Term
|
Definition
| (aka resistance mics) oldest/diaphragm is mounted in a "cup" which contains carbon granules/electrical current is passed through these granules to be compressed and released |
|
|
Term
| Crystal/Ceramic Microphones |
|
Definition
| operate off of the "Piezoelectric effect" which means to press/ the electrical voltage will be created when the piezoelectric material is subjected to mechanical stress/ commonly used in acoustic guitar pickups |
|
|
Term
| Dynamic/Magnetic Microphones |
|
Definition
| also called electrodynamic and electromagnetic mics/ discovered by Michael Faraday/ the diaphragm are typically dome shaped/ most common |
|
|
Term
|
Definition
| has a transducer similar to a dynamic microphone/also operates under Faraday's Law/ has a flat thin strip of metal/ delicate mics |
|
|
Term
|
Definition
| also called capacitor/ developed by Bell Labs by E.C Wente but mass produced by Georg Neumann/ operates with 2 metal plates that are parallel with each plate holding an opposing charge/ require a preamp/ diaphragm constructed by thin metal or thing plastic coated with gold/nickel |

Definition
| e=Blv ... e = electro magnetic force (in volts) / B = magnetic field strength/ l = the length of the conductor/ v = the velocity of the conductor moving through the magnetic field |
|
|
Term
| Faraday's Law states that... |
|
Definition
| moving a conductor (coil of wire) through a magnetic field will cause a voltage to be induced across the conductor. |
|
|
Term
|
Definition
| A plot that describes the sensitivity of a microphone to sounds arriving from any direction over a 360 degree range. |
|

Term
|
Definition
| sounds that arrive at 0 degrees position relative to the microphone |
|
|
Term
|
Definition

Term
|
Definition
| Omni-Directional and Bi-Directional |
|
|
Term
|
Definition

|
|
Term
|
Definition
| sensitive to sounds coming from the front and rear... natural pattern for PRESSURE GRADIENT microphone capsules |
|
|
Term
|
Definition
| as the distance from the source decreases, microphones with directional polar patterns will exhibit an increase in low frequency response... as you move the mic further away from the source, certain frequencies (usually low end) will increase |
|
|
Term
|
Definition
| little notches that are designed in the microphone to help keep unwanted frequencies out |
|
|
Term
| Omnidirectional (pertaining to proximity effect) |
|
Definition
| has extended low frequency pickup (less proximity effect than directional microphones) |
|
|
Term
| Bidirectional (pertaining to the proximity effect) |
|
Definition
| usually very even except at highest frequencies/ more proximity effect than cardioid or hyper-cardioid |
|
|
Term
