The sweetest music, if it disturbs a person, who is trying to concentrate or to sleep, is noise for him, just as pneumatic riveting hammer is noise to everyone.
In other words any sound may be noise if circumstances cause it to be disturbing. It has its effect on all living things. The problem of noise pollution carries its effect on human beings, animals and birds equally. Studies about the noise pollution reveals that hearing loss, insomnia, blood pressure, cardiovascular, digestive problems, hypertension, headache, annoyance and irritation are common ailments caused by noise amongst fully grown human beings, while dizziness and neurophysiologic reactions are found in children and on the other hand, the problem of increasing heart rates, blood pressure in animals and disturbance in breeding system have been noticed as important ailments.
The studies on noise pollution also prove that normal tolerance of noise in human beings lies between dB and exposure to noise of more than 90dB may result in permanent hearing loss.
Taking these harmful ill effects of noise pollution into consideration, the Noise pollution regulation and control rules was passed to keep a control on the noise levels. The method by which the research is done is called research method, and the philosophy behind that practical method is called research methodology.
Research methodology is thus broader as it is study of practical method. The implementation of the statutory provisions regarding noise pollution has significant consequences, only when implemented properly. Moreover, the author has identified the challenges that need to be countered to make the laws effective. Nevertheless, if noise pollution can be reduced it will have set the stage for e environmental management; an improvement in environmental quality would prevail.
To study the various provisions laid down regarding noise pollution in India. With its comprehensive and exhaustive coverage on this area of law, it is expected to also serve as a useful reference for practicing lawyers, social activists, researchers and students working in various fields, such as, human rights, as also the students of law and environment.
Singal This book discusses the basics of acoustic propagation, reviews the problem of noise generation over all national and international situations and gives various techniques available for noise measurements and assessment. Pollutant - Something that pollutes; a pollutant or a group of pollutants Principle - A basic truth, law, or assumption: the principles of democracy. Pay - To bear a cost or penalty, for example in recompense Noise — when sound becomes annoying.
This study utilized analytical method of research which falls under the types of research, where I as researcher have used facts and information already available and analyzed these to make a critical evaluation of the data available regarding noise pollution in India. Additionally the research work determines the causes of noise pollution in India, and its effects and impact on the whole environment and on human health and how can it be controlled by the legal provisions and the judicial review to attain a sustainable and pollution free environment.
The researcher has relied on primary sources related thereto and Secondary sources like books written by various eminent authors and articles found in the journals and websites, e-journals. Use of internet also became very relevant to find out the most updated, relevant and apt information which helped me in exploring the subject from various dimensions. Chapter 3: Deals with all the statutory provisions for prevention noise pollution in India Chapter 4: Deals with Judicial Pronouncements in Noise Pollution, Studies in India and Controls and suggestions for prevention of noise pollution.
Chapter 5: Deals with conclusion of the research paper. It only gives a view about the cause, effects, and legal provisions of noise pollution in India.
Further in the third week the researcher has dealt in the formation of chapterisation vide analyzing the issues and problems in detail. Consequently in the fourth week the researcher took 5 days for writing conclusion and suggestion and thereby took 2 days for compilation and binding. Sound which pleases the listeners is music and that which causes pain and annoyance is noise. At times what is music for some can be noise for others. Most of the machines that have been developed for industrial purposes, for high speed transportation, or to make life more enjoyable, by furnishing additional comfort, reducing the drudgery of everyday living, and speeding up our daily routines to provide additional leisure hours, are accompanied by noise.
Noise prevention and control is important as noise affects us in hearing, ability to communicate and behavior. Undoubtedly, lesser noise can make the environment friendlier and life becomes pleasant.
Noise pollution regulation and control rules, was enacted to take care of the depletion in the environment due to excessive noise. These are rules regarding the noise levels that should be maintained in certain areas. The noise pollution rules came up with a silence zone i. According to the noise pollution rules authorities could take action and initiate prosecution against people who do not follow the rules. After the commencement of these rules also one can see many cases where people just honk without any reason creating chaos on the road and other places which comes under the purview of silence zone.
These people while honking and using loudspeakers does not realize the difficulties that they cause to others and to themselves. One can even lose hearing; stress levels can go high and even mental instability. Honking unnecessarily while driving has become a trend these days and one can hear it very well at the traffic signals.
Broadly speaking, the noise pollution has two sources, i. The industrial source includes the noise from various industries and big machines working at a very high speed and high noise intensity. This type of noise can be augmented by narrow streets and tall buildings, which produce a canyon in which traffic noise reverberates. Construction noise sources include pneumatic hammers, air compressors, bulldozers, loaders, dump trucks and their back-up signals , and pavement breakers.
These interior noise sources have significant impacts on industrial workers, among whom noise- induced hearing loss is unfortunately common. In this case, internal building noise from plumbing, boilers, generators, air conditioners, and fans, can be audible and annoying.
Improperly insulated walls and ceilings can reveal the sound of-amplified music, voices, footfalls and noisy activities from neighboring units. External noise from emergency vehicles, traffic, refuse collection, and other city noises can be a problem for urban residents, especially when windows are open or insufficiently glazed. Measurement of Noise Pollution To measure noise, the average pressure level of the sound is measured for a particular amount of time by a weighting scale.
It also finds out the response of the auditory system. The noise is measured as decibels. Noise dosimeter can be worn by the person and works better than noise level meter1 Effects of Noise Pollution Noise is generally harmful and a serious health hazard.
