                      Tuesday 28th Nov 2017               Measurement started
                      Wednesday 29th Nov 2017             63.4 dB(A)                               33.8 dB(A)
                      Thursday 30th Nov 2017              63.9 dB(A)                               38.8 dB(A)
                      Friday 1st Dec 2017                 Measurement ceased
                      Average                             63.7 dB(A)

                     The internal noise criteria are presented as LAeq(1 hour) levels, therefore the
                     difference between the LA10(18 hour) and the LAeq(1 hour) noise levels measured
                     during the daytime/evening and night time periods are applied to predicted LA10(18
                     hour) noise levels. The measured weekday highest LAeq(1 hour) noise levels and their
                     respective differences to the LA10(18 hour) are provided in Table 4.

                      Average                   66.6                                        +3.4

                     Table 4 shows that for this site:
                                                LAeq(1 hour), Day = LA10(18 hour) +3.4 dB


                     Background noise levels have previously been carried out by RoadPro Acoustics
                     at the Site at the location shown in Figure 5, with results shown in Table 5 and
                     Table 6.
