SPAA 344 Exam 3 Questions And
Answers Latest Update | Solved
When do fetuses begin perceiving auditory stimuli ? CORRECT ANSWERS Several
Weeks
What are some developmental milestones for birth to 3 months? CORRECT ANSWERS
- reacts to loud sounds with startle, reacts to sounds that are close by, responds to low-
frequency sounds (vowels) better than high-frequency sounds (consonants), by 3
months recognized mothers voice
4-6 months CORRECT ANSWERS - turns eyes/ head to search for sounds, enjoys
hearing own sounds, enjoys sounds of musical toys, responds to voice (babbling),
begins differentiating sounds (environmental vs speech
When can we start preforming audiometry on the child? CORRECT ANSWERS 5-6
months
7-9 months CORRECT ANSWERS - in sitting position, turns eye/head/ body to sound
source, responses to simple requests, imitates speech and non- speech sounds,
responds to name, attends to music/ singing
10-12 months CORRECT ANSWERS - responds physically to music, responds to
questions by searching, can look for named objects that is out of sight, understands
some common phrases
What are the basic perception abilities? CORRECT ANSWERS Frequencies: 20-
20,000
Intensities: up to 130-140 dB SPL
What are acoustics of speech factors CORRECT ANSWERS 1.) Intensity Parameters
2.)Frequency Parameters
3.) Temporal Parameters
4.) Transitional Cues
True or False: in contrast to the human dynamic range of hearing, the range of intensity
of speech is relatively large CORRECT ANSWERS False (relatively small)
What is the mean SPL measures for faint speech 1 meter from speaker? CORRECT
ANSWERS 45 dB SPL /25 dB HL
What is the mean SPL for average speech 1 meter from the speaker? CORRECT
ANSWERS 65 dB SPL/ 45 dB SPL
, What is the mean SPL for loud speech 1 meter from speaker? CORRECT ANSWERS
85 dB SPL/ 65 dB HL
How much more energy does the weakest phoneme have? CORRECT ANSWERS 680
times
Do vowels or consonants have more energy? CORRECT ANSWERS Vowels have
more energy
Do male or female talkers have more energy CORRECT ANSWERS Males have higher
energy (3dB)
Where is the greatest amount of energy found in speech? CORRECT ANSWERS In
frequencies below 1000 Hz
What are the fundamental frequencies (F0) of human voice? CORRECT ANSWERS
Males (130Hz), Females (260Hz), Children (400Hz)
What are formants? CORRECT ANSWERS areas of energy concentration that result
from the resonance occurring in the vocal tract ( acoustic cues for vowel identification)
What are the spectral characteristics of vowels? CORRECT ANSWERS - Usually below
1000 Hz and usually have high intensity
What is perceptual training? CORRECT ANSWERS Training to address perceptual
deficits (enhance auditory and/or auditory - visual perceptual skills, must learn to use to
use degraded auditory input
What us auditory training? CORRECT ANSWERS -begins after fitting of appropriate
sensory aid
-develop ability to recognize speech using auditory signal and interpret auditory
experience
-learn to maximize use of residual hearing
What is speech reading training CORRECT ANSWERS Speech has both auditory and
visual components
- provides complementary information
- auditory : manner of articulation
-visual: place of articulation
- practice integrating two signals
What is auditory training a major component of? CORRECT ANSWERS Aural
Rehabiltiation
What are the goals of auditory training? CORRECT ANSWERS -to facilitate the optimal
use of HAs and CI (help to enhance residual hearing )
