At the oil drilling site, the noise is mainly the mechanical noise generated by the operation of the power unit and its supporting equipment of the drilling rig. High-intensity noise may cause harm and disturbance to residents and operators around the site. The photo shows the sound barrier on Shell Drilling Site. For the noise and vibration equipment on Floor 1, sound barriers were set up around the platform and at the factory boundary to meet the standard requirements for noise at the factory boundary and surrounding sensitive points.
