ASLP 3030- Speech and Hearing Science
EXAM 1 Review | Already Passed
Attack - ✔✔~also called "Rise"
~time from silence to maximum amplitude
Release - ✔✔~also called "Fall"
~time from maximum amplitude to silence
Compression - ✔✔
Rarefaction - ✔✔decrease in molecule density
Frequency - ✔✔number of cycles completed per second
Amplitude - ✔✔displacement from equilibrium position
Phase - ✔✔~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) - ✔✔time it takes to complete one cycle
P = 1/f
Wavelength - ✔✔physical length of a single cycle
wavelength = speed of sound (c)/ frequency (f)
Peak Amplitude - ✔✔maximum displacement of the waveform from the
baseline
Peak-to-Peak Amplitude - ✔✔difference in displacement between the
largest amplitude above the baseline and largest amplitude below baseline
Envelope - ✔✔pattern of change in amplitude
Damping - ✔✔reduction of the amplitude of a sound or sound pressure
Frequency Modulation - ✔✔the frequency of the wave is varied
Amplitude Modulation - ✔✔the amplitude of the wave is varied
Beats - ✔✔~when two sinusoids with slightly different frequencies are
presented simultaneously, a "beating stimulus" is created
~perceives as a tone with loudness that beats
