Impact assessment of noise pollution in relation to damage on human in Sydney and the precarious noise pollution of Dhaka

Elevated uncomfortable noise develops much direct and indirect health condition. Major consequences originating from noise includes high blood pressure, mental illness, cardiovascular diseases leading to eventual mortality. In Bangladesh, Dhaka city in particular the rampant pressing of hydraulic and other horns on a regular basis slowly developing permanent deafness, a catastrophic consequence is waiting to happen unless authorities are urgently acting to ban hydraulic horns. In Europe alone more than 50,000 deaths are cause by unacceptable noise pollution (www.transportenvironmnet.org). WHO recommendation (2009-2019) has identified night time noise is more injurious to heath if threshold level exceed 40 decibel (dB) and is more likely to develop sleep disorder and insomnia. Regular night time exposure above 55 decibel (dB) will trigger blood pressure symptoms. As the wisdom increases, evidence about the danger of acoustic contamination has become evident with increasing public awareness. Due to increased community demand, health and safety issues the government has become more active in devising effective regulatory measures as well as its effective application and enforcement in the western countries and Bangladesh should their footsteps without any delay. It is great news that the danger of acoustic contamination is widely recognized and its negative consequences understood by the local as well as international community, which are forcing everyone engaged in noise producing activities to take appropriate measures to keep noise level to acceptable level. The world as well as Australia is now more intelligent with the gift of knowledge and technological advancement. Traditionally Australia has taken leading role in many sectors and the time is ripe now

Effect of Noise on Human Psychology in Public Spaces of Dhaka City

© 2019, IRJET | Impact Factor value: 7.211 | ISO 9001:2008 Certified Journal | Page 6072 Noise pollution continues to pose a major health threat for Bangladesh, especially in cities and particularly in Dhaka city. Much discussion has occurred in the media over the many serious environmental problems that Bangladesh faces which includes water and air pollution, harmful effects of polythene bags etc. Although it is mentioned occasionally, noise pollution has not received serious attention in the past. Recent studies show high levels of noise in various points in the urban centers of Dhaka, Sylhet and Khulna. To many Dhaka residents, it may be considered more of a necessary aggravation than a serious problem that can be addressed. Noise pollution is not only an aggravation, but also a serious risk. The WHO and GoB have established guidelines and standards for maximum allowable levels of noise above which people are harmed; it is widely known that in many parts of Dhaka city, those levels are regularly exceeded. People of Dhaka city mostly suffer from the bad effects of noise pollution. Dhaka is one of the most heavily populated metropolitan cities of the world with significant commuter flows.

Willingness to pay for noise abatement in Singapore

Willingness to pay for noise abatement in Singapore

As discussed in Chapter 5, respondents must accept the policy context provided in the questionnaire and believe that their responses will inform future policies to reduce noise so that the stated preference survey can elicit the true preferences of respondents. This chapter identified two types of anomalous responses, namely, protest respondents and respondents who did not believe that the survey was consequential. In the field surveys, both types of anomalous respondents amounted to around a quarter of the sample size, which is high as compared to other studies (see, for example, Meyerhoff & Liebe (2010) for a meta-analysis). The demographic characteristics that lead to a higher likelihood of these anomalous responses were examined. The relatively high rates of anomalous response may also have been caused by public sentiment. While this factor is not fully examined in this thesis, the ground sentiment in Singapore and its potential impact on the number of anomalous respondents in this survey are discussed in Section 12.2.1. In subsequent analysis, the differential effect of including and excluding these anomalous respondents from the sample is examined.

