Why hearing is important in children Flashcards
Hearing loss is a ____ _____ ____ disability
silent developmental hidden
approx 12,000 new babies w/ hearing loss are
identified each year
another 4,000 to 6000 infants and young children between birth and 3 years of age who had passed the new born hearing screening test acquired
late onset hearing loss
Know some risk factors for hearing loss
family history of hearing loss
genetic disorders or syndromes
Why hearing is important?
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
deaf children born into hearing family, in absence of intevention
- does not learn to interpret sound patterns
- does not learn to produce sounds of spoken language around him/her
- unable to hear speech
- unable to acquire spontaneous language
what is the role of pediatric audiologists?
prevent
evaluate
intervene
What are the 5 core audiological services
hearing screening
objective testing
behavioral testing
amplification
aural rehabilitation
challenges in pediatric audiology (6)
- identifying hearing loss early
- understanding the impact of minimal or unilateral hearing loss
- accurately assessing hearing thresholds
- providing effective counseling to caregivers
- minimizing the effects of auditory handicap
- ensuring proper follow up for hearing impaired patients
any undetected hearing loss of any degree can have a significant impact on ?
speech, language, cognitive, and psychosocial development
Impact of mild hearing loss:
Overall impact
communication, language learning, and educational achievement are affected
Impact of mild hearing loss:
Perception of speech sounds
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
Impact of mild hearing loss
Educational and behavioral impacts
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
Impact of moderate hearing loss
speech perception
miss most conversational speech sounds, vowels are heard better than consonants. Short unstressed words and word ending (-s,-ed) are particularly difficult to hear
impact of moderate hearing loss
communication confusion
reduced auditory cues can lead to confusion in distinguishing speech sounds and word meanings
impact of moderate hearing loss
speech articulation
speech articulation often characterized by omission and distortion of consonants, strangers may have difficulty understanding their speech
Impact of moderate hearing loss
behavioral and learning impacts
may demonstrate behavioral problems, inattention, language delay, speech problems, and learning problems
impact of severe hearing loss
speech and language development
language and speech do not develop spontaneously without intervention .
With early intervention, proper fitted hearing aids, and specialized education, children achieve significant functional improvement
impact of severe hearing loss
auditory perception without amplification
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
Impact of severe hearing loss
more challenges
significant language problems speech problems and associated educational problems
impact of profound hearing loss
language and speech 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
impact of profound hearing loss
auditory perception without intervention
cannot hear or understand sounds, amplification is critical. Early detection and treatment significantly improve outcomes
impact of profound hearing loss
speech characteristics
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
communciation
vocabulary
sentence structure
speaking
