  2. 2. OmnidirectionalOmnidirectional hears equally well from all directions. UnidirectionalUnidirectional favors sounds in front of it. They have a heart-shaped pickup pattern, hence the term cardioidcardioid. HypercardioidHypercardioid have a narrow, longer reach. They also hear sounds coming from behind.

  3. 3. How Microphones AreHow Microphones Are MadeMade:: DynamicDynamic MicrophonesMicrophones • the most rugged • can withstand rough handling and extreme temperatures • extremely loud sounds won’t damage it or distort the sound too much • best option for field interviews
  4. 4. How Microphones AreHow Microphones Are MadeMade:: CondenserCondenser MicrophonesMicrophones • more sensitive to physical shock and temperature • produce higher-quality sounds • prominent in music recording • need a power supply
  5. 5. How Microphones AreHow Microphones Are MadeMade:: RibbonRibbon MicrophonesMicrophones • ideal for recording voice-over narration, piano, and a variety of brass, woodwind, and string instruments • critical music pickup for television • normally used for recording acoustic string instruments • too sensitive for normal video work
  6. 6. • usually clipped to clothing • very small and rugged • used principally for voice pickup • can be the size of a fingernail • can be taped to musical instruments • indispensable in video production UsingUsing aa Lavalier “Lav”Lavalier “Lav” MicrophoneMicrophone
  7. 7. UsingUsing aa Hand “Handheld”Hand “Handheld” MicrophoneMicrophone • are handled by the talent • used to have some extra control over the sound pickup • a reporter can move a hand microphone closer to his or her mouth and can also point it toward the person he or she is interviewing • a singer can control the intimacy or emphasize the richness of the sound (its presence) of his/her voice
  8. 8. UsingUsing aa BoomBoom MicrophoneMicrophone • Usually a hypercardioid mic • pick up sounds from fairly great distances • Makes sounds to seem to come from close by • Eliminate or reduce all sounds that lie outside its narrow pickup pattern.
