Vibrations impinge on the ear drum of a human or animal and setup a nervous disturbance, which we call sound. When the effects of sound are undesirable that it may be termed as “Noise”. Noise from industry, traffic, homes and recreation can cause annoyance, disturb sleep and affect health. Thus, sound is a potentially serious pollutant and threat to environmental health. The response of the human ear to sound depends both on the sound frequency (measure in Hertz, Hz) and the sound pressure, measured in decibels (dB). A normal ear in healthy young person can detect sounds with frequencies from 20Hz to 20,000 Hz. Noise measurements are expressed by the term Sound Pressure Level (SPL) which is logarithmic ratio of the sound pressure to a reference pressure and is expressed as a dimensionless unit of power, the decibel (dB). The reference level...

...The effects of noise pollution (final draft) Noise pollution is a common phenomenon in our daily society. It is any sound that is interfere with human life. The noise is commonly produced by vehicular traffic, construction sites and other sources. It is the unpleasant sound that may affect nearly every aspect of life. It is unlikely produce the physical substances such as environmental pollution, but it will cause a lot of damages to both human and animals in many ways. Noise pollution has serious effects on human health. This is a matter of great concern to the society. Hearing loss is the most probable outcome to the people who are always under this type of pollution. The sustained and loud noise can cause hearing loss. We may suffer from hearing impairment if we are exposed to this excessive noise for a long time. Therefore, occupational hearing loss is one of the common problems among the industrial diseases. Construction workers are most likely to be influenced by the noise pollution among all other jobs. The noise is hazardous to hearing in the construction industry. They are exposed to the excessive noise pollution in a long period. By retirement, many of them are having a noticeable hearing loss problem. This type of permanent hearing loss can never be repaired. It is sadly that it is impossible to restore hearing. Hearing impairment may lead to some accidents, because the people cannot hear the waning signals from others clearly, they may ignore the dangerous. It...

...CONTROLLING NOISE AND AIR POLLUTION FROM TRAFFIC: A CASE STUDY 1. INTRODUCTION Pollution is defined as the introduction into the natural environment that cause adverse change. Pollution can take form of chemical substances or energy, such as nose, heat or light. Pollutants, the components of pollution, can be ether foreign substances/energies or naturally occurring contaminants. Pollution can kill plants and animals, it may be muddy landscapes, poison soils, waterways, noise, air, etc. People are also regularly harmed by these pollutions. Long-term exposure to these pollutions may lead to any diseases such as lung cancer. Chemicals that accumulate n top predators can make some species to eat for humans. In fact, more than one billion people lack access to clean water these days and 2.4 billon don’t have enough clean sanitation, putting them at risk of contracting deadly diseases. 1.1 Objective of the Study This study aims to examine the problem of noise and air pollution from traffics in the wake of its all effect on the life of the people by planning on how to control pollution at source to the maximum extent possible with due regards to technological achievement and economic viability as well as sensitivity of the receiving environment.

...No matter the demographic of people being questioned, we as people can all relate to the need for clear and distinct territories, a sense of privacy and a desire for personal space, however as individuals we all experience the same events and situations entirely differently, depending on such factors as pervious experiences, personality type, cultural influences, age, socio-economic status, gender, etc. When taking into account the above referenced “factors” a clear and distinct definition of the key concepts , being discussed, is in order. Territory, Privacy, and Personal Space: Concepts such as Territory, privacy, and personal space take on a new meaning in relation to the ever-increasing population density. Here we take a brief look at the definition of each concept, as well as how each concept relates to high-density populations. Territory: The term territory refers to an area of land under the ruler ship or jurisdictions of a governing power (weibster.com). A similar term called, Territoriality refers to manner in which both Humans as well as animals utilize and defend, usually via physical acts of aggression, their physical space. (Territoriality, 2004). According to Abu-Ghazzeh (2000) “no area can be called a territory unless it is characterized by its owner's personal means of identification and unless it constitutes a component of the social behavior of its related group” (para. 1). What this means is that, behaviors are the catalyst to what truly define...

...important to our material resources this earth has created for us? This is the essential question so many are asking in today’s society. Many decades have been addressing the ecological impacts of consumptions and production therefore air quality has improved, waste and industrial pollution has been controlled more and products are more proficient with more informed consumers to boot. As we know these are steps in the right path, however more must be done to manage consumption and production of our material resources. Elemental changes are needed in how natural resources are removed and the way products are produced, dispersed, used and disposed of. Action is needed at all levels of society from individuals and industry through to central and local administration in order to reverse past and current trends and live within biological limits. Thus in this thesis, I will discuss two material resources of consumptions and productions that humans are constantly producing and consuming and how we can potentially decrease them. The first consumption called deforestation often leads to a production such as farming. The second consumption to be discussed is urban sprawl, which leads to the production of water pollution. However, let us first define deforestation and urban sprawl. “Deforestation commonly defined as the elimination of trees and other plants from forest areas more quickly than they can be replanted or rejuvenated naturally. Urban sprawl is the spreading of urban and suburban...

