Examples of amplifier in the following topics:

  • Volume

    • Speakers control the production of sound either using their own voice or a microphone so that amplified sound is loud enough to be heard.
    • Higher amplitudes on the wave graph are interpreted as a higher volume, hence the name "amplifier" for a device that increases amplitude.
    • The signal may then be sent to an amplifier.
    • The electronic amplifier increases the power of a signal.
    • A loudspeaker or headset receives the input to produce the amplified sound.
  • Technology

    • Amplified or not, at the beginning of the speech, the speaker should ask, "Can you hear me in the back?
  • Choosing the Right Visual Aid

    • Visual aids should support, clarify, and amplify, not repeat what you are saying.
  • Using Transitions

    • Remember that your head and face are your key expression amplifiers.
  • Articulation and Pronunciation

    • The first act of speech is breathing, in which you get air into a storage chamber; second is phonation, the process by which you force air into vibration by the action of the vocal folds; third, resonation, in which your mouth,nose and throat cavities amplify the sound so you can hear it; and finally there is articulation, in which you modify the sound by movement of the teeth, tongue, and lips into recognizable patterns.
