounds we hear on an every day basis are not pure-tones more complex sounds exist in the real world. Noise-induced hearing loss: over-amplification of sound can cause hearing loss. E. g. rock concert, classical music concert, opera. Your voice does not sound the same in a recording as it does in real life.
