4 Environmental Analysis <br /> 4.13 Noise <br /> NSA-3, while the ambient noise level ranges from 39-45 dBA during the morning, 44-50 dBA <br /> during the afternoon, and 40-47 dBA during the night. With the Mitigation Measures NOISE-1 <br /> and NOISE-2, the Project would not increase the ambient noise level by more than 3 dB and <br /> results in a less than significant impact. <br /> Table 4.13-8.
