Point Source Sound

Point Source Sound - Objective

The purpose of this objective is: to have the amplified sound emanate from only one direction in the Classroom.

Point Source Sound - Benefits

	No Direct Sound Interference Patterns are generated by a Point Source Sound. (No Comb Filtering)
	No Interference Patterns is synonymous with High Clarity and Intelligibility Audio.

Two and Four Speaker Systems - Generate Interference Patterns

	Two or four speakers generate interference patterns which significantly degrades the audio clarity and intelligibility in the classroom.
	The laws of physics clearly show why one speaker delivers the best Audio Clarity and Intelligibility.
