Shannon and Weaver were concerned with noise in the communications process. Noise‚ Weaver said‚ "may be distortions of sound (in telephony‚ for example) or static (in radio)‚ or distortions in shape or shading of picture (television)‚ or errors in transmission (telegraph or facsimile)‚ etc." Shannon and weaver

Engine exhaust noise is controlled through the use of silencers and mufflers. Generally speaking‚ there is no technical distinction between a silencer and muffler and the terms are frequently used interchangeably. A silencer has been the traditional name for noise attenuation devices‚ while a muffler is smaller‚ mass-produced device designed to reduce engine exhaust noise. 1.2 SILENCER SELECTION FACTORS The use of an exhaust silencer is prompted by the need to reduce the engine exhaust noise. In most applications

WATER POLLUTION — any contamination of water that has deteriorated its quality to living things. * SOURCE: There are many causes for water pollution such as effluent outfalls from factories‚ refineries and waste treatment plants. More to that‚ the contaminant that enter the water supply from the soil or groundwater systems. Soils and groundwater contain residue of human agricultural practise and improperly disposed of industrial wastes. Other than that‚ the habits

communication gathered from various articles. Noise Noise is the biggest common barrier in communication. It can be internal and external. It acts as an interference that occur during a communication process and prevents us from listening effectively. Here are the examples of internal and external noises. Internal noise begins with the person himself. For example‚ instead of noises that can be heard‚ internal noise occurs in a person’s mind. Noises that can be heard‚ such as a construction which

Adviser and Physics teacher A. INTRODUCTION Noise pollution disorders the balance or activities in mankind or habitat. The source of most outdoor noise worldwide is mainly machinery‚ vehicular transportation‚ aircraft‚ and trains. Poor urban planning tends to worsen noise pollution‚ since adjacent industrial and residential structures can result in noise pollution in the residential areas. Since over exposure of noise pollution may produce stress or hypertension for the person‚

Introduction: The problem of Noise Induced Hearing Loss (NIHL) has been an ongoing issue in the industrial environment. Even with the best hearing loss prevention program the human factor‚ or non-compliance is the primary reason for this issue. The worker can be given periodic training in the causes and prevention of irreversible hearing loss‚ supervisors can be vigilant in ensuring that workers wear appropriate personal protective equipment in noise environments‚ and periodic audiometric
