Industrial Noise Control: Fundamentals and Applications

The opinions, findings, and conclusions expressed herein are not necessarily those of the National Institute for Occupational Safety and Health, nor does mention of company names or products constitute endorsement by the National Institute for Occupational Safety and Health. PREFACE Employer and employee awareness of the problems of Industrial noise has increased notably in the past decade, Industry's concern about noise, especially since the mids, has been growing steadily. Industry has responded to the new interest in noise reduction, but has encountered difficulties in correcting individual noise problems and implementing company-wide noise r e duction programs. Company personnel who may have little or no understanding of the causes or solutions of the problems of noise may be asked to select a noise control method or device, to choose noise control materials, to use noise measuring instruments, or to decide whether to call upon a qualified consultant. In this dilemma, industry's need is clear: practical information about noise control, information based on methods that have been tested and found successful in terms of effectiveness, time, and cost in achieving an acceptable noise environment in in dustrial plants. NIOSH 7 5 - 1 8 3 ] 3 which included essential information about noise control techniques and a collec tion of case histories of successful noise control projects in industrial plants.

The development of technology has lead to widespread increase in machinery and also increase in the number of industries, with this also came the noise. Noise interferes with the efficiency of the work done by the employees whose work is highly skilled and involves decision making. The risk involved in exposure to the noise for 8 working hours is very high. In this paper, we discuss the mechanisms which are used in the industries for reducing the amount of noise in a refinery; engineering applications and protective techniques which reduce the impact of noise; administrative techniques reducing the amount of exposure of noise to the worker.

Noise control or noise mitigation is a set of strategies to reduce noise pollution or to reduce the impact of that noise, whether outdoors or indoors. The main areas of noise mitigation or abatement are: transportation noise control, architectural design, urban planning through zoning codes , [1] and occupational noise control. Roadway noise and aircraft noise are the most pervasive sources of environmental noise. Social activities may generate noise levels that consistently affect the health of populations residing in or occupying areas, both indoor and outdoor, near entertainment venues that feature amplified sounds and music that present significant challenges for effective noise mitigation strategies. Multiple techniques have been developed to address interior sound levels, many of which are encouraged by local building codes. In the best case of project designs, planners are encouraged to work with design engineers to examine trade-offs of roadway design and architectural design.

Unfortunately, in most industries, occupational hygienists are seldom in the position of To fully understand noise control, fundamental knowledge of acoustics is required. The later chapters, in particular, include research with fundamental, well-established tenets of noise control, a careful selectivity must be so that conversion market and a wide variety of applications.

Industrial Noise Control: Fundamentals and Applications

Стратмор бросил взгляд на лежавшего в беспамятстве Хейла, положил беретту на столик рядом со Сьюзан и крикнул, перекрывая вой сирены: - Я сейчас вернусь! - Исчезая через разбитое стекло стены Третьего узла, он громко повторил: - Найди ключ. Поиски ключа не дали никаких результатов. Сьюзан надеялась, что Стратмору не придется долго возиться с отключением ТРАНСТЕКСТА. Шум и мелькающие огни в шифровалке делали ее похожей на стартовую площадку ракеты.

Он попытался определить акцент - может быть, Бургос. - Вы набрали правильно, - сказал он осторожно, - но это служба сопровождения. Звонивший некоторое время молчал. - О… понимаю.

Noise Control Mechanisms for Industry Operations—A Review

Вы можете читать все, что пожелаете, - без всяких вопросов и запросов. Вы выиграли. - Почему бы не сказать - мы выиграли.

Плеснув водой в глаза, Беккер ощутил, как стягиваются поры. Боль стала утихать, туман перед глазами постепенно таял. Он посмотрелся в зеркало. Вид был такой, будто он не переставая рыдал несколько дней подряд.

 Ничего не сделал? - вскричала Сьюзан, думая, почему Стратмор так долго не возвращается.

В том, что вы просто так отдали ей кольцо. - Нет. Я сказала, что нашла его в парке.
