What construction environments require hearing protection?

 If workers are exposed to levels above 85 dBA, the employer must consider using engineering and administrative controls to reduce noise at the source or along the path to the worker. If it is not possible to control noise at the source or along the path, the employer can consider using personal protective equipment (PPE) such as hearing protection devices (HPDs) to control noise at the worker.
