H2-33: SPEAKER AND EXPONENTIAL HORN

Additional Info

  • ID Code: H2-33
  • Purpose: Demonstrate the effect of an exponential horn enclosure.
  • Description: A small loudspeaker is held up behind the opening of an exponential horn. The sound becomes much louder, especially in the bass. A horn enclosure has the effect of taking an extended source such as a loudspeaker and creating the best impedance match with the outside world, providing the most coherent plane wave. Compare this to H2-32, which uses the same speaker with a flat baffle. Invite students to speculate about what the effects the different shapes have.
