This section contains noise and vibration evaluation of potential impacts during construction and operation phases. However, the main concern is on the noise and vibration generated by the project activities during construction phase than the operation phase when most of the processes and equipment are typically enclosed.
The noise levels created by construction equipment will vary greatly depending on factors such the type of equipment, the specific model, the operation being performed, and the condition of the equipment. The equivalent sound level (Leq) of the construction activity also depends on the fraction of time that the equipment is operated over the time period of construction. This section provides information on typical levels of noise and vibration generated by various construction equipment and assessment of potential impacts due to their operation.
