8.2      Assessment for car park noise


         Using the source data from Table 7, the noise emissions at the existing residential properties have
         been calculated and presented in Table 8. Calculations have considered:


                    Worst case noise emissions from car park would be 65dBA LAmax at 10m, typical of a car

                    door closing;


                .   Worst case locations for various vehicle manoeuvres within the car park;


                .   Distance attenuation; and


                .   Adjustment of +2dBA for annoying characteristics (i.e. tonality, impulsiveness) that are
                    just detectable, and +5dBA for annoying characteristics that are prominent / clearly
                    audible.

        It can be seen in Table 8 that the noise due to usage of the proposed car park for the commercial

        development complies with the daytime, evening and night limits for residential areas adjoining
        the site.
