The short-term attended noise monitoring data reflects that across the proposal study
area there is a small variation between the daytime, evening and night-time
background average noise levels in the city centre. Night-time average noise levels
are not significantly less than daytime noise levels, generally differing by up to
3 dB(A). The results also show that the city centre is a noisy environment. Whilst
road traffic generated noise contributes most to the ambient conditions, other noise
sources such as human activity and air conditioning units also make a notable
contribution.
