The results of the noise level in November 2009 measurements show relatively lower noiselevel than July measurements. Although, in some of the locations noise level exceeded Bangladeshstandards and they are RS2, RS3, RS5, SA1, both ferry ghats, and end of approach road at N8 inJanjira. RS2, RS3, and RS5 are all located close to the district roads and traffic is the main contributorof noise, SA1 is located beside the Dhaka-Mawa highway, and ferry ghats are always noisy due to theloading unloading of vehicles in the ferries.Table 3-29: Noise Quality in the <strong>Project</strong> Area in November 2009.Location Date TimeMea Med Max Min Std L 10 L 90 L 50 L eqdBA dBA dBA dBA dBA dBA dBA dBA dBAJashaldia10:19 - 10:35 60.8 62.4 72.0 43.8 8.2 46.5 70.8 60.4 66.0Village13/11/2009(AQM-3) RS220:00 - 20:15 49.0 48.1 58.8 45.6 3.4 45.9 51.6 47.7 50.9Shamespur 16:55 - 17:11 60.7 60.5 73.1 51.5 6.2 53.2 69.5 59.7 65.113/11/2009(AQM-1) SA121:06 - 21:21 56.2 54.6 74.2 46.7 8.7 47.2 67.8 54.4 64.6Mawa Ferry15:20-15:35 72.7 74.1 81.1 ( 61.5 7.5 62.5 82.2 72.2 77.6a)Ghat13/11/2009(AQM - 2)20:20-20:35 69.3 68.3 84.8 ( 56.0 8.6 58.1 80.0 68.2 76.5MawaRoundaboutKumarbhog(RS3)13/11/2009a)16:25-16:40 67.4 65.7 82 (a) 58.8 6.9 60.1 75.7 65.4 73.020:42-20:57 66.5 65.6 74.4 60.3 4.9 60.5 73.9 65.0 69.117:21 -17:36 62.3 62.1 80.8 44.6 13.3 46.0 79.2 58.2 73.813/11/200919:30 -19:45 57.0 56.3 76.4 46.0 9.3 46.6 68.6 54.6 66.2Jabbar Fakir 15/11/2009 16:00-16:15 44.3 42.8 60.8 41.5 4.9 46.6 68.6 54.5 66.23-54
