Microphone


Definition:

  • (n.) An instrument for intensifying and making audible very feeble sounds. It produces its effects by the changes of intensity in an electric current, occasioned by the variations in the contact resistance of conducting bodies, especially of imperfect conductors, under the action of acoustic vibrations.

Example Sentences:

  • (1) "I pulled the microphone in front of my seat, not a knife.
  • (2) I’ve warned Dave before to mind his ps and qs when the cameras are rolling, but the problem is you can never tell when the microphones are switched on.
  • (3) The effects of auditory fatigue, using a temporary threshold shift (TTS) paradigm, on cochlear microphonics (CM) and on auditory brainstem-evoked potentials (ABEP), were studied in normal-hearing subjects during the development of permanent threshold shift (PTS).
  • (4) The microphonic potentials of liverdamage animals was lower about 3.4 dB than potentials of healthy animals.
  • (5) It consisted of a conventional precordial or esophageal probe connected to a microphone by a rubber adapter.
