Audiology Praxis 5343 Questions And
Answers 100% Pass

What is the relationship between fundamental frequencies and harmonics? - answer✔F0=
lowest freq component of a complex periodic sound; harmonic is a regular and repeating
multiple of the f0
In which frequencies and at what intensities are most speech sounds produced? -
answer✔When applied to speech, the human voice spans a range from about 125Hz to 8kHz.
55-65 dB

Define threshold - answer✔"Threshold is defined as the lowest decibel hearing level at which
responses occur in at least one half of a series of ascending trials. The minimum number of
responses needed to determine the threshold of hearing is two responses out of three
presentations at a single level ."
What is the relationship between sound pressure level (SPL) and hearing level (HL)? -
answer✔dB HL normalizes SPL scale to 0 because we do not hear the same at all frequencies.
Our ears do not perceive low- and high-frequency sounds as well as they do sounds between
500 and 4,000 Hz. Thus, normal hearing, if plotted on an audiogram using the SPL scale, would
be a curved, wavy line.
Describe the function of each of the three major parts of the hearing mechanism -
answer✔OUTER: Pinna-- Funneling of sound & localization. Ear canal-- Amplifies sounds &
protects TM
MIDDLE: Reduces impedance mismatch & Protects from loud sounds (also, Eustachian tube
equalizes pressure BC for the TM to vibrate, the air pressure needs to be equal on each side of
the TM.)
INNER: amplify sounds, frequency selectivity, converts sound to electrical signal, maintain
balance

Function of outer and inner hair cells? - answer✔OUTER: Amplification of displacement on the
traveling wave & frequency selectivity (active processes are here)

INNER: Nerve excitation= send signals to auditory nerve

What are the fluids found in the labyrinths of the inner ear? - answer✔Scala vestibuli:
Perilymph
Scala media: Endolymph
Scala tympani: Perilymph

What impacts can hearing loss cause for learning in children? - answer✔Delay in speech and
language, reduced academic achievement and vocabulary, lessened literacy skills, social
isolation and poor self-concept, vocational choices
Describe the differences in speech and language development between pre- and post lingually
deafened children. - answer✔pre lingual- deafened before they learn speech
post lingual- deafened after they learn speech (about age 6)-effects are not as severe for post
lingually deafened children; need to implant/amplify immediately for prelingual

What impacts can hearing loss cause for adults (ex: social isolation)? - answer✔fatigue,
depression, social withdraw, impaired memory, reduced quality of life, headaches, increased
stress and blood pressure

What are the etiologies of hearing loss present at birth? - answer✔50% Genetic (syndromic &
Non-syndromic)
25% Environmental
25% Idiopathic

Genetic causes of HL? Non-syndromic and syndromic - answer✔Non-syndromic:
Connexin mutation related
BFN B4
Mitochondrial

Syndromic:
Alport syndrome
Branchio-oto-rental syndrome
CHARGE

Jervel and Lange-Nielson Syndrome
Pendred syndrome
Treacher Collins syndrome
Stickler syndrome
Ushers syndrome
Waardenburg syndrome
Down syndrome, Neurofibromatosis type 2

Environmental causes of hearing loss (pre/perinatal= present at birth) - answer✔TORCH
(toxoplasmosis, syphilis, HIV, herpes, rubella, CMV)
Premature birth, low birth weight, asphyxia
Maternal- pre-eclampsia, gestational diabetes, RH incompatibility
Fetal alcohol syndrome

Characteristics of waardenburg syndrome - answer✔pigmentation abnormalities (gray spots in
hair or different color eyes) and wide-set eyes, congenital SNHL, *can be progressive

Characteristics of Branchio-Oto-Renal Syndrome - answer✔Sensorineural, conductive, or mixed
& can be progressive or permanent at birth. Can cause ossicular fixation or cochear hypoplasia.
Kidney abnormalities!

Characteristics of CHARGE syndrome - answer✔Colomba of the eyes
Heart defects
Atresia or stenosis of the Chonae (nasal passage)
Retardation of growth/development
Genital abnormalities
Ear abnormalities/deafness

Stable, mixed severe-profound unilateral loss

Characteristics of Treacher Collins Syndrome? - answer✔Wonder movie. No cognitive delays!
Poor speech articulation. Moderate-severe CONDUCTIVE loss onlt (anotia/microtia, atresia)
