Q

Why hearing is important?

A

Speech and language development is critical and is considered as a prerequisite for cognitive development suggesting that appropriate intervention is crucial to facilitate this process.

HL not detected or treated, it can affect language development, school successfulness etc.

it affects many aspects of an individuals life
not just hearing and the ear

Q

perception of speechh sounds with a mild HL

A

Vowel sounds are heard clearly but voiceless consonants may be missed. The louder voiced speech sounds are only heard. The short unstressed words and less intense speech sounds (such as voiceless stops and fricatives) are inaudible.

Q

Educational and behavioral impacts of mild hL

A

In children with this degree of hearing loss auditory learning dysfunction may result in inattention, classroom behavior problems and possible mild language delay and speech problems.

Q

what is the impact on speech perception of a moderate HL

A

Miss most conversational speech sounds; vowels are heard better than consonants. Short unstressed words and word endings (-s, -ed) are particularly difficult to hear.

23
Q

Communication Confusion of moderate HL

A

Reduced auditory cues can lead to confusion in distinguishing speech sounds and word meanings.

24
Q

speech articulation of moderate hl

A

Speech articulation often characterized by omission and distortion of consonants. Strangers may have difficulty understanding their speech.

25
Q

behavioral and learning impacts of moderate hl

A

May demonstrate behavioral problems, inattention, language delay, speech problems, and learning problems.

26
Q

impact of severe hl on speech and language development

A

Language and speech do not develop spontaneously without intervention. With early intervention, properly fitted hearing aids, and specialized education, children can achieve significant functional improvement.

27
Q

auditory perception w/out amp with severe hl

A

Cannot hear typical sounds or normal conversation; can hear distorted self-vocalization, very loud environmental sounds, and only the most intense speech at close range.

28
Q

Significant language problems speech problems and associated educational problems.

A

severe hl

29
Q

impact of profound hl on speech and language

A

Delays: Severe language delays, speech problems, and potential learning dysfunction without intervention. Intensive special education with powerful hearing aids or cochlear implants is essential for language and speech development.

30
Q

Auditory Perception Without intervention with profound hl

A

Cannot hear or understand sounds; amplification is critical. Early detection and treatment significantly improve outcomes.

31
Q

speech characteristics of profound hl

A

Speech often includes issues with voice, articulation, resonance, and prosody. Vocal pitch may be higher, with a monotone quality due to lack of intonation and stress.

32
Q

what are communication parts affected by hl

A

vocab
sentence structure
speaking

33
Q

Children with hearing loss have difficulty with all areas of academic achievement, especially

A

reading and mathematical concepts.

34
Q

children with mild to moderate hearing losses, on average, achieve one to four grade levels lower than their peers with normal hearing, unless appropriate management occurs

A

true

35
Q

Children with severe to profound hearing loss usually achieve skills no higher than the ______ -grade level, unless appropriate educational intervention occurs early.

A

third- or fourth

36
Q

The gap in academic achievement between children with normal hearing and those with hearing loss usually widens as they progress through school.

A

true

37
Q

social functioning in children with HL

A

Children with severe to profound hearing losses often report feeling isolated, without friends, and unhappy in school, particularly when their socialization with other children with hearing loss is limited.

These social problems appear to be more frequent in children with a mild or moderate hearing losses than in those with a severe to profound loss.

38
Q

economic burden of hearing loss

A

Medical and audiological expenses
Education and training expenses
Special living expenses
Lifetime loss of income considerations

39
Q

what does research tell us about HL

A

Many deaf children have difficulties in large social settings . They cannot attend to multiple simultaneous conversations, especially when there is background noise

Joining an existing group of peers and maintaining play behaviours with them is socially challenging

Deaf children often have an inadequate concept of how others think and feel

40
Q

How do we typically define minimal and mild hearing loss for kids?
why is this different than adults?

A

normal - -10-15
minimal/slight - 15-25
mild - 26-40

they already have their s/l development but children have not so the loss really matters

41
Q

The category of minimal hearing loss is broad, severity and configuration are also important.

A

true

42
Q

he most commonly accepted definitions of minimal and mild hearing loss were proposed by the Centers for Disease Control (CDC) Early Hearing Detection Intervention Program
unilateral hl

A

Unilateral hearing loss: PTA (0.5, 1, 2 kHz) is ≥ 20 dB HL, with no more 10 dB ABG at 1, 2, and 4 kHz in the impaired ear. AC thresholds are 15 dB or better in the other ear.

43
Q

he most commonly accepted definitions of minimal and mild hearing loss were proposed by the Centers for Disease Control (CDC) Early Hearing Detection Intervention Program
bilateral snhl

A

both ears have average AC thresholds between 20-40 dB HL and average ABG ≤ 10 dB 1, 2, and 4 kHz.

44
Q

the most commonly accepted definitions of minimal and mild hearing loss were proposed by the Centers for Disease Control (CDC) Early Hearing Detection Intervention Program
HF SNHL

A

in or both ears, AC thresholds >25 dB HL at two or more frequencies above 2 kHz (3, 4, 6, or 8.0 kHz) with no more than 10 dB ABGs at 3 and 4.0 kHz.

45
Q

Studies showed that by the time children reach school age, the prevalence of minimal hearing loss increases from approximately

why a huge increase?

A

0.03% to about 1% to 14%

because they do school screenings and progressive hearing loss- even if they pass NBHS doesn’t mean they wont develop hl later on so why the numbers get larger during school age

46
Q

Why is there such a large discrepancy in prevalence rates of minimal hearing loss from birth to school-aged children?

A

school screenings

47
Q

could miss 60% of case with slight/minimal HL because

A

we screen at 20/25dB

48
Q

Hearing screening programs do not target minimal and mild degrees of hearing loss, these children are not likely to be referred for diagnostic evaluations.

A

true

49
Q

Real-world outcomes for children with minimal hearing loss

A

50% of children either repeat a grade or need resource support in school
Increased behavioral and linguistic problems compared to hearing controls.

Children with minimal SNHL experienced more difficulty than NH children on a series of educational and functional test measures.

50
Q

% of children with minimal SNHL had failed at least one grade.

A

31

51
Q

what to expect with minimal hl children

A

they are more likely to repeat a grade, linguistic issues, behavioral issues & educational and functional test measures will be flagged as delayed on those tests

52
Q

are there differences bw audiologist with fitting amp with unilateral loss

A

yes
Inconsistent practice from audiologists who recommended amplifications in 60.1% of children with mild loss and 26.1 % of those with unilateral hearing loss.

53
Q

minimal hearing loss needs _____ SNR

A

higher

54
Q

Why may a 15 dB hearing loss result in language delay?

A

Nature of speech sounds!
Major amount of speech energy reside in the voiced vowels and consonants.
The unvoiced consonants /s, p, t, k, th, f, sh/ contain so little speech energy that they often fall below even normal hearing thresholds in an average rapid conversation.
