Vocal Acoustics and Measurement Techniques, Exams of Health sciences

Insights into various aspects of vocal acoustics and measurement techniques. It covers topics such as the typical range of variation for fundamental frequency (f0) during reading passages, the relationship between voice intensity and open quotient (oq), methods for direct measurement of lung pressure, the use of stroboscopy to simulate slow-motion vocal fold movement, the terminology used to describe the voice range profile (vrp), the best approach for computing jitter in a voice, the information provided by photoglottography, the limitations of the s/z ratio, and the factors that can lead to a decline in vocal efficiency. The detailed answers to the quiz questions demonstrate a comprehensive understanding of these vocal assessment techniques and their applications.

COMD 5070-chapter 5 quiz 3 -Answered
a typical range of variation for fundamental frequency (F0) during reading passages
would be about - ANSWER-3 semitones
as the voice increases in intensity - ANSWER-SQ increases and OQ decreases
direc measurement of lung pressure is achieved by - ANSWER-puncturing the neck
with a needle below the vocal folds
in stroboscopy of the vocal folds, slow motion movement is - ANSWER-simulated by
having sequential images taken successfully later across several vibratory
in the research literature, the voice range profile (vrp) has also been called the -
ANSWER-phonogram, phonetogram, F0-spl profile; all of the above
it best to compute jitter in a voice - ANSWER-during steady statw phonation
photoglottography - ANSWER-provides info about the relative glottal area
the s/z ratio - ANSWER-convenient and simple, but subject to variability in performance
the shape of the typical voice range profile reveals that - ANSWER-intensityand F0 both
tend approximately to rise together
vocal efficiency may decline in some disorders because - ANSWER-vocal fold closure
tends to be incomplete, leading to higher flow