The Legal Regime of Noise Pollution in Nigeria

The Legal Regime of Noise Pollution in Nigeria

energy, such as noise, 4 heat or light. 5 Noise pollution is one of the environmental hazards affecting humans as well as climate. 6 In most urban areas of the third or developing countries of the world especially Nigeria, there are lots of noise pollutants which include noise from exhaust cars, industrial as well as home generating plants. In advanced countries however, scientific experimentations like launching and re-lunching of rockets, bombs and satellites sounds constitutes a major climate pollutant (Kapoor & Singh, 1995; Nagi, Dhillon, & Dhlwat, 1999). Against this background, this paper examines noise as a factor harmful to the environment with focus on Nigeria. The paper looks at noise pollution in Nigeria and the legal regime relating to the problem. The paper examines how environmental law and other relevant sources of law endeavoured to tackle noise pollution in the country.

What Does “Noise Pollution” Mean?

What Does “Noise Pollution” Mean?

Since the enactment of Directive 2002/49/EC of the European Parliament and of the Council of the European Union [19], every country in the Union must carry out strategic noise maps for all its cities with 250,000 inhabi- tants or more, communicate their findings to the Council of the European Union, put in practice concrete actions to improve environmental acoustic quality, and review and renew strategic maps into a given period. Ten years later, although there are still difficulties with its implementation and in the harmonization of methodologies, the usefulness of the strategic noise maps is not questioned [20] [21]. Moreover, there are several national and pro- vincial regulations requiring strategic noise maps in cities with less than 10% of the threshold number stated by the EU Directive [22]. As stated by Bañuelos [21]: “A strategic noise map, the action plan and the subsequent management are opportunities to solve noise problems.” He also said: “the high initial cost for the Administra- tion to build a strategic noise map is not on the map itself, but on the corrective measures that must be imple- mented because of him.”

REVIEW ON ROAD TRAFFIC NOISE POLLUTION

REVIEW ON ROAD TRAFFIC NOISE POLLUTION

Transportation sector is one of the main contributors to noise in the urban areas. The traffic noise environment in Balasore, a city of Orissa, India in terms of standard noise offensives, community response and community health effects are worked out in the present study. A preliminary survey adopting questionnaire method amongst 212 local inhabitants also carried out to gather secondary information about the suffering of noise related physical condition problems. Noise pollution is not properly recognized despite the fact that it is steadily growing in Developing countries like India and in particular in the state Orissa. It is well conventional now that noise is a potential hazard to health, communication and pleasure of social life. Transportation sector is one of the main contributors to noise in this urban area. The present study explicitly reveals that the noise levels are greater than the permissible limit in all the six locations including 24 sites.

COMPARATIVE STUDY OF NOISE LEVEL IN SURAT CITY

COMPARATIVE STUDY OF NOISE LEVEL IN SURAT CITY

pollution and its consequent influence over the life quality of human beings may be considered as a "hot topic" in scientific research. The increasing number of living people and vehicles has led to major concern about "noise pollution". Noise is defined as unwanted sound. Sound is a form of energy which is emitted by a vibrating body and on reaching the ear causes the sensation of hearing through nerves. Sounds produced by all vibrating bodies are not audible. The frequency limits of audibility are from 20 Hz to 20,000 Hz. The discrimination and differentiation between sound and noise also depends upon the habit and interest of the person/species receiving it, the ambient conditions and impact of the sound generated during that particular duration of time. Every exposure to loud noise destroys some cells, but prolonged exposure damages a larger amount of cells, and ultimately collapses the Organ of Corti, which causes deafness. Noise pollution is a major problem for the quality of life in urban areas [1]. Traffic noise is considered as one of the important sources of noise pollution that adversely affects human health in residential urban areas [2-4]. Permanent hearing loss by long-term exposure to noise has been reported by Nelson [5]. It is considered one of the most widespread environmental issues all over the world. It is considered a serious issue because of its harmful impacts on citizens and public health. Noise adversely impacts development as a result of its direct and indirect effects on life activities. Exposure to high noise levels is among the key causes of human mistakes leading to increased accident rate [6]. These levels have reached unacceptable limits locally and internationally. Pathak et al. [7] carried out a study on traffic noise pollution at four areas categories (industrial, commercial, residential and silence zone) in the city of Varanasi, India. They found that 85% of the people were disturbed by traffic noise; about 90% of the people reported that traffic noise is the main cause of headache, high blood pressure problem, dizziness and fatigues. To prevent and control the sources of the noise, the Govt. of India has already published the rules known as Noise Pollution (Prevention & Control) Rules, 2000 which is applicable to entire country. To implement these Rules under Section 2 (c) Authority is prescribed, accordingly the Police Commissioner or District Superintendent of Police are declared as Authority. According to this act the environmental quality standards are prescribed which is as under