...1.0-Thesis statement Urban planning is the political and technical process focused on utilization of urban land and designing of urban environment in ensuring and guiding the orderly development of communities and settlements (Levy, 2011). The entire urban planning process entails analysis and research, architecture, public consultation strategic thinking, urban design, policy recommendation, management and plans/policy implementation. One of the most notable aspect urban planning covers the housing planning and transportation planning. With increasing need for sustainable development in the urban, diverse policies are adopted by region, community, or State in ensuring effective urban planning. Thus, this proposal will offer a comparative analysis of policies and political aspects of transportation planning and housing planning with particular interest in the imperative role the urban planning has played in ensuring sustainable development. 2.0- Annotated Bibliography Ankner, W. (2005). Revisiting Transportation Planning. Public Works Management & Policy, 9(4), 270-277. The author revisits the contextual reality surrounding the U.S. transportation planning. Ankner (2005) examines the existing transportation planning models as well as decision-making tools, in supporting the view that the U.S. urban planning framework is either too divided or too limited in scope, thus, incapable of attaining the intended transportation goals. The source will inform the study by availing...

...everyday life, especially during participation in recreational activities such as playing in bands, seeing a very loud live show, shooting weapons, listening to headphones, mowing lawns and using woodworking tools. Sounds that are heard that are less than 75 db, are less likely to cause hearing loss, when sounds that are above 85 db can affect human hearing. If the sounds are louder, the worse it is for hearing and the less time it takes for NIHL to occur. Average db rating for a normal human conversation is 60 db, which is unlikely to cause hearing loss, when firing a shotgun at 150 db can cause harm to hearing. The distance between a human and a loud sound source and the time of the exposure plays a huge role in NIHL, so it is best to avoid noises that are too loud for too long and to avoid being close to them. + What parts of the human hearing system are affected? + What are the symptoms and effects of NIHL? Humans begin to slowly loose their hearing when exposed to loud sounds. Most humans will not notice and will simply ignore the symptoms of NIHL until they become hard to not notice. As time goes by, people that are effected by NIHL will notice that everything they hear will sound unclear or muffed and eventually request the other person to speak louder during a conversation or turn up the volume on their headphones. Most people that are heavily effected by NIHL will be using hearing aids to “magnify” the sounds to help them hear sounds during daily activities. NIHL has...

...paper in which you analyze the effect of population density and noise on individuals. As a part of your analysis be sure to address the following items: Describe the concepts of territoriality, privacy, and personal space. Examine how the concepts of territoriality, privacy, and personal space have become increasingly important as populations become denser. Clarify the effect nature (e.g., zoos, parks, gardens) has on individuals living in urban environments. Describe the concept of noise and examine the effect that it has on individuals. Examine at least two strategies that can be used to reduce noise in the workplace or in the living environment. The Effects of Population Density and Noise Paper The first line of strategy is to do what an individual can do to minimize the noise pollution he or she can control in their environment. For instance, if an individual lives next to a noisy freeway or airport, he or she can invest in double panel windows in their home (cite). The double panel windows action server two purposes, one purpose is keep the noise out and the purpose is keep the hot sun and cold winter out (cite). For example in the home individual can control noise pollution by their home by turn off television when not been watched and radio and stereo at low volume. Another strategy to minimize or reduce noise pollution is to try to minimize noises directly from the source. In the workplace or industries environment...

...How do your pets react to loud noises like thunder and fireworks? I've seen reactions from nonchalant to extreme terror. My friend's Golden Retriever likes to wrap himself around whatever human is available, shaking in fear. A neighbor's dog acquired super-canine powers and actually ate through the fence and ran into a busy street. Fortunately someone brought her home safe, but others have not been so lucky. Dogs, cats and other animals react like this because they are extremely afraid and anxious, thinking that you can make the noise stop or that they can run away from it. Here are some tips to help noise-sensitive animals deal with the noises of summer: Do not: Above all - do not punish your pets for annoying or destructive behavior brought on by noise anxiety. When pets get their adrenaline...

...Unit 45: Transport systems and the environment In this report I will be describing the different forms of impact that transport systems can have on the environment Air pollution This is one of the most obvious impact that transport systems can have on the environment. Many forms of transport rely on burning ‘unclean’ fuels such as petrol and diesel. Cars and buses are among the main culprits for polluting the environment. The emissions that these vehicles release can be potentially harmful to people’s health. A huge percentage of people living in busier cities such as London, Beijing and Los Angeles die or are seriously affected by diseases and complications that the high concentration of emissions cause. Noise Pollution Cars, buses, trains and planes when moving make noise. This is known as noise pollution. Many people choose not to live in busy cities because of the high level of noise pollution. Visual Intrusion As I have mentioned above, many people choose not to live near a busy road, in a city centre or near an airport because of the loud noise that is associated with these places because of the amount of traffic that goes through them. However it is not just the noise pollution that can be a factor. These places need to be lit up all day and all night so that drivers, pedestrians and pilots can see where they are going as the safety of these people is paramount. The problem with that is that people living near these sort of areas may find it hard to sleep at night...
