Indicative background noise level at 59 North Pde (Court House) and TAFE NSW from operator attended ambient noise survey on Mount Street (refer to Figure 1 for site diagram).Note 2. External noise level at the Court House as described in Section 4.2.Note 3. External noise level based on a 20 dBA reduction for typical building construction with no special acoustic treatment assuming windows are closed. This assumption is based on the relatively highroad traffic noise levels in the area.Heggies Pty LtdA member of SLR Group
