Noise measuring and devices

[Gray E Fowler]

All I can say is that the $75 Radio Shack digital meter is ballpark only. 
It is calibrated to +/- 3dB! I double checked the one I bought for my club 
against an identical one owned by someone else and they were alway 1-2 dB 
different. Earl haury and Mike Harrison showed me their models that were 
$220 and +/- 1dB but I cannot remember the make/model. Both of theirs 
registered exactly the same when we were testing at a Texas contest. In 
short do not get the Radio Shack and depend on it.

Now flying masters and knowing that they measure sound at the Nats, I'd 
like
to start getting prepared.  Is there a decent, not too expensive noise
measuring device available?  Any ideas on this or the preferred method for
performing the actual measurent would be greatly appreciated.  I'm 
thinking
that the asphault method is most available to me.

TIA
