This presentation on noise pollution covers the causes, effects, and facts related to noise and presents the ways to protect the environment from the harmful effects of noise in world and it also includes the statistics of Pakistan.
A sound, especially one that is loud or unpleasant or that causes disturbance.
Noise pollution is the disturbing noise with harmful impact on the activity of human or animal life. The source of outdoor noise worldwide is mainly caused by machines, transportation systems, motor
vehicles engines and trains. Outdoor noise is summarized by the word environmental noise. Poor urban planning may give rise to noise pollution, side-by-side industrial and residential buildings can result in noise pollution in the residential areas.Â
Sound becomes unwanted when it either interferes with normal activities such as sleep, conversation, or disrupts or diminishes one's quality of life.
Noise pollution affects both health and behavior. Unwanted sound (noise) can damage psychological health. Noise pollution can cause hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, and other harmful effects.
Chronic exposure to noise may cause noise-induced hearing loss.
overview of the ways that acoustic monitoring is being used by researchers and agencies to asses populations, guide policy, and monitor effects of human noise on wildlife
Noise pollution can negatively impact human health and the environment in several ways. It is defined as unwanted and disturbing sounds that disrupt normal activities or cause harm. Common sources include vehicles, construction, and industrial operations. Effects range from temporary hearing loss and sleep disruption to long-term cardiovascular problems. Reducing noise pollution involves determining its source, modifying machines to lessen sound levels, using protective equipment, and installing sound barriers when needed. Personal solutions include earplugs and noise-canceling headphones.
1) Noise pollution can be defined as any disturbing or unwanted noise that interferes or harms humans or wildlife. Sources of noise pollution include road traffic, aircraft, railroads, industries, loud speakers, and firecrackers.
2) The textile industry is a major source of noise pollution. Noise levels are highest at ring spinning machines and lowest at blow rooms. As loom and spinning machine speeds increase, noise levels also increase significantly.
3) Noise pollution has negative effects on public health like hearing loss, cardiovascular issues, and sleep disturbances. It also affects wildlife behavior and communication. Reducing noise at its source and increasing green coverage are ways to reduce noise pollution.
Noise pollution comes from both transportation and human sources and can negatively impact both human and animal health. Unwanted sounds become noise pollution when they unreasonably disturb daily life through distraction, sleep disruption, and inability to control the source of the sound. Noise pollution is measured in decibels and common sources include traffic, construction, aircraft, loud machinery, and barking dogs. Prolonged exposure to noise above 85dB can cause hearing loss and other health issues like high blood pressure and mental health problems. Wildlife are also affected through hearing damage, inability to communicate, and changes in behavior and reproduction. Regulations aim to limit noise during certain hours and require mitigation efforts to reduce impacts.
This document discusses noise pollution, including its definition, sources, measurement, impacts, and control methods. It defines noise pollution as unwanted sound that disrupts human or animal activity. The main sources discussed are road traffic, aircraft, railroads, construction sites, and industrial facilities. Noise is measured in decibels, and sounds above 80 dB are considered potentially hazardous. Health impacts from noise pollution include hearing loss, lack of concentration, stress, and sleep disruption. The document recommends various engineering and administrative controls to mitigate noise pollution from sources and protect receivers.
Noise pollution occurs when unwanted sounds disrupt normal activities or exceed levels that can damage human health. Major sources of noise pollution include transportation systems, construction sites, and industrial operations. Exposure to loud noises can cause health issues like high blood pressure, hearing loss, and sleep disruption. To reduce noise pollution, barriers can be placed around loud sources, regulations can limit vehicle noise, and public education on the issue is needed.
Noise pollution can negatively impact human health and quality of life. Unwanted sound that is loud or persistent enough can damage hearing or cause annoyance. Common sources of noise pollution include transportation like vehicles, aircraft, and trains, as well as industrial operations, construction, and recreational activities. The ear converts sound vibrations into nerve signals that are perceived by the brain as sound. Noise is measured in units called decibels and standards aim to limit exposure and emissions from various sources.
