Electret condenser microphones: They are used in many applications, from high-quality recording and lavalier use to built-in microphones in small sound recording devices and telephones. Though electret microphones were once low-cost and considered low quality, the best ones can now rival capacitor microphones in every respect and can even offer the long-term stability and ultra-flat response needed for a measuring microphone. Unlike other capacitor microphones, they require no polarizing voltage, but normally contain an integrated preamplifier which does require power (often incorrectly called polarizing power or bias). This preamp is frequently phantom powered in sound reinforcement and studio applications.

Dynamic microphones

Dynamic microphones work via electromagnetic induction. They are robust, relatively inexpensive and resistant to moisture, and for this reason they are widely used on-stage by singers. There are two basic types: the moving coil microphone and the ribbon mi ...more

THE DYNAMIC MIC:
Dynamic mics are useful when the sound source is close and reasonably loud
CAPACITOR MICS:
An audio chain is only as good as its weakest link, so there's little point in using a top-price capacitor mic with a cheap cassette multitracker
BACK-ELECTRET MICS:
I dont know much abt this
As fas as i know these are the types

Dynamic microphones
Ribbon microphones
Carbon microphones
Piezoelectric microphones
Laser microphones
Liquid microphones
MEMS microphones
Speakers as microphones

(at distances of a few centimeters) results in a bass boost. This is known as the proximity effect

microphones may be measured with different sound sources and distances, but there is no standard and therefore no way to compare data from different models unless the measurement technique is described.
