Term
| A plot that describes the sensitivity of a microphone to sounds arriving from any direction over a 360 o range |

|
|
Term
| Equal sensitivity to sounds from ALL directions. This is the natural pattern for pressure capsules. Has less proximity effect than directional mics and extended low frequency pick-up. |

Term
| Sensitive to sounds arriving from the front and the rear. |
|
Definition
|
|
Term
| Most sensitive to sounds arriving from the front while rejecting sounds from rear |
|

|
|
Term
| Sensitive in a slightly narrower pattern in the front than a Cardioid and has a small lobe at rear |

|
Term
| Sensitive in a narrower pattern in the front than a Cardioid and has a prominent lobe at rear |
|
Definition
|
|
Term
| Extremely narrow area of sensitivity in front with extended “reach” also has multiple lobes which vary in position with frequency. mic polar pattern is not made from combining pure patterns, but is created by using an interference tube |

|
Term
| In a moving-coil microphone, sound waves cause movement of a thin metallic diaphragm and an attached coil of wire that is located inside a permanent magnet. |
|
Definition
|
|
Term
| microphone where transducer is a strip of extremely thin aluminum foil, wide enough and light enough to be vibrated directly by the moving molecules of air of the sound wave, so no separate diaphragm is necessary |
|
Definition
|
|
Term
| has two electrically charged plates—one that can move, which acts as a diaphragm, and one that is fixed, called a back- plate. This is, in effect, a capacitor with a positively and negatively charged electrode and an air space in between |
