What is a sound system?
a functional arrangement of electronic components that is designed to amplify and distribute sound
What is the Conceptual Model of a sound system?
- acoustical energy 2. acoustical to electricity conversion 3. electrical manipulation 4. electrical to acoustic energy conversion 5. acoustical energy
What is the Practical model of a sound system?
What are examples of sound proccessing?
gain/volume
relative balance
tonality
artistic effects
dynamic control
creating multiple mixes
What is frequency?
the rate of air pressure fluctuation
What is a period?
amount of time required for one complete cycle of a sound wave
What is phase?
the relative time relationship of a sound wave to a known time reference
What is the equation for finding a period of a wavelenght?
P=1/frequency
How do you find the wavelength?
wavelenght= speed of sound(1130)/ frequency
Define frequency response
describes the relationship between the devices input and output with regard to signal frequency and amplitude
Define an octave
special musical interval between two tones, formed when the ratio between the frequencies of the tones is 2:1
What are the 31 band 1/3 octive frequencies?
20 25 31.5 40 50 63 80 100 125 160
200 250 315 400 500 630 800 1000 1250 1600
2000 2500 3150 4000 5000 6300 8000 1000 12500 16000 20000
What is Electricity?
behavior of charges
What is Current(I)?
organized flow of electrons
What is voltage?
the potiential difference between two points
