lecture 2: speech acoustics Flashcards
(29 cards)
why does Auditory Brain Change makes it difficult for the therapist to set appropriate goals?
hard to differentiate bw what’s a ABC behavior versus an inadequate auditory access behavior versus low compliance of CI use error
T or F: the brain prefers drill over meaning
false
does AR start with the hard stuff or the easy stuff? why? (2)
- start with the easy stuff to create positive and successful learning experiences
- success fertilizes the brain
the purpose of strategies and conditions in AR is for the therapist to get to the point of treatment where strategies and conditions are used _____.
sparingly
what is a cookie bite hearing loss? (3)
- better in low and high Hz, worst in medium Hz
- genetic
- progressive
how long does it take to “call the employees back” after being fitted with appropriate hearing tech?
- children: 3-6 months
- adults: 6-12 months
when is the best time for ID and tx?
before 6 months of age
T or F: cochlear implants can help restore synchrony even in diseased nerve
true
which frequencies are most impacted by OME?
high (and low, but not medium)
which part of the cochlea processes high frequencies? low frequencies?
- high: base
- low: apex
T or F: high frequency sounds can travel long distances
false – low can; high get tired after 6 inches
what is the range of speech frequencies?
50 Hz - 10K Hz (but most common = 250 Hz - 8K Hz)
formant frequency for:
a) men
b) women
c) children
a) 100Hz
b) 200Hz
c) 300Hz
F1 info = ____
F2 info = ____
- detection
- identification
- note: depends on HL; for reverse slope, it’s opposite
what is the auditory feedback loop?
three-part cycle that allows individuals to first speak, then listen to what they have said, and lastly, correct it when necessary
describe the frequency range for:
a) voicing
b) manner
c) place
a) 300Hz (nasal murmur = 250)
b) 500-1000Hz
c) 2000Hz
what are the sounds from the six-sound test in order of low to high frequency?
- mm (250-500)
- oo (250-500)
- ee
- ah
- sh (2K-4K)
- ss (4K-8K)
purposes of the six-sound test? (4)
- covers entire speech spectrum
- determines aud potential
- monitors hearing tech function
- helps design best tx plan
how many channels do today’s HA’s, CI’s, and BAHA’s have?
- HA: 16-24
- CI: 12-22
- BAHA: 12-16
what characteristics would someone have if they have inadequate auditory access to 250-500Hz? (6)
- weak/breathy/high voice
- nasalization/denasalization
- voiced consonant deletion
- vowel confusions
- nasal/plosive confusion
- voiced/voiceless consonant confusion
what characteristics would someone have if they have inadequate auditory access to 1000Hz? (5)
- quiet/loud voice
- poor pitch control
- omission of unstressed vowels
- omission of unstressed words
- vowel neutralization
what characteristics would someone have if they have inadequate auditory access to 2000-5000Hz? (5)
- voiceless consonant confusion
- poor production of high freq consonants
- vowel confusion
- omission of final consonants
- omission of markers for plurals/past tense/3rd person singular
if a HA has 10dB of gain and someone’s threshold = 50dB for a certain sound, at how many dB would that sound need to be presented at for them to hear it?
40dB
which frequencies gives info about prosody and suprasegmental patterns (stress, intonation)? (3)
- 250Hz = prosody + suprasegmentals
- 500 = suprasegmentals
- 1000 = suprasegmentals