TOWARDS A QUIETER FUTURE: NOISE POLLUTION PRESPECTIVES AND IT SLEGAL IMPLCATIONSPrashant Mehta
Â
The document discusses noise pollution, its causes and effects. It notes that noise pollution is an unwanted sound that can negatively impact people's health by causing hearing loss, increasing blood pressure and heart rate, and interfering with sleep. Common sources of noise pollution are identified as traffic, construction equipment, loud music, and barking dogs. The document advocates for stronger legal regulations and enforcement to help control noise pollution and protect public health.
Urban areas experience higher noise pollution than rural areas due to transportation, industrial, and residential sources. Transportation is a major contributor, including vehicles, motorcycles, and aircraft. Factories and machinery also produce industrial noise. Residential appliances and activities add to noise levels. Prolonged exposure to loud noises can negatively impact both physical and mental health, causing issues like hearing loss, stress, and sleep disturbances. Reducing and controlling noise requires efforts like better building insulation, regulating horn usage and loud vehicles/machines, placing industries and airports away from communities, and preserving green spaces to absorb sound.
This document provides information on different types of pollution including air, water, noise, soil, and solid waste pollution. It discusses the causes, effects, and methods of prevention and control for each type of pollution. For air pollution, it outlines sources of primary and secondary pollutants and their health impacts. For water pollution, it examines various forms like marine, thermal, nutrient, and biological pollution and their effects. The document also looks at noise pollution levels and regulations in different countries. Finally, it analyzes the risks of poor solid waste management and the functional elements of solid waste systems.
The document discusses noise pollution, defining it as unwanted or disruptive sound that negatively impacts human or animal life. It notes that while sound and noise are physically indistinct, noise is sound perceived as unpleasant, unwanted or disruptive. Major sources of noise pollution are listed as road traffic, construction, aircraft, railroads and consumer products. The effects of noise pollution on humans include hearing impairment, decreased work efficiency, lack of concentration, stress, heart issues, and sleep interference. Solutions proposed are better soundproofing, limiting loud machinery near homes, and growing plants that absorb sound. The key message is that excessive noise poses risks and mitigation efforts are needed.

The more recent annual reports, also available here on SlideShare, are much more current and reflect a broader, deeper understanding of the complexities and subtleties of the issue. While this 2009 review is a decent introduction, the subsequent reports also stand no their own, and do not need this foundation. PLEASE do not rely solely on this report!!
A comprehensive and thoughtful overview of the current state of the wind farm noise controversy, centered on 10 pages of summaries of new research published in 2009.
1) A report by the American Wind Energy Association and Canadian Wind Energy Association concludes there are no health effects from wind turbine noise but omits discussion of sleep disruption, which is the most widely reported impact.
2) The report minimizes reports of annoyance from wind turbine noise and selectively interprets studies in a way that keeps annoyance rates below 10%.
3) While the report challenges theories linking low frequency wind turbine noise to health issues, it fails to address studies finding vibration and resonance in nearby homes from wind turbines.
This document provides a summary of key developments regarding ocean noise science and regulation in 2007. Some highlights include the Marine Mammal Commission's report on managing ocean noise which called for improved research coordination and regulation of unmanaged noise sources. Research using DTAGs provided new insights into how moderate noise levels can disrupt whale foraging and behavior. Issues around Navy sonar use and its impacts on whales continued to be litigated. Chronic exposure to moderate noise levels was recognized as a growing concern, with studies finding it can damage whale hearing and alter behavior. Shipping noise was a major focus, with research exploring how it dominates ambient noise over large areas and efforts toward developing quieter ship designs and operations. Whale watching and recreational boating noise
The document discusses key developments in 2006 related to understanding the impacts of ocean noise on marine life. It highlights that chronic exposure to moderate noise levels, such as from shipping traffic, is increasingly recognized as a major threat due to its potential to cause masking of communication and navigation calls for marine animals as well as increased stress levels. Several studies in 2006 provided new evidence on the physiological and behavioral impacts of moderate noise from sources like boats and pile driving. These subtle impacts could accumulate over the long term to significantly disrupt populations, though more research is still needed on cumulative and population-level effects.
