QUESTIONS WITH SOLUTIONS GRADED A+
◉ How do acoustic measures help describe severity objectively?
Answer: They standardize ratings of speech disorders, reducing
variability among clinicians' assessments.
◉ What can acoustic measures track over time? Answer: They can
track progress and demonstrate treatment efficacy.
◉ What does EBP stand for in clinical practice? Answer: Evidence-
Based Practice.
◉ Why is it important to have hard data in speech therapy? Answer:
It helps to accurately measure progress and avoid misjudging
improvements based on familiarity.
◉ What is biofeedback in the context of speech therapy? Answer: It
provides real-time data to clients about their speech patterns, aiding
their understanding.
◉ How does sound travel through air? Answer: A structure vibrates,
causing air molecules to push and pull on each other, transferring
energy.
,◉ What happens to air molecules during sound transmission?
Answer: They move back and forth around their original position,
creating compressions and rarefactions.
◉ What is the difference between simple and complex sound waves?
Answer: Simple sound waves are pure tones with constant rates,
while complex sound waves are combinations of multiple
frequencies.
◉ What are transverse waves? Answer: Waves that travel across the
surface of a medium, like ripples on water.
◉ What are longitudinal waves? Answer: Waves where the medium
moves parallel to the direction of the wave, like sound waves in air.
◉ What are compressions in sound waves? Answer: Regions where
air molecules are pushed together, increasing pressure.
◉ What are rarefactions in sound waves? Answer: Regions where air
molecules are stretched apart, decreasing pressure.
◉ What is the human hearing frequency range? Answer: From 20 Hz
to 20,000 Hz (20 kHz).
, ◉ How do you calculate the period from frequency? Answer: Period
(seconds) = 1 / frequency (Hz).
◉ What is the relationship between frequency and period? Answer:
Higher frequency corresponds to a shorter period, and lower
frequency corresponds to a longer period.
◉ What is wavelength? Answer: The distance from one peak of a
wave to the next peak.
◉ How does frequency affect wavelength? Answer: Low frequency
results in longer wavelengths, while high frequency results in
shorter wavelengths.
◉ What is the formula for calculating wavelength? Answer:
Wavelength = speed of sound / frequency.
◉ What does the phase of a sine wave refer to? Answer: The position
of a point in time on a waveform, measured in degrees.
◉ What is the significance of the 0-degree phase in a sine wave?
Answer: It represents the starting point at the baseline or the 0
amplitude level.
