Chapter 2 Flashcards
What is a spondee?
A word with equal stress on each syllable
Speech reception threshold: The lowest presentation level for spondee words at which _ can be identified correctly
50%
Percentage of monosyllabic words presented at a comfortable listening level that can be correctly repeated by the patient… this score is called:
Speech Discrimination score
Speech discrimination scores are very helpful for determining appropriate _
Amplification
What are the 4 parts to the hearing aid fitting process?
Assessment
Selection
Fitting & Verification
Evaluation of Aided Performance
What are the five eras of hearing aid history?
Acoustic Carbon Vacuum tube Transistor Digital
What are the six hearing aid technologies?
Linear Analog with improved technology Programmable Programmable-digital True digital Beyond digital
What are the four noise reduction algorithms?
Modulation-based
Spectral Subtraction
Transient noise
Wind
What are the four types of mic sensitivity?
Omnidirectional
Cardoid
Hypercardoid
Supercardoid
What are the eight specialty hearing aids?
CROS, BiCROS, Multi-CROS, transcranial CROS, traditional bone conduction, bone anchored, middle ear implant, cochlear implant
Who uses disposable hearing aids?
Used for patients who do not ready to accept their hearing problem, or don’t want to pay the money
What are five reasons for binaural amplification rather than monaural?
Eliminate head show, improved hearing in noise (binaural squelch), localization, loudness summation, and wide dynamic range
REUR:
Real ear unaided response
REOR:
Real ear occluded response
REAR:
Real ear aided response
REIR:
Real ear insertion response
REIG:
Real ear insertion gain
RECD:
Real ear coupler difference
RESR:
Real ear saturation response
What do we look at on an audiogram when selecting amplification for a client?
Type, degree, configuration of loss, speech discrimination, loudness tolerance, tolerance of background noise
What do we look at on the ear when selecting amplification for a client?
Size, shape, anatomical irregularities
What are two types of assistive learning devices?
FM systems and sound field systems
What are the different mics for FM systems?
Lapel mic
Boom mic
Handi mic
Where can you use an FM system?
At home, at school, outside the home
Where can you use a sound field system?
Mostly used in classrooms
Go back to chapter 2 slides and study some of the terms in detail
Yep, do it
