The noise sources identified and their estimated sound power levels (L WA) are presented in Table 4.2.
Operational hours are proposed as presented in Section 1.1.

Modelled traffic movement data is based on hourly generation profiles provided by Pekol Traffic and
Transport (PTT). Table 4.3 provides the modelled movements within a 1 hour period for daytime,
evening and night. These movements are based on the peak hour traffic generation provided by
PTT.

4.1 Predicted Noise Levels

Noise levels (LAeq and LAmax) from the proposed development were predicted at existing sensitive
receivers. Predictions were made as follows:

                Vehicle and mechanical plant LAeq as presented in Table 4.4 with no barriers.
                Vehicle and mechanical plant LAeq as presented in Table 4.5 with no evening deliveries.
                Vehicle LAmax as presented in Table 4.6 with no evening deliveries.
