Review on Enhance Your Sound Measurement Accuracy with the Extech 407736 Range Sound Lever by John Mejia

Generally satisfied with the meter BUT criticized by CalTrans / Sound Engineering Company for the meter being unable to record Leq readings for a period of time. Leq is the average over 5 or 30 minutes, etc. This non-Leq meter will only show instantaneous values of interest, but the average is important when measuring road noise levels. Overtaking trucks/motorcycles etc. is a problem without LEQ ability. I had to buy another Leq meter before my readings were taken into account. Otherwise it's a great meter.
