Question 3

Hearing Range

Answer 3

20 Hz to 20 kHz

Question 4

Sine Wave

Answer 4

Basic wave with smooth rise and fall of the crest

Question 5

Crest

Answer 5

Top of the wave form
(Compression portion of the wave)

Question 6

Cycle

Answer 6

When a source has completed one crest and one trough

Question 7

Wavelength

Answer 7

Distance between waves

Question 8

Frequency

Answer 8

The number of times the wave occurs in one second.
Measured in Kilohertz,

Question 9

Amplitude

Answer 9

Strength or intensity of a sound pressure wave “Height” of wave.

Question 10

Phase

Answer 10

The way multiple sound waves interact in an acoustical or electrical space

Question 11

How Phase interacts:

Answer 11

In phase - the waves add together
Inverse - they cancel each other out
Different waves -
Make a new wave

Question 12

Speaker cable

Answer 12

Made of two identical wires

Question 13

Line level cable

Answer 13

Instrument cable;
Two conductor design, surrounded by a braided wire shield.

Question 14

Microphone cable

Answer 14

Three conductor design

Question 15

Impedance

Answer 15

The resistance to the flow of an electrical current
High impedance is a guitar cable; less wires
Low impedance is a microphone cable, more wires.

Question 16

Balanced/unbalanced

Answer 16

Instrument cables; unbalanced
Microphone and Speaker cables: balanced

Question 17

XLR / Microphone cable sonic properties

Answer 17

The hot and cold wires take the sound and it becomes inversed, cancelling out all the noise (including picked up noise.)
Then it gets to the end and is flipped back so the sound comes out all nice and clean.
