ASLP 3030- Speech and Hearing Science
EXAM 1 Review UPDATED ACTUAL Exam
Questions and CORRECT Answers
Attack - CORRECT ANSWER - ~also called "Rise"


~time from silence to maximum amplitude


Release - CORRECT ANSWER - ~also called "Fall"


~time from maximum amplitude to silence


Compression - CORRECT ANSWER -



Rarefaction - CORRECT ANSWER - decrease in molecule density



Frequency - CORRECT ANSWER - number of cycles completed per second



Amplitude - CORRECT ANSWER - displacement from equilibrium position



Phase - CORRECT ANSWER - ~position of the waveform in its cycle at a specific
moment in time


~refers to the particular point of a cycle


~expressed in degrees of angle

, Period (t) - CORRECT ANSWER - time it takes to complete one cycle


P = 1/f


Wavelength - CORRECT ANSWER - physical length of a single cycle


wavelength = speed of sound (c)/ frequency (f)


Peak Amplitude - CORRECT ANSWER - maximum displacement of the waveform from
the baseline


Peak-to-Peak Amplitude - CORRECT ANSWER - difference in displacement between the
largest amplitude above the baseline and largest amplitude below baseline


Envelope - CORRECT ANSWER - pattern of change in amplitude



Damping - CORRECT ANSWER - reduction of the amplitude of a sound or sound
pressure


Frequency Modulation - CORRECT ANSWER - the frequency of the wave is varied



Amplitude Modulation - CORRECT ANSWER - the amplitude of the wave is varied



Beats - CORRECT ANSWER - ~when two sinusoids with slightly different frequencies
are presented simultaneously, a "beating stimulus" is created


~perceives as a tone with loudness that beats


Beat Stimulus Frequency= (f1 + f2)/2
