pump noise level reduction method ppt
Introduction
Under the Noise Control Ordinance, noise generated from industrial or commercial activities should comply with the noise standards as stipulated in the relevant Technical Memorandum. It is generally recognized that operation of pumping systems is one of these noisy activities. This booklet highlights the importance of planning against noise problems. It gives a brief description of potential noise problems associated with pumping systems and provides guidelines on practical noise control measures that are applicable for new designs and for retrofitting existing designs.The reader is reminded that compliance with the recommendations of this booklet does not necessarily mean compliance with the legislative requirements. Besides, the recommendations made in this booklet are not exhaustive. Alternative solutions to achieve the same results may exist. The reader is therefore recommended to consult independent experts throughout the process for ensuring the use of proper and cost effective noise control measures. This booklet is designed mainly for reference by restaurant operators, building operators and those pumping contractors who do not have sufficient noise control knowledge. Architects, building services engineers or other relevant professional parties may also use it as a checklist to ensure that proper measures will be taken to avoid noise problem in designing pumping systems and locating pumping equipment. The main contents are written in plain language illustrated by schematic diagrams for easy understanding by a layman. The focus is on practicable measures. More technical information can be found in appendices. The reader is also advised that there is another booklet "Good Practices on Ventilation System Noise Control" available which describes ventilation system noise problems and possible solutions.
