It would be very helpful if someone could post some info regarding the way decibels are recorded to test the amount of noise a car exhaust makes in the UK.
What i am interested to know is the methodology?
For example in Japan you have to hold the sound meter 50cm away from the back box at an angle of 45 degrees.
And legal limit seems to be 96 dbs over there.
Many thanks.
