True Bill, but you need to put the expert in place yourselves, otherwise THEY will install one which is not what you want.
There are so many variables in sound measurement that you can really only get a mean average reading anyway, and the installed expert should take these variables into account when making his analyses.
I rather like the idea of the measurement of sound being taken at the perimeter fence, rather than trackside. The dragstrip here in Perth was built into a V in the ground, so that the sound travels upward, rather than cross-country.

Stock car tracks enjoy a similar benefit ( albeit on a smaller scale ) from the spectator embankments and usual 'wall' around the track.