It has far-reaching consequences and has many physical, physiological as well as psychological effects on human beings. Hearing Problems: The physical manifestation of noise pollution is the effect on hearing ability. Repeated exposure to noise may result in temporary or permanent shifting of the hearing threshold of a person depending upon the level and duration of exposure. The immediate and acute effect of noise pollution is impairment of hearing i. Any unwanted sound that our ears have not been built to filter can cause problems within the body.
Our ears can take in a certain range of sounds without getting damaged. Man made noises such as jackhammers, horns, machinery, airplanes and even vehicles can be too loud for our hearing range. Constant exposure to loud levels of noise can easily result in the damage of our ear drums and loss of hearing.
Cardiovascular Issues: Blood pressure levels, cardio-vascular disease and stress related heart problems are on the rise. Studies suggest that high intensity noise causes high blood pressure and increases heart beat rate as it disrupts the normal blood flow. Bringing them to a manageable level depends on our understanding noise pollution and how we tackle it.
Health Issues: Excessive noise pollution in working areas such as offices, construction sites, bars and even in our homes can influence psychological health. These in turn can cause more severe and chronic health issues later in life. Sleeping Disorders: Loud noise can certainly hamper your sleeping pattern and may lead to irritation and uncomfortable situations. Without a good night sleep, it may lead to problems related to fatigue and your performance may go down in office as well as at home.
It is therefore recommended to take a sound sleep to give your body proper rest. Trouble Communicating: High decibel noise can put trouble and may not allow two people to communicate freely. This may lead to misunderstanding and you may get difficult understanding the other person.
Constant sharp noise can give you severe headache and disturb your emotional balance. The psychological manifestations of noise pollution are:3 a Depression and fatigue which considerably reduces the efficiency of a person. So, noise is annoying and the annoyance depends on many factors not merely the intensity of the sound but also repetition, because even a sound of small intensity e. Table 1. Effect on Wildlife6: Wildlife faces far more problems than humans because noise pollution since they are more dependent on sound.
Animals develop a better sense of hearing than us since their survival depends on it. The ill effects of excessive noise begin at home. Pets react more aggressively in households where there is constant noise. They become disoriented more easily and face many behavioral problems.
In nature, animals may suffer from hearing loss, which makes them easy pray and leads to dwindling populations. Others become inefficient at hunting, disturbing the balance of the eco-system. The measurements provide data on the ambient air quality but the contribution of individual sources is difficult to assess. Here, air quality models can play an important role. They come with the different equipment that includes generators, grinding mills, and compressors that create lots of noise pollution.
Also Read: Non technical topics. The human mind and body are affected negatively by the noise pollution. Look at the main noise pollution effects that we have mentioned below:. The risk of cardiac disturbance that includes ischemic heart disease or coronary artery disease has increased due to this type of pollution.
Noise pollution has become the main reason of the noise above the tolerable threshold. It has affected a greater portion of the population around the world. The maintenance of blood pressure is mandatory for good health and higher levels of noise results in increasing or decreasing the blood pressure levels that can affect the health badly.
The amount of stress is often increased by the loud noises. Moreover, the level of tensions also increases due to constant exposure to irritating noise. The noise pollution makes people tired and restless that can disrupt their sleeping pattern of the people. Vidya VOL. Sagar 48, 47, and No. The AAQNL were alarming even in the absence of conveyor system, indicating the impact of vehicular traffic. Remedial measures were suggested separately for each situation.
Introduction community's collective feelings about environmental pollution. This represents a degradation of health in accordance with the The basic hearing mechanism of the ear cochlea is the WHO's definition of health meaning - total physical and mental communication of sounds to brain by the small hair cells. A WHO Intense sounds damage these cells, some times beyond working group stated9, that noise must be recognised as a major recovery due to prolonged exposure to sounds1. Exposure to threat to human well-being.
Noise pollution can levels in residential, commercial and industrial areas, and silent play havoc with the nervous system affecting the physical zones of Delhi and other cities far exceeded the standards and psychological behavior of the individuals. The nausea, vomiting, pain, hypertension, high blood pressure, average noise level in Delhi is 80dB, which is more than the cardiovascular problems, sleep disturbance, restlessness, recommended value, i.
A general survey carried out in depression, fatigue, allergy, mental stress and annoyance3. There exists a connection between noise exposure and increased levels of catecholamines 4 and magnesium Visakhapatnam City in Andhra Pradesh India is one of metabolism5. These findings suggest a possible mechanism the ancient cities in India and has natural harbours that were for cardiovascular effects in that a chronic magnesium operated even in ancient times.
The city is well protected by imbalance can lead to increased intra cellular levels of calcium, Western Ghats. Due to the harbours, pure water sources, which in turn, can cause vasoconstriction and increase the availability of minerals, jute etc. Hence, ambient air quality A widely used method for recording the variations in noise levels AAQNL were monitored11 at selected sites. Noise levels were respect of silent zone.
Lavg values were fluctuating between dBA. At night time, Lavg persons, well isolated from the surroundings with open land values between to hours reached 22 dBA for short on all sides, but boundary walls surrounded by road with auto- durations. The levels of LN90 values were found in between rickshaw stands and with moderate bus and truck traffic.
It dBA, 5 dBA higher than the silent zone standards. Lmax has units for physiotherapy, treatment of hearing impairment, was in between dBA and Lpeak attenuated dBA. The study in night time Fig 2 results in higher noise annoyance. Vidya Sagar and G. It is a secured place for conducting noise-monitoring activity at beach front.
