Looks like the Tenma Compact model Robb links to
http://www.mcmelectronics.com/product/TENMA-/72-935 measures down to
40 dB (A-weighting only) for $30. I see there are a number of Tenma
and B&K meters that go as low as 30 dB for under $200. 30dB is about
the same as a good, commercial sound recording studio and quite a bit
higher than outdoor levels in remote areas.
Does the meter's use of A-weighting present a problem for the
low-noise mics/recorder extrapolation method--with no matching
weighting in the recorder? Rob D.
