Praxis 5343 Audiology Exam Questions

and Answers 100% Solved | Graded A+


What is the relationship between fundamental frequencies and harmonics?

- ✔✔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? - ✔✔When applied to speech, the human voice spans a range

from about 125Hz to 8kHz. 55-65 dB

Define threshold - ✔✔"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)? - ✔✔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 - ✔✔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? - ✔✔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? - ✔✔Scala

vestibuli: Perilymph

Scala media: Endolymph

Scala tympani: Perilymph

What impacts can hearing loss cause for learning in children? - ✔✔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. - ✔✔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)? -

✔✔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? - ✔✔50% Genetic

(syndromic & Non-syndromic)

25% Environmental

25% Idiopathic

Genetic causes of HL? Non-syndromic and syndromic - ✔✔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) -

✔✔TORCH (toxoplasmosis, syphilis, HIV, herpes, rubella, CMV)

Premature birth, low birth weight, asphyxia

Maternal- pre-eclampsia, gestational diabetes, RH incompatibility

Fetal alcohol syndrome
