Sound

Question 1

Crest

Answer 1

Maximum Pressure, Top Curve

Question 2

Trough

Answer 2

Release, Bottom Curve

Question 3

Frequency

Answer 3

The number of cycles that the sound wave travels in 1 second.

Question 4

Wavelength

Answer 4

The measurement of one cycle of a wave. (crest to crest or trough to trough)

Question 5

How do you find wavelength?

Answer 5

wavelength = velocity(speed of sound) / frequency

Question 6

Pitch

Answer 6

How high or low the sound it (determined by frequency)

Question 7

Amplitude

Answer 7

Measure of the air compression of sound.

Question 8

Attenuate

Answer 8

Get weaker (sound waves attenuate with distance)

Question 9

Transduction

Answer 9

Conversion of one form of energy into another (microphone)

Question 10

Impedance

Answer 10

The inherent opposition to the flow of the electrical current.

Question 11

Omnidirectional Microphone

Answer 11

Has sound sensitivity all around the microphone except for right behind it. (ambiance, one speaker close to the mic)

Question 12

Bidirectional Microphone

Answer 12

Sound sensitive in two directions (two sources or speakers)

Question 13

Unidirectional Microphone

Answer 13

Sensitive in one direction (cardioid) still has minor side and back sensitivity.

Question 14

Lavalieres

Answer 14

Clip on microphone.

Question 15

Shotgun Microphone

Answer 15

Used to capture sound from far away (on set or in the wild)

Question 16

Analog Recording

Answer 16

Direct relationship between the sound waves and the recorded signal resulting in the recording of a continuous wave. (potential unwanted noise)

Question 17

Digital Recording

Answer 17

Waves are measured or sampled and the information is quantized, recreating the signal (clearer sound).

Question 18

Bit Depth

Answer 18

How many pieces of information are measured for each sample. (the more the wave is sampled the better the sound is)

Question 19

Sampling Rate

Answer 19

The amount of samples taken each second (44.1-48 kHZ)

Question 20

Foley

Answer 20

Sound that is more tailored to a specific image (recorded in post production)

Question 21

Automatic Dialogue Replacement (ADR)

Answer 21

Actors record their dialogue over in post-production.

Question 22

Synchronous Sound

Answer 22

Sound that matches the action and is recorded at the same time as the picture.

Question 23

Nonsynchronous sound

Answer 23

Any sound not recorded with the image and does not match the action (background noise, conversations, dishes)

Question 24

Diagetic Sound

Answer 24

Part of the story, characters are aware of it (dialogue, piano player, footsteps)

Question 25

Nondiagetic Sound

Answer 25

Sound apart from the story, characters cannot hear it (narration, soundtrack)
