truck there are, when i was doing my engineering qualifications there was all manner of ways of measuring sound, ranging from distance, frequency, footprint, effectiveness, how it effects humans etc etc. i dare say even 1 db at the right frequency could kill you.

When noise levels are quoted they should either be in dB or more commonly dB(A). A level in dB will always be louder than one in dB(A) of the same number.
Also the levels quoted are sometimes Sound power levels, which is at source, or sound pressure levels at a cetrtain distance.
If anyone needs advice on how to build a relatively cheap acoustic box to go around a genny that will still let enough air in to keep cool then contact me.
Damm- I may have just given the game away that I don't really work for the tax man!!

Well, just thought i would check in with a quick report on the Makro 42 quid job. It is definately not silent running and will require some kind of muffling system if you plan to run it continuosly. I plan to dig a pit and drop it in, then cover it over with a board with some exhaust holes. However on the plus side it turned over without any problems, unlike the 2 stroke attached to the mini moto which is a pain in the butt to start and it apppears to be able to power all the required gear.
I think the offer is on till the 10th so if you are quick, you might just make it.

Jay, see balck granny nee tax man, post. Cooling will be paramount especially in france in june. you may wish to use the excess heat to warm the swimming pool. could be a patent here somewhere. a device which keeps the genny quite but cool, chills the beer and warms the swimming at the same time. answers on a fag packet.

300 watts at 12 volts is 25 amps. The battery will last just over an hour. Very clever (and cheap) device, which will have its uses.
I liked the idea of digging a pit to silence the genny, but what happens when it rains? I know it won't but we had problems with the KKOC pissoire one year when it did.

My local Makro (Fareham)were out of the £42 (plus VAT) job today but they say they may be getting some more in (don't hold your breath).
They had a much bigger (and heavier) 4-stroke one for £129. Plenty of those in stock!
