Aural Assessment and Intervention Flashcards
Auditory system that is sensitive in the 500 - 4,000 Hz is an important element underlying the ______________ and ______________
Production and comprehension
True or False. A child with severe hearing loss will have difficulty decoding the sound signal, thus they will perceive words differently than normal hearing.
True
Children with hearing impairment learn speech discrimination and production by:
Watching how sounds look on the face
Vibrations
Distorted auditory signal → acoustic properties are incorrect
True or False. If a severe loss has been present since birth, normal acquisition of language is difficult.
True
True or False. If the age of onset is early and age of detection is late, specialized instruction and other interventions are necessary to develop speech and language. Such instruction may rely on visual, tactile, and kinesthetic cues and signing.
True
True or False. Children and adults with acquired hearing loss will retain speech sound production patterns for a time. However, when amplification is not present, their articulation skills deteriorate eventually.
True
According to Gold (1980) speakers with congenitally severe or profound hearing loss have _______ intelligibility
20% intelligibility
A person with hearing loss will have problems at both _______ and _______ levels.
Segmental and suprasegmental levels
Segmentals: errors on both consonant and vowels
Suprasegmental: Slower rate than normal-hearing speakers because of a longer duration during sound production
Most commonly seen speech errors seen in deaf speech
Errors of omission–omission of final consonants, /s/ in all contexts, initial consonants
Errors of substitution–voiced for voiceless consonants, nasal for oral consonants (hypernasal like), low feedback substitutions (substitution of sounds with easily perceived tactile and kinesthetic feedback for those with less; e.g., /w/ for /r/ substitution), substitution of one vowel for another
Errors of distortions–degree of force, hypernasality associated with vowel productions, imprecision and indefiniteness in vowel articulation, duration of vowels, temporal values in diphthongs
Errors of addition–insertion of a superfluous vowel between consonants, unnecessary of final stop consonants, diphthongization, superfluous breath before vowels
Speech sounds error patterns observed in both children who use hearing aids and children who use cochlear implants
Developmental patterns–assimilation errors, consonant cluster reduction, final consonant deletion, liquid simplification, palatal fronting, stopping, unstressed (weak) syllable deletion, velar fronting
Nondevelopmental patterns–initial consonant deletion, glottal stop substitution, backing, vowel substitution, diphthong simplification
For language form of a child with hearing loss
Sequence of phonemes roughly similar to that of hearing children
Protracted in development
More likely to produce voicing errors, extra nasality, and ICD
True or False. Early use of cochlear implants can alter the development trajectory → close to typical levels of receptive vocabulary.
True
True or False. In terms of language use, early exposure to language and communication in socially meaningful contexts is more important than hearing status per se.

Why do audiologists need to perform hearing measurement?
Purpose: describe what the patient hears and how they hear it, describe the communication ability, determining the site(s) of lesion(s) within the auditory system, basis from which a plan of habilitation can be developed
Vibrator placed behind the ear on the mastoid process rather than headphones. What conduction test is this?
Bone conduction test
True or False. Speech audiometry is an objective assessment.
False. Speech audiometry is a subjective assessment.
True or False. The stimulus used in speech audiometry are spoken materials that are provided at controlled sound pressure levels.
True
What is the speech recognition threshold (SRT)?
Minimum hearing level for speech at which an individual can recognize 50% of the speech material
Selects item from a closed set of choices
Repetition/indication of recognition 50% OTT
True or False. With SRT, spondee words are commonly used
True
