AMBIENT NOISE LEVEL MEASUREMENTS – 2019

On Wednesday 13th November 2019 ambient noise levels were obtained from adjacent to Block 3, the
closest residential to the Facilities Building. The results of these ambient noise level measurements are
detailed in Table 1 below.

The above ambient noise levels are lower than what would be expected for the density of residential
apartments in this complex. At the time of these ambient noise assessments very few (four) apartments
appeared to be occupied (gauged by whether at approximately 2120 hour or not there were any lights
on in the apartment at approximately 2120 hours) – three in Block 2, one in Block 3 and none in Block 4.
Some Blocks were still under construction. At this time it was anticipated that the ambient noise levels
were likely to increase, including the background sound level (LA90,T) once all of the apartments were
constructed and occupied.

It is anticipated that, with all of the apartments occupied, the background sound levels will be:

     •    daytime:                         45 dB(A);
     •    evening:                         40 dB(A).

In December 2019 (Monday 2 and Wednesday 18) evening background sound levels were obtained.
The early evening background sound level was 40 dB(A) LA90,T and the late evening background sound
level was 38 dB(A) LA90,T respectively, and these results support the above evening background sound
level of 40 dB(A).
