Radio Shack sells one for $60, claims accuracy of 2 dB at 114 dB.
It's pretty hard to measure sound pressure level more accurately than
that outside of an anechoic chamber.


$49 and change in our neck of the woods. And yes, it is pretty accurate...
or at least reproducible. We use ours to measure the sound pressure of
salutes. The digital version has a sample-and-hold feature we need for peak
readings.
