Objective Sound - CORRECT ANSWER Sound that is physical and can be measured
Compression - CORRECT ANSWER an area of greater than normal barometric pressure
Rarefacetion - CORRECT ANSWER an area of less than normal barometric pressure
Cycle - CORRECT ANSWER A completion of compression and rarefaction
What are the 7 characteristics of waveform? - CORRECT ANSWER Wavelength, amplitude,
velocity, envelope, frequency, phase, harmonic content
Masking - CORRECT ANSWER The manner in which a loud sound covers up a quieter sound
Diffraction - CORRECT ANSWER The bending of a wave as it moves around an obstacle or
passes through a narrow opening
What determines if or how a wavelength will diffract around an object? - CORRECT
ANSWER Wavelength
4 parts of envelope - CORRECT ANSWER Attack, Decay, Sustain, Release

What is amplitude? - CORRECT ANSWER how much of something
, Peak-to-Peak - CORRECT ANSWER The measurement between the maximum positive and
negative of a wave
Peak amplitude - CORRECT ANSWER the measurement from centerline to the maximum
positive or negative of a wave
RMS (root mean square) - CORRECT ANSWER The average amplitude of a wave over a given
time period
