So, if all the active devices at the same time, the resonance noise source way 1.5 m was 98.21 dBA, the noise level 35 m source way resonance is 70.74 dBA. According to the standard QCVN 26:2010/BTNMT of the maximum limit allowed for the noise common area from 6 to 21 h is 70 dBA. So, the way resonance noise source 1, 5 m of the equipments in the construction process will exceed 1.5 fold times-standard, level 35 m of the source way resonance construction equipment during construction will exceed the standard fold 1.01 times will affect workers and residents around the area of the project (peace and condominium residences Sacomreal). At a distance of 40 m, 100 m, 200 m resonance noise of the construction equipment reached QCVN 26-2010 (6  18 h).

Thus, if all devices are operating simultaneously resonant noise source way is 98.21 dBA 1.5m, resonant noise from source 35 m is 70.74 dBA. NTR standard 26: 2010 / BTNMT maximum limits for noise allowed normal area from 6am to 21h is 70 dBA. So resonant noise level 1.5m from the source of construction equipment during construction will exceed 1.5 times the standard, resonant noise level from 35m sources of construction equipment during construction Construction will exceed 1.01 times higher standards will affect workers and residents around the project area (apartment buildings and condominiums Anping Sacomreal). At the distance of 40m, 100m, 200m resonance noise of construction equipment have reached QCVN 26-2010 (6 18h).
