auditory; chapter 12 Sensation and Perception

calculated

location cues are " "

elevation

y

distance

z

head related transfer function

the difference between the sound from the source and the sound actually entering the ears

HRTF

provides information for sound localization because the head an pinnae decrease the intensity of some frequencies and increase the frequencies of others

internalization

the perception that the sound is inside our head; occurs with earphone usage

binaural cues

not effective for judgements of on elevation since in many locations they may be zero

ITD

auditory system determines Azimuth based on " " regardless of frequency

acoustic shadow effect

higher frequency sounds elicit greater intensity differences between ears due to the " "

ILD

helps with localizing high frequencies

monaural

also needed for good sound localization

olivary complex

summation of binaural beats occurs where in the cortex?

greater

beat frequencies appear to have " " amplitudes

superior olivary complex and auditory cortex

have neurons that respond best to specific time difference between the sound in one ear and the time in the other

auditory cortex

damage to the " ", patients have difficulty localizing sound

false

humans localize based on topographic maps (true or false?)

what stream

responsible for identifying sounds, sound recognition

where stream

responsible for locating sounds, sound localization

precedent effect

judge sound location to be the source that is detected by the closest ear

1-5msec

at differences of " " we detect teh same sound

5msec

for sond differences great than " " we detect an echo

reverberation time

the amount and duration of indirect sound in a room, also known as the time it takes for the sound to decrease to 1/1000th of its original level (or 60dB)

muddled

if the RT is too long, the sound seems " "

dead

if the RT is too short, the sound seems " "

2

perfect RT for a concert hall

intimacy time

time between when sound arrives and when the first reflection arrives from indirect sound

3Hz

JND for pitch

timbre

eliminating the fundamental causes a change in " "

right

side of the brain especially critical for perceiving pitch

left

side of brain for processing rapid changes in frequency and intensity

second auditory cortex

central pitch processor; when damaged, causes tone deafness

rhythm

both left and right sides are necessary for complete perception of " "

synesthesia

when one sensation provides another, ie tasting blue, or hearing orange
