Noise Control - Precautions at the Design Stage

The cost of producing a quiet factory or plant varies with the type of industry.but may be between 0.5 and 2% of mpital cost for plant on existing sites in industrial areas.-Should the plant be on a green eld site then the costs could be doubled.Noise control costs money and must be allowed for when costing a project.failure to do so inevitably leads to either:(a) over expenditure or (b) excesive noise levels.Noise control applied after commissioning inevitany costs more and in some cases becomes impracticable or uneconomic.'Works design staff should make provision for noise control at the design stage.
