True or False: Approximately 3 in 1000 children are born with congenital, significant permanent, bilateral hearing loss.
True
True or False: Every day about 33 infants are born each day in the United States with permanent hearing loss.
True

True or False: Hearing loss affets 12,000 children born in the United States each year, making it the most uncommon birth defect
False - Hearing loss affects 12,000 children born in the United States each year, making it the most common birth defect
True or False: Infants who spend time in the ICN (Intensive Care Nursery) during the newborn period are at a lower risk for hearing loss.
False - Infants who spend time in the ICN during the newborn period are at a higher risk for hearing loss
True or False: Since the initiation of hearing screening and EHDI prorams, the average of hearing loss identification has decreased to 2-3 months of age.
True
Fill in the blank: About 90% of children’s knowledge is attributed to ________ of sounds around them.
incidental reception
True or False: An estimated 5 million school days are missed every year due to otitis media.
True
True or False: All children will develop some period of hearing loss related to ear infections from birth to 10 years of age.
False- Nearly all children will develop some period of hearing loss related to ear infections from birth to 10 years of age
About what percent of children who receive hearing screenings at school fail because they can’t hear within normal limits?
A.) 5-10%
B.) 15-20%
C.) 10-15%
D.) 25-30%
E.) 35-40%
C - 10-15%
Be able to explain how we hear sound
Outer Ear (acoustic energy)
Middle Ear (mechanical energy)
Inner Ear (electro-chemical energy)
*Basilar Membrane
*Traveling Wave
*Responses of hair cells
Auditory Nerve (electrical energy)
Sound representation in the central auditory system
Outer Ear consists of these primary parts:
Pinna and Ear Canal
*outer 2/3 cartilaginous & inner 1/3 bone
Which of the following are roles of the Outer Ear?
A.) Protection of the middle and inner ear structures
B.) Amplifies high frequency sounds (OE resonance)
C.) Helps in determining where a sound is coming from
D.) A, B, and C
E.) None of the above
D - A, B, and C
The components of the middle ear are:
Ossicles, Oval Window, Eustachian Tube, Tensor Tympani Muscle, and Stapedius Muscle
The cochlea is divided into three components which are:
Scala Vestibuli, Scala Media, and Scala Tympani
True or False: The cochlea is snail shaped and has about 2 3/4 turns.
True
What are the classifications for types of hearing loss?
A.) Conductive
B.) Sensorineural
C.) Mixed Hearing Loss
D.) (Central) Auditory Processing Disorder
E.) All of the above
E - All of the above
The type of hearing loss that is caused by attenuation of sound as it travels from the outer ear to the cochlea.
Conductive Hearing Loss
Which of the following are some common causes of conductive hearing disorder?
A.) Atresia
B.) Middle Ear Anomalies
C.) Otitis Media with Effusion
D.) Excessive Cerumen
E.) All of the above
E- All of the above
*look at Table 2.1 on page 9 of book
This type of hearing loss is caused by a failure in the cochlear transduction of sound from the mechanical vibrations of the middle ear to neural impulses in the eighth cranial nerve
Sensorineural Hearing Loss
True or False: Conductive hearing loss will cause a reduction to sensitivity in higher frequency sound.
True - “A pathologic condition that affects the physical mass of the outer and middle ear mechanism will reduce sensitivity to higher-frequency sound
Which of the following are common causes of sensory hearing disorder?
A.) Inner ear anomalies
B.) Mumps
C.) Rubella
D.) Cytomegalovirus
E.) All of the above
E - All of the above
*look Table 2.2 for full list
True or False: Hearing sensitivity loss is the hallmark of a sensory disorder and ranges from mild to profound.
True
Which of the follwing are considered factors that can change the effect of hearing loss?
A.) Severity
B.) Configuration
C.) Duration
D.) Stability
E.) All of the above
E - All of the above
Severity, Configuration, Duration, Stability, Age of Onset
Chromosome are _______
strands of genes
Autosomes = ?? pair
22
*Sex chromosome 1 pair (23)
*Sums to a total of 46
This is the segment of DNA that controls protein synthesis
Gene
