Speaker Characteristics






-- required to realize: 

High Clarity & Intelligibility Classroom Audio

  1. The speaker must be a Wide Dispersion Speaker.
    Flashlight versus Light Bulb Speaker Analogy

  2. The amplified sound should emanate from 
    a Point Source Sound.

  3. For the best Clarity & Intelligibility the amplified sound
    should emanate from the same direction as the teacher's voice

  4. The speaker must be a Flush Wall or Ceiling Mount Speaker.

  5. The speaker should be driven by an amplifier with 
    a dedicated equalizer 
    to ensure an optimal frequency response.

Reverberation Time & Signal-to-Noise Ratio
- also affect the Speech Clarity & Intelligibility


Only One Speaker has to be Installed as opposed to Two or Four Speakers.
This aspect significantly reduces your installation time and costs. 

Stylish Unobtrusive Installation
