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 _

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
