While at Stretton I took the opportunity to use their sound monitoring equipment. Results from the 6 CKS running was that the loudest at 10 metre distance, with the background of a solid structure (ie no sound dissipation) was 37 dB.
Thought this might be useful. That one had an open ended exhaust , as the muffler had fallen off.
