Objectives Know the different types of microphones
and the context in which they are used in.

How they work
![Page 4: Objectives Know the different types of microphones and the context in which they are used in.](https://reader036.fdocuments.in/reader036/viewer/2022062305/56649e0f5503460f94afa861/html5/thumbnails/4.jpg)
Dynamic and CondenserDynamic Condenser
Paper diaphragm Gold leaf diaphragm
Robust mic – can occasionally be dropped without ill effects
Also known as capacitor microphones
Generally used for live performances
Because of gold leaf diaphragm, +48 volts is required to boost the signal.
Can cope with high sound pressure
This is known as phantom power.
Does not respond well above 16 kHz (dependant on make and model)
Better build quality so are more expensive.
Not so good at picking up sounds further away from mic.
Tend to be used for studio recording or ambient recording.

Other types of microphonesBlack-electric – Like condenser mics but
contains a battery to supply the +48V (they can also take the phantom power as well though)
Boundary – Used for capturing sound over a large area including the rebounding sound off walls. (omni directional)
Ribbon – Like a dynamic mic but amplified by a transformer designed for the mic.
Contact – Mics that need to be in direct contact with the sauce. Such as pickups used in guitars.

Polar patternsImportant to know which way to point the
microphone.Three main polar patterns – omnidirectional,
unidirectional (or cardioid) and figure of 8.

Omnidirectional

Unidirectional (cardioid)
