  4.      EXISTING NOISE ENVIRONMENT

  In order to assess the severity of a possible environmental                    noise problem it is necessary to measure

  the ambient       background       noise level at the times and locations            of worst possible annoyance.   The

  lower the background            noise level, the more perceptible          the intrusive    noise becomes and the more

  potentially annoying.

  A background        noise survey was conducted              between Saturday 23«1 April 2016 and Friday 29th April

  2016. The background             measurement        location (BG MLJ)          was located behind the existing   church

  building (see Figure 4.1). The measured levels are considered                     free field.




   Ambient      sound pressure        levels were measured            genemlly    in accordance   with Austmlian   Standard
   ASI055.1: 1997 - 'Acoustics-Description                and measurement of environmental         noise - Part 1: Geneml
   procedures'. Ambient noise levels were recorded at continuous 15 minute intervals. (see Figures 4.2, and

   Tables 4.2)
