Sound Level meter requirements

[John Pavlick]

Thanks everyone. I got a Rad Shack meter for now but I'm going to keep my
eyes open for an ANSI compliant one. I just missed a sale at MCM Electronics
so I'll have to wait. The tolerance of the RS meter (+/- 2dB) is not as
tight as some of the more expensive ones (+/- 1.5 dB) but for my purposes it
should be OK for now. I just want to see what I can do to improve noise
levels of some of my planes and also to compare them with other noise
sources. As long as I use the same meter, the qualitative results should be
meaningful even if the quantitative results are not extremely accurate.


 Lance - Thanks for the heads up re- the "court of law". I guess it would be
worth the extra money to buy a meter with the certificate of compliance
(most have an additional charge for this) if you intended to use the
readings to settle any disputes with neighbors (flying field complaints).
