changes in mechanical pressure transmitted through solids, liquids and gases.
Two characteristics of sound waves
frequency and amplitude
refers to wavelength and is measured in hertz
the perceptual experience of sound wave frequencies
the ___of a sound wave determines its loudness
loudness is measured in?
the outer region of the ear that helps channel sound waves to the ear and allows you to determine the location of the sound
extends from the pinna to the eardrum,
malleus (hammer) incus (anvil) and stapes (stirrup)
The middle ear consists of 3 bones called ossicles
a fluid filled membrane that is coiled in a snail like shape and contains the structures that convert sound into neural impulses.
The ___ is the quality f sound waves that is associated with changes in pitch
The amplitude of a sound wave determines its loudness. ___amplitude sound waves are louder than ___ amplitude waves
Two ways we localize sound
First we take advantage of the slight time difference between the sound hitting both ears to estimate the direction of the source. Second, we use differences in intensity in which the sound is heard by both ears.
Place theory of hearing
how we perceive pitch Is based on the location along the basilar membrane that sound stimulates
the perception of pitch is related to the frequency at which the basilar membrane vibrates
The Primary Auditory Cortex
is a major perceptual centre of the brain involved in perceiving what we hear
The primary auditory cortex is found in which lobe of the brain?
Neurons cannot fire fast enough to keep up with the high pitched sound waves. Therefore, they alternate firing according to the?
a sensory system in the ear that provides info about spatial orientation of the head as well as head motion
structures that influence your ability to detect when your head is no longer in an upright position
