EPA Noise Guidelines

QUOTE
it was recorded on a phone, so i doubt it is accurate. but then 116db was as loud as the phone could register, and i was only at idle.
To make an accurate sound level measurement, a sound level meter must be a "type 1" or, for an indication only, at least a "type 2" meter can be used. In the Acoustic Measurement trade, the dB meter in a mobile phone is known as "a fu.ken waste of time", and you would be more accurate to pick a number between 20 and 200 out of your mates butt.
So your doubt is very well founded.
For the correct testing procedure see
http://www.legislation.nsw.gov.au/viewtop/inforce/ subordleg+537+2000+sch.2+0+N
Both these sites are NSW, but the regulations are very similar in each state, and will all become identical in the very near future.
