Just to be perfectly Clear - I am not disputing that normal human hearing range of a healthy individual ears is usually in-between 20Hz and 20kHz.
My take away from the info/ reports/articles, by various different sources
(there are several more) is that research has shown that in environments where Humans live the total frequency range at which soundwaves travel safe enough to have an affect on the Human condition is at the 15Hz - 150kHz.
Millercarbon is absolutely correct that at this level this would be at an unconscious condition at best. So the argument then becomes - if this is true should it even be considered sound?
I have been convinced that it does. For the most basic fundamental reason that researchers know that frequency at this level has a direct affect on the part Human brain that is specifically responsible for emotion.
Even in the unconscious condition.
What is music if not the greatest Human emotional expression.
What I also find interesting is the manufactures who embrace the science and incorporate it in their products - even if I can't afford it....
