19.
What is the frequency of a tone that has a period of 50 ms?
incorrect
20.
relationship pf amplitude/compression and intensity.
A.
-don’t conduct sound well
B.
=1/500 sec =0.002 sec =2ms
C.
-Frequency (# of cycles, pitch) -- measured in Hertz (Hz) -Intensity (height of wave, amplitude) -- measured in decibels (dB) -Duration -- measured in milliseconds (ms)
D.
A single tone with increased amplitude
E.
-The number of complete cycles occurring during one second. -The more cycles that occur in 1 sec the higher the frequency and vice versa.
F.
Something with elastic properties must be put into motion
G.
=1/1000 sec =0.001 sec =1 ms
H.
-Repetition -each cycle must occur and reoccur at the same rate
I.
1. Something put into vibration 2. Something to conduct (i.e., carry or transmit) the sound vibrations
J.
Pitch
K.
valley that's the point of maximum rarefaction
L.
The greater the compression/amplitudue, the greater the intensity.
M.
-The length of time it takes for a tone to complete one cycle of vibration
N.
cancellation
O.
1. Neural Signals 2.Muscular Contractions 3. Structural Movement(lips, jaw, tongue, velum, vocal folds) 4. Areodynamic Events (result of structural movement- friction sounds, building up & releasing of pressure) 5.Acoustic Consequences 6.Speech
P.
-the tendency for an object to return to its normal resting state.
Q.
decimal moves left 3 times = 0.050 sec = 1/0.05 = 20 Hz
R.
-A sound wave that is non-repetitive, has a different rate for each cycle -No specific frequency can be assigned to -it has no perceptible pitch -it is random noise
S.
-the tendency for a body at rest to remain at rest, or a body in motion to remain in motion.
T.
Loudness
