       Table 12: Predicted amplified entertainment noise emissions from the proposed development with
                                          windows and doors open.

     A level of 91 dB(C) measured at 3m from the speaker is predicted to comply with the adopted noise
     criterion when all external doors and windows are kept closed. When doors and windows are open a
     level of 71 dB(C) measured at 3m from the speaker is predicted to comply with the criterion. These
     are relatively low sound source levels, particularly the level of 71 dB(C), which is very low level
     background music levels.
