25
Saccule and Utricle system is activated by what?
by linear accelerations
26
VOR - Vestibulo- ocular Reflecx
VOR cause eyes to move towards the side that is sending a stronger signal - stabilizes our vision by offsetting head movement, allowing your vision to remain fixed
27
Is excitation from the left side or right
left side
28
is inhibition from the left side or right
right
29
What are the three semicircular canals
superior canal posterior canal lateral canal
30
Sine Waves or sinusoids represent pure tones
analysis of complex sounds (Fourier analysis) clinical audiology tests
31
Simple harmonic motion is also known as ... and it generates ...
sinusoidal motion and it generates a sine wave
32
upward part of sine wave (in the positive) is what? (compression? rarefaction?)
compression (of air molecules)
33
relationship between two identical sine waves that are displaced in time
Phase
34
Sine waves and other waves that repeat themselves over time are called
periodic
35
one complete replication of a periodic wave
cycle
36
time it takes to complete one cycle
period (t)
37
of cycles that occur per second
frequency (f)
38
distance travelled by the wave in 1 period - distance covered by one cycle
Wavelength
39
As frequency increased the period and wavelength of a sine wave ...
decreases
40
What is the relationship between period and frequency
inverse
41
true or false - when the period is shorter less cycles can fit into one second
f - MORE cycles can fit into one second
42
true or false - shorter periods of rarefaction and condensation result in higher frequencies
true
43
... refers to the size or magnitude of a sine wave
Amplitude
44
When two waves are exactly in phase
Reinforcement /constructive interference
45
when the two waves are exactly out of phase (180 degrees) the amplitude of the combined waved is zero
Cancellation/Destructive Interference
46
combination of two or more pure tones with different frequencies
complex wave
46
Aperiodic
Does not repeat itself over time
47
fundamental frequency
lowest frequency component of a complex periodic wave
48
harmonic
integer (whole number) multiple of the fundamental frequency
49
is 0 dB HL normal human hearing
yes
50
true or false - you can't have negative on the dB HL scale
false
51
SLM- Sound level meter
pick up sounds of all frequencies within a certain range determines magnitude of the sound
52
Divides right from left- Midsagittal place= midline
Sagittal Plane
53
Divides top from bottom horizontal plane
Transverse Plane
54
is dextral right or left
right
55
is sinistral right or left
left
56
shorthand for right ear is Auris Dextra or Auris Sinistra
auris dextra
57
shorthand for left ear is Auris Dextra or Auris Sinistra
Auris Sinistra
58
is rostral towards the head or towards the tail
towards the head
59
is caudal towards the head or towards the tail
towards the tail
60
divides front from back
coronal plane
61
dorsal is to the back or toward the belly
back
62
ventral towards the back or towards the belly
belly
63
collects sound and funnels it to the tympanic membrane (eardrum) changes the spectral (frequency) characteristics of sound which aids in sound localization
Outer Ear
64
Sound wave cause eardrum to vibrate setting the bones in the middle ear into motion
Middle Ear
65
Turns mechanical vibrations into neural signals sorts sounds into different frequencies Neural signals are sent from auditory nerve to the brain
Inner ear (cochlea)
66
What surrounds the ear canal, middle ear, inner ear
the temporal bone
67
what do the squamous, petrous, mastoid, and tympanic make up
temporal bone
68
thin and fan -like lateral aspects of the bone lies anterior and superior to the ear canal
squamous portion
69
posterior portion of the bone lies posterior to the ear canal contain air cells extends posteriorly from petrous portion, below and behind the squamous portion
mastoid portion
70
forms the inferior and anterior walls of the ear canal inferior to the squamous and petrous portion and anterior to the mastoid portion
tympanic portion
71
pyramid shaped projects medially from the other 3 portions only visible in medial view contains sensory organs of hearing and balance, and the internal auditory canal
Petrous portion
72
location of sound source in the horizontal plane
azimuth
73
location of sound in the vertical plane
elevation
74
Head- Related Transfer Function (HRTF)
shows changes in sound level due to the presence of the head, pinna, and ear canal, as a function of frequency
75
Ear canal has a resonant frequency of 3000-4000 Hz
results in a gain in sound amplitude in that frequency region boost of as much as15-20 dB
76
Head shadow effect
high frequency sounds have wavelengths that are smaller, so they cannot bend around the head
77
Interaural Time Difference
Sound will arrive to the nearer ear sooner than the far ear occurs at all frequencies
78
Pinna Effect
diffraction and reflection of sound waves by the pinna modify the transmission of high frequency sounds
79
binaural cues
are used as sound localization when two ears are present
80
is this interaural level differences or interaural time differences when spl at near ear is greater than at far ear due to head shadow effect, exits for high frequencies
interaural