Effect of Road Traffic Noise Pollution in Cuddalore Town: A Case Study

Effect of Road Traffic Noise Pollution in Cuddalore Town: A Case Study

The noise originates from human activities, especially the urbanization and the development of transport and industry. Though, the urban population is much more affected by such pollution, however, small town/villages along side roads or industries are also victim of this problem. Noise is becoming an increasingly omnipresent, yet unnoticed form of pollution even in developed countries. According to Birgitta and Lindvall (1995), road traffic, jet planes, garbage trucks, construction equipment, manufacturing processes, and lawn mowers are some of the major sources of this unwanted sounds that are routinely broadcasted into the air. Though noise pollution is a slow and subtle killer, yet very little efforts have been made to ameliorate the same. It is, along with other types of pollution has become a hazard to quality of life. Kiernan (1997) finds that even relatively low levels of noise affects human health adversely. It may cause hypertension, disrupt sleep and/or hinder cognitive development in children. The effects of excessive noise could be so severe that either there is a permanent loss of memory or a psychiatric disorder (Bond, 1996). Thus, there are many an adverse effects of excessive noise or sudden exposure to noise. In India, the problem of noise pollution is wide spread. Several studies report that noise level in metropolitan cities exceeds specified 60dB. Murli and Murthy (1983) also found that traffic noise in Vishakhapatnam exceeds 90dB even in morning hours that acts as a source of nuisance. The noise pollution is not a unique problem for developing countries like India only. In China, till third century B.C., instead of hanging men for dangerous crimes, noise was used for their torturing. The worrisome effects of noise are dangerous enough that noise problem is considered next to crime by certain countries (Kapoor

Is Mehrabad Airport a Brownfield Site?

Is Mehrabad Airport a Brownfield Site?

On the plus side, the accumulation of dwellings in district 9 and inappropriate distribution of settlement pat- terns in this district prevent any sort of further development around Mehrabad airport. Based on a comprehen- sive plan to reduce environmental pollution in big cities, The Ministry of Transportation and Urban Develop- ment (MTUD) has been given the responsibility for shifting all flights from Mehrabad airport to Imam Khomeini International Airport (IKIA) until the end of the “fifth development plan” 1 (ICANA, 2011). However, owing to current infrastructural constraints at IKIA such as the long distance to the city and week public trans- portation system, the process of airport transfer will definitely last for a while.

Study of Noise Pollution in Nashik City

Study of Noise Pollution in Nashik City

D) Noise Pollution - The Situation Today : In urban localities all over the world, noise pollution has been recognized as a major factor affecting public health and well-being. It is an ever-growing nuisance. Man-made sources are mainly responsible for increasing the ambient noise level in urban localities. Automobiles, industrial units, low flying aircraft and loud speakers have been recognized as a major source of noise affecting a large number of peoples. Thickly populated, poverty-stricken third world countries are however, the most affected ones, wherein the ill effects of noise pollution are rarely given serious attention. A survey in Delhi, Bombay and Calcutta conducted in 1988 revealed daytime noise levels ranging between 60 dB to 90 dB in residential localities. Many times during the day this level exceeded 100 dB. Near aerodromes, railway tracks, busy highways and industrial establishments a noise ranging between 95 to 105 dB has been recorded during most of the daytime. On the basis of extensive studies World Health Organization has recommending permissible noise levels for residential, industrial, commercial localities and silence zones. [6 ]

