Besides having a Full Range Spectrum of White Noise, which is not too difficult to obtain.
Where in this World would you get a Full Spectrum Transducer to Faithfully Reproduce it sound?
Even the BEST Conventional Speaker with its Very Limited Frequency Response has Hundreds of "Dips and Peaks" in the output.
(This is Just Between 20 to 20,000 Hz)
Never mind Trying to get into the Ultra Sonic Region with a Full Range transducer. That is Extremely DIFFICULT.[/quote]
I guess you just take what part of white noise that fits between 20 to 20,000 Hz. Most public performances don't include producing sonic pain fields for the entertainment of the audience (although there are always exceptions) or inducing a chorus of howls from the neighborhood dogs.
