The microphone is a ------- that changes the motion of acoustical energy into electrical energy |
transducer |
|
Air pressure compression is formed when |
air molecules are pushed together |
|
A graphic representation of the rarefactions and compression of a pure tone sound is called |
a sine wave |
|
The time it takes for a wave to make one complete cycle or a 360-degree rotation is called |
an interval |
|
The-----of a sine wave indicates the volume of the sound |
amplitude |
|
Generally humans can hear frequencies as high as |
20,000 HZ |
|
All sound is a combination of various waves. The most basic of combined waves is called |
Sine Wave |
|
The smallest sound level change that the human ear can hear is |
about 2 dB |
|
According to our book, the terms "pitch" and "frequency" essentially mean the same thing and may be used interchangeably (T/F) |
False |
|
Microphones change sound into electrical energy in different ways. The mic that responds to the difference in the pressure of the sound is called a __________ microphone. |
ribbon |
|
This mic picks up sound only from the front of the microphone than the sides and the back |
super-cardiod |
|
Directionality in microphone is usually attained as a result of sound wave cancellation. (T/F) |
True |
|
Microphones that exhibit a "Proximity effect" will tend to: |
tend to boost the bass (lower) frequencies |
|
In referring to the "range" of a microphone, usually the producer is referring to: |
the microphones frequency range |
|
Professional mics most susceptible to plosive sounds such as "B" an "P" sounds would probably b: |
a ribbon mic |
|
With regard to how microphones respond different to sound frequencies the aspects of frequency response that a producer would evaluate would be. |
the range of frequencies a microphone can pick up |
|
According to your book, an XLR connector is a filter used to reduce unwanted high frequencies in hand held microphones. (T/F) |
False |
