2025|COMPLETE EXAM TEST (questions and verified
answers) FREQUENTLY MOST TESTED QUESTIONS
|already graded A+|100% passed!!
What are the issues faced by those individuals with hearing loss? - (answers)1.
Decreased audibiility
2. Decreased dynamic range
3. Decreased frequncy resolution
4. Decreased temporal resolution
What does the term decreased audibility mean? - (answers)Decreased sensitivity
to sounds , poor thresholds ( elevated), reduced audibility for speech sounds
What does the term decreased dynamic range mean? - (answers)Decreased
number of dB levels between the softest sound you can hear ( threshold of
audibility ) and when sounds become painful ( level of discomfort) decreased
range of intensity levels that you can hear
What does the term decreased frequency resolution mean? - (answers)The clarity
between frequencies is decreased, decreased ability to tell one frequency apart
from another
What does the term decreased temporal resolution mean ? - (answers)Refers to
timing, trouble detecting , sensing the pauses between sounds and syllables
within words, between words in sentence, and voice onset time. Poor temporal
resolution leads to poor speech understanding because the person has trouble
distinguishing between parts of the sentences and words.

Damage to the outer hair cells causes what ? - (answers)OHC damage causes a
decreased sensitivity for soft sounds, - can hear less of the speech sounds in
higher intensities ( dB level)
—-because the OHCs sharpen the peak of the traveling wave for sounds <40 dB (
this means it won't vibrate the basilar membrane around that specific frequency (
sound) as much so that the sound can be discerned better by IHC) , and this
boosts these sounds ( increases the gain for these sounds) to allow the IHC to
sense these softer sounds ( increases the displacement on the basilar membrane)
How many rows or OHC and IHC and what happens if the OHC damaged ? -
(answers)3 rows OHC and if they are damaged decreased frequency resolution in
the frequencies associated with the area around the Level/part of the BM that
those hair cells served, would have trouble discriminating speech sounds and
frequencies in he prescience of others, and reduced /decreased audibility (
especially of soft sounds)-
Poor frequency resolution can lead to what - (answers)Poor temporal resolution
Without the outer hair cells what kind of hearing loss results - (answers)Moderate
cochlear hearing loss - a 40 to 60 dB loss ( because the outer hair cells boost
frequencies that are softer)
Electromotillity of the outer hair cells - (answers)OHC increase gain for softer
sounds and brain sends signals to the cochlea to do this, the OHC act as a cochlear
amplifier and they increase the displacement on the basilar membrane for softer
sounds
, 3
What are the high frequency components of speech vs. the low frequency
components of speech? - (answers)High frequency components - consonants (
weaker or softer than vowels)
Low frequency components - vowels
High frequency information is the most commonly missed
tonotopic organization of the cochlea - (answers)As you stimulate the cochlea the
basilar membrane areas respond (vibrate ) based on the frequencies that vibrates
best in that particular area of the membrane. Base - high frequency
Apex- low frequency
Basilar membrane is an overlapping series of band pass filters
What happens when high frequency information is missed what results? -
(answers)Speech is audible , but not intelligible because the consonants. ( high
frequency components help to make speech meaningful) , decreased intelligibility
of words
For 90 percent of adults and 75 percent of children with hearing loss , degree of
impairment worsens in which frequency range - (answers)500- 4K HZ
OHC loss results in - (answers)Attenuation, Decreased volume of soft sounds,
decreased audibility/sensitivity
IHC damage results in - (answers)Distortion , loss of clarity , distorts signal
completely