A  Review on Noise Pollution due to Traffic

A Review on Noise Pollution due to Traffic

[2] Wats and Godfry (1999) studied that there is considerable interest in the use of sound absorptive materials for reducing noise reflected from noise barriers although there is little reliable information on their effectiveness in practice. The primary object was to determine, under carefully controlled measurement conditions, the effects on roadside noise levels of applying sound absorptive materials to the traffic face of noise barriers. Measurement of traffic noise were made close to the roads both behind and opposite the barriers with the panels in the normal position and then measurements were repeated after the panels had been reversed such that the reflective side faced the traffic. It was found that at both sites there was an increase of noise of generally less than 1 dB when the barrier face was changed from sound absorptive to reflective.

There are several environmental concern in Environmental Quality (Sewage and Industrial Effluents) Regulations 1979 by CIDB for water pollution which are: 1) prohibition against new and altered sources of effluent discharge and acceptable conditions of discharge into inland water. Otherwise, in Pesticides (Highly Toxic Pesticides) Regulation 1996 stated about duties about person using or handling highly toxic pesticide under water pollution environmental concern. In Environmental Quality (Perbadanan Putrajaya) (Water Pollution Control) Regulations 1998 also stated about water pollution which is about new sources of discharge prohibition against new and altered sources of effluent discharge, acceptable conditions of discharge into inland waters prohibition against discharge of effluent containing certain substances and prohibition of discharge effluents. Transportation, storage or disposal of pesticides or pesticide containers also environmental concern under legislation of Pesticide (Pest Control Operator) Rules 2004.

COMMERCIAL AREAS OFALLAHABAD CITY AND ITS IMPACT ON CONTOUR TRAFFIC NOISE POLLUTION OF THE THE ENVIRONMENT

COMMERCIAL AREAS OFALLAHABAD CITY AND ITS IMPACT ON CONTOUR TRAFFIC NOISE POLLUTION OF THE THE ENVIRONMENT

Allahabad city covers a total area of 63.07 sq km with a population of 9, 90,298 at an altitude of 98m above sea level. The Allahabad District is located at 25°26´N/ 81°50´ E. The population of Allahabad presents all types of living standards ranging from business class to labour, official to student and illiterate to highly educated. The city also houses many educational institutions and it has become a hub of administration too. Its rapid growth in trade and commerce as well as developing activities related to modernization and high standard of living make it a perfect place to study the noise impact. A sudden spurt of vehicles has occurred due to influx of large population resulting in increased traffic volume whereas the road infrastructure remains the same. The noise levels were measured with the help of a sound level meter (TES-1350A).The wind influence on the microphone was lowered by placing a special sponge on the top of the microphone. The noise levels was recorded every 5 minutes and was measured in Decibel on an A weighted scale (dBA) since this scale measures sound level in approximately the same as the human ear [11]was used for monitoringnoiselevels.the data measured were evaluated for Leq (combined noise level). The following equations were used to evaluate Leq

“Noise pollution”: an overview

“Noise pollution”: an overview

Road traffic is the most widespread source of noise in all countries and the most prevalent cause of annoyance and interference. It is directly proportional to the volume of vehicles. Increasing of population is increasing of vehicles and hence increasing of Noise pollution. The major sources of noise in automobiles are exhaust, intake, engine and fan, and tires at high speed. The noise output of all components increases with speed. The Road traffic noise not only depends on volume of vehicles and also depends on several factors; some of them are Road conditions, Traffic clearance, Condition of vehicles, Speed of the vehicle and the people living near roadside (highway) are mainly exposed. For example the study conducted around the main roads inside the urban perimeter of Curitiba, simultaneous measurements were done regarding noise levels, vehicle flow and traffic composition and thus some mathematical models have been developed in order to estimate those sound pressure levels. It was confirmed that people living or working in these areas are exposed to noise levels beyond the legislated norms (Calixto et al., 2003) and the two models for predicting in-city road-traffic noise pollution of Mashhad were obtained by Rahmani et al., (2010).
