Wes:
As someone on the other lists specified, dBa and dBb are somewhat unreliable
in fulfilling our needs in the noise abatement issue. I think it was
mentioned that dBc is the closest match to "what we hear." I don't believe
the Radio Shack meters have the dBc filter (or is that a non-filter?). For
this event the "if it sounds loud" guideline is workable. FCSCC did use the
RS meter when we ran at Southern CT State University in the early nineties.
That was what I mentioned in the previous report.

Matt, our ruling is currently shown below.
14) All vehicles must be muffled, with a maximum sound-level of 90
dba at 100
feet. After one warning, disqualification may result.
If anyone has any questions let me know. I am submitting your
question to the
officers. If thier ruling changes, I would say stick to the level I
mentioned
above.
