Environmental noise, usually called Noise pollution in technical venues, is displeasing human or machine created sound that disrupts the environment. The dominant form of noise pollution is from transportation sources, principally motor vehicles. Principal noise health effects are both health and behavioral in nature…

Introduction

Furthermore, stress and hypertension are the leading causes to health problems, whereas tinnitus can lead to forgetfulness, severe depression and at times panic attacks. Passive noise control involves constructions done to reduce the noise level in roadways and busy roadways. The treatments include insulation, silencers, vibration mounts, damping treatments, absorptive treatments and conventional mufflers like the ones used on today's automobiles. The Bradford City Centre is one such place where the noise levels are very high. This report aims at making a comprehensive study about the present noise levels and the expected noise levels after the transformation that it is to undergo.
In recent years, traffic noise - the unpleasant, unwanted sounds generated on our nation's streets and roadways - has been of increasing concern both to the public and to State officials. At the same time, modern acoustical technology has been providing better ways to lessen the adverse impacts of roadway traffic noise. Many of these acoustical techniques are now being employed by government agencies, roadway planners and designers, construction engineers, and private developers to reduce the impact of this noise. The loudness of sounds (that is, how loud they seem to humans) varies from person to person, so there is no precise definition of loudness. ...

Although the prime objective of a control system is to have optimum performance yet without any adjustment it is rare indeed. Usually we have to compromise among many conflicting and damaging specifications and have to adjust the system parameters to achieve a suitable performance although it is not possible to obtain all desired optimum specifications. The control system adjustment or…

The rate of heat loss from the building and the annual energy requirement is to be estimated. The insulation of the building is one of the factors that needs to be improved in order to determine the heat loss in the building and the energy requirement. A great amount of energy demand is connected to the built environment. The interaction between the different conditions, control strategies and…
