Reference
The standards behind your noise condition.
What each one is for, what it actually requires, and what makes an assessment fail.
A planning officer or an environmental health officer has put a standard number in a letter, and now you need to know what it means. These are the references we wanted when we started: what each standard is for, what it requires in practice, and where assessments come apart.
Each page is written by the engineer who applies the standard on site. The edition and amendment are stated in full, because the edition is the first thing an officer checks, and the thresholds are quoted as the standard states them rather than as a pass mark that does not exist.

Which one applies
Start from the condition, not the standard.
Assessing a scheme against the wrong method is the most expensive mistake on a noise report, because the survey has to be done again. This is the short route from what you have been asked for to the standard that governs it.
