CSD 303 Exam 1 || With complete solutions.
objective measurements of speech are part of what 3 things? correct answers diagnosis
assessment
intervention
what is a sound wave? correct answers traveling pressure fluctuation
(T/F): sound propagates through waves correct answers true
(T/F): in regards to air through which a sound wave passes, the air particles move correct answers false: the pressure fluctuation moves, not the air particles (particles just vibrate)
simple periodic waves (sine waves) are defined as: correct answers periodic oscillations of constant amplitude
duration of one cycle correct answers period (T)
f= ? correct answers f= 1/T
what is frequency correlated with? correct answers pitch
what is amplitude correlated with? correct answers loudness
(T/F): our ear detect phase shifts of waves in isolation correct answers false: we can only detect it in complex waves or when waves combine
aperiodic sounds correct answers sounds that do no shave a regularly repeating pattern (ex: fricatives)
white noise correct answers a random pressure fluctuation
transients correct answers sudden pressure fluctuations that are not sustained or repeated
low pass filter correct answers blocks out higher frequency components of a wave
high pass filter correct answers blocks the lower frequency components of a wave
band pass filter correct answers band stop filter correct answers center frequency correct answers bandwidth correct answers 1/2 total area of the filter
filter slope correct answers resonant frequency/ natural frequency correct answers the frequency an object prefers to vibrate at. no matter the input you will get this output
