Sound Envelopes
Sound Envelopes
(OP)
While the ideal loudspeaker emits a sphere of sound, many people picture the typical loudspeaker as emitting a cone of sound. But, I am trying to model outdoor mass notification systems, such as tornado warning systems. These look like a stack of pancakes on a pole and can emit 360 degrees in the horizontal plane* of the speakerstack...if not almost spherically around the speaker stack. So, before I press the vendor for more details, any clue what the sound envelope might look like for such a design?
*I know, a plane has no thickness while the speaker-stack does. But, the vendors claim 360-degree coverage...which may be emblished if they're trying to say constant dB-SPL at 360o.
Thanks in advance to all - for your thoughts on this.

A speaker placed with its back down and projecting upwards against the outside of a horn would be capable of covering 360º uniformly. The faint picture in http://w
