Hello, new poster,

I am trying to do a fairly simple, but non-standard, environmental noise model run for a shooting range.

The standard against which noise from the shooting range is to be compared is the Shot Noise Level (SNL). SNL is defined as the logarithmic average of the 25 highest LAeq(Fast) shot levels over a 30 minute measurement period.

Unfortunately, the modelling software only models for LAeq and LAmax.

Given that, in the model, all shot sound levels at the receptor locations would be at the same level, would the LAmax be equivalent to the SNL?
I believe that they are, but I just want to make sure I am not missing anything.

F, I am not familiar with these processes.
