Fletty's new shed WIP ....or is it a retrospective??

I am sure you all know that the Db scale is exponential, but it is worth remembering.

The distance at which measurements are taken is very important and some noise of the same magnitude but different pitch can have varying results on the human ear. I would suggest that a DC would be nowhere as annoying as a router being given some curry and the router not as annoying as one of the lunch box thicknessers, as PmcGee so mischievously refers to the bench top variety.

I read just now that a reduction of 10db to the human ear sounds about half as noisy.

At one time racing cars had completely unrestricted exhausts, but the noise was initially restricted to 110db, which is still uncomfortably loud. I am not sure of the requirements today. Chainsaws are around 90db.

At work we have plenty of noise. Sometimes if we get a steam leak we have to wear both ear plugs and ear muffs if we are required in the vicinity of the leak. You could offer that to neighbours to cope with the issue, but as the legal people among you will point out, that is tantamount to admitting that there is a problem. Prima facie evidence!

Ian makes a good point about the timing of the noise and Chris Parks is right on with noise levels in keeping with the surroundings. I am with Sawdustmaker with those blower vacuum thingys. Very annoying sound.

The best solution is to have woodworking neighbours .

Recently during a house reno next door a plumber fired up his concrete cutter. Myself and some tradies working at my place wore ear defenders the whole time it was working due to the exhaust being so loud. I am used to being around angry two strokes at race tracks but this thing was in another category altogether. On a building site it might have been annoying, in our quite neighbourhood it was intrusive in the extreme meaning of the word. The lack of standards to take measurements of this nature make it meaningless to compare readings IMHO and I always regard readings taken with phone apps as fairly useless having seen how more than has been wildly inaccurate.
