* Converting into dB was done based on formula provided in para 57
323. 
As shown, the results of calculation of vibration level (Table 14), vibration from 
construction activities at this stage will not impact on people living in surrounded areas and 
for structures since it is below the standard of 72 dB for the daytime. Anticipated vibration 
levels at the closest distances of 30 meters (Syrdarya and Namangan sites) is below 
standard. It will not also impact on residential buildings as well, since the highest vibration 
level will not exceed 0.16 in/s or 71 dB. This level is below the standards for historical places 
as well - 94 dB. Therefore, there is no impact on the closest historical objects located at a 
distance of 500 meters away from the project site in Surkhandarya province.
324. 
Therefore, the above described impacts on air quality, noise and vibration will be 
temporary and can be mitigated by the implementation of the recommended measures.
