          to achieve compliance

Noise impacts to receiver 2 from amplified entertainment inside the hotel are predicted to
comply with the assessment criteria after 10pm. This is assuming all external windows and doors
closed and a 22dB reduction from inside the hotel to outside is achieved.

Predicted noise impacts to receiver 2 from amplified entertainment on the hotel terrace are
predicted to exceed the assessment criteria after 10pm. To achieve compliance, the noise source
level at 3m should be no higher than 92 dB(C).
