Thanks Nich. What I was trying to say, but you managed to a lot more eloquently !
The 82dB figure was taken from a Dutch breakdown of the EU regulations applicable.
I assumed, maybe wrongly, that EU regulations also applied to the UK in the matter, at least for the next few hours (/days/weeks/months/years) !
Sorry if I inadvertently offended some folk; obviously unintentional. Only trying to help !
