Also, I doubt any safe levels have been determined, since these things are usually measured and defined by scientists, who don't believe we can hear those tones.

Of course, I proved myself wrong shortly after writing this. OSHA has done some work on this: http://www.osha.gov/dts/osta/otm/noise/h...onics.html
At 20KHz, the 8hr time-weighted average is 92db, which means that over eight hours, you should have an average db of less than this value. Considering that a normal conversation occurs around 65db, my unprofessional, uneducated, and generally ignorant recommendation is to keep the levels down around that level.
Sean, thanks for the concern and the information provided by he link you posted. I want to make sure that I hear the subs in the safest way possible because your ear is the gateway to your mind if you are going to use subs to change yourself, hence the precaution.
I still want to know what you discover with your db meter, man!
Well, Sean, these are the search results link if you are interested in apps on google. You can turn your iphone into SPL meter with this.
