25
what happens when early identification does not occur or when intervention efforts are ineffective?
hearing loss likely will result in delayed receptive and expressive speech and language development
26
what four aspects can speech and language delay associated with hearing loss can include?
semantics grammar phonology pragmatics
27
how is hearing loss in children and adolescents typically is classified?
etiology manifestation impact severity
28
When congenital loss is present, about _____% of the cases result from genetic causes.
50
29
what are other causes can children can experience congenital hearing loss?
infection, injury, or illness in the prenatal, perinatal, or postnatal periods
30
true or false: less common than biologically based loss, exposure to noise in the environment can result in a noise-induced hearing loss
true
31
what is more problematic than a loss in acuity?
decrease in auditory comprehension of spoken language and speech perception
32
Definition of threshold of hearing
the earliest point at which a person can begin to hear
33
true or false: threshold of hearing becomes lower as hearing loss becomes more severe
false - threshold becomes higher as hearing loss becomes more severe
34
Definition of audiogram
a graph plotting hearing level in decibels
35
two characteristics of conductive hearing loss
loudness of the sound is attenuated some auditory information may be lost
36
true or false: conductive hearing loss usually is amenable to medical or surgical intervention and therefore often is temporary
true
37
in children the most common cause of conductive hearing loss
otitis media - middle ear infections
38
three characteristics of sensorineural hearing loss
decrease in overall loudness decrease in speech perception decreased ability to distinguish speech from background noise
39
what is the most common type of hearing loss?
sensorineural hearing loss
40
true or false: sensorineural hearing loss can be treated effectively with amplification or other types of intervention, but hearing cannot usually be restored
true
41
true or false: most often, sensorineural hearing loss is not present at birth as a congenital hearing loss
false - it is present at birth
42
characteristics of mixed hearing loss
permanent reduction of sound additional temporary loss of hearing from the conductive component
43
how is pediatric hearing loss identified?
referral screening Comprehensive Audiological Evaluation Objective Measures
44
Definition of Comprehensive Audiological Evaluation
Assesses the type and severity of loss (mild to profound), speech discrimination and auditory perception abilities in quiet and in noisy conditions, and the cause of any loss
45
Definition of Typanometry
examines tympanic membrane movement and graphs the results on a tympanogram
46
Children with _____ hearing loss will have ______ tympanograms.
conductive; abnormal
47
When a ____ hearing loss is present, the tympanogram should be ____.
sensorineural; normal
48
three amplification and Listening Devices
hearing aids assistive Listening Devices (ALDs): cochlear Implants
49
Definition of FM system
most common ALD used by children is a personal amplification system that can be used independently or with hearing aids
50
Definition of cochlear Implants
a surgically Implanted device that provides direct electrical stimulation to the auditory nerve
51
when are cochlear Implants appropriate for children?
when they have severe to profound sensorineural hearing loss
52
Definition of aural habilitation
individualized intervention to achieve fluent communication in a manual or oral modality
53
what are three principles commonly used for all children?
ensuring an appropriate listening environment maximizing audition supporting listening development
54
what are five principles commonly used for young children?
early intervention parental involvement naturalistic environments social interaction functional outcomes
55
what are three principles commonly used for school-aged children?
effective means of communication self-advocacy literacy
56
Definition of auditory processing disorder
a type of hearing disorder that adversely affects an individual's processing or interpretation of auditory messages
57
true or false: APD is not typically accompanied by a loss of hearing acuity
true
58
true or false: children with APD typically have trouble with speech production
false - speech production is intact
59
symptoms of children with APD
academic and communicative difficulties inability to follow complex verbal directions spelling and reading deficits inability to engage in classroom discussions
60
true or false: amplification through hearing aids is not an option for children with APD
true