This document provides a 3-page summary of the 2008 Acoustic Ecology Institute Special Report on ocean noise. It discusses four key developments in ocean noise issues that year: 1) Behavioral impacts replacing strandings as the primary concern regarding marine mammals and noise, 2) Continued legal issues around naval sonar but focus shifting to behavioral impacts, 3) Shipping noise becoming a major international concern, and 4) Scientific community entering a new phase of engagement around organizing ocean noise research priorities. The summary examines these developments and provides context and examples from research studies reported on in the full AEI Special Report.
Scientific Uncertainty, Evolving Management, and the Emergence of an Ethics o...Acoustic Ecology Institute

An overview of the ways that science, regulators, and public pressure have interacted to move gradually toward more consideration of the impacts of human sounds on wild habitats
Moderate anthropogenic noise may disrupt foraging activity in whales and dolphins. Recent research has shown subtle behavioral responses to moderate noise levels, including interruptions to foraging. Repeated observations have found decreased foraging and animals remaining near the surface in response to activities like seismic airgun surveys, sonar, and boat noise. Foraging disruptions are a concern as they could negatively impact long-term individual and population health by reducing energy intake. More research is needed to better understand impacts, especially given inconsistent propagation patterns and variable responses observed between individuals and species. Systemic approaches that consider different levels of response across noise levels may provide a precautionary way to assess impacts until knowledge gaps are addressed.

"$10 thousand per minute of downtime: architecture, queues, streaming and fin...Fwdays
Â
Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

Editor's Notes
Hi everyone. As usual in these settings, my presentation is less practical than most here; Iâm usually asked to bring in some sort of big picture view. Either that or itâs just for comic relief from the non-profit dream world, I never really knowâŚ. This year, Iâm going to be addressing what appear to me to be inevitable dynamics that lead to the fact that no matter how well we meet standards asked of us, weâll always be asked to do more.
GET THIS DOWN!!!!!!!!! ITâS EASY!!!!!!!!!!!!!!!!!! Directive 38 is a stellar noise control standardâŚâŚyet history, and current events both here and elsewhere, tells us that both public pressure and improving technologies will tend to push a continuing evolution of noise standards toward reducing our acoustic footprint.
Quite naturally, as energy development continues to move into areas closer to human habitation and deeper into wild places, conflicts are on the increase. The industrialization of landscapes and the introduction of noise sources that are louder or more constant than residents are used to, can serve as a trigger point, a specific irritant, that leads to increased complaints.
My message today is that no matter how diligently we work to meet the current standards, there will always be pressure to reduce impacts even more. Weâll look at LESSONS ETHICAL PATH
Environmental regs often move gradually along a continuum from, to put it coarsely, a kind of free-for-all, into increasingly strict regulatory burdons.
Next comeâŚ..
Leads to an era ofâŚ
Here we see Navy sonar techs, whale researchers, and the beleaguered head of the NOAA ocean acoustics program, who âs got the Navy, researchers, and the public equally upset
In forestry, recreation, wildlife conservation, and alternative energy, environmental regulation is forever tightened.
Letâs look at some examples of how scrutiny of industrial activities inevitably increases over time--no matter how well we respond to the requirements imposed.
In forestry, the evolution is easy to seeâŚ..
Then, in 70s and sinceâŚ
Now, more and more clarity, yet comes with more limits on many activities, both industrial and recreational
Current state of the art isâŚ..
Impacts on wildlife are diverse, and recent years has seen increasing scrutiny of the effects of noise in parks and around industrial developments
Ocean noise has stirred a lot of public awareness, and is a great example of how it started as a sort of âout of sight out of mindâ free-for-all in which noise impacts were totally off the radar
5-10 years agoâŚ..2000 BahamasâŚ. started a surge of concern among scientists, navy and the public about intense sound injuring and killing whales.
In just the past 2-3 of years, major shift toward very broad-based concern over behavioral impactsâŚ..
In just the past 2-3 of years, major shift toward very broad-based concern over behavioral impactsâŚ..
And now, MPA managers and sonar activists are starting to talk about STRs based on need for natural acoustic habitat
On land, too, new and more specific questions are being asked by scientists and regulatorsâŚ.
NPS is doing fascinating research into the effects of moderate background noise on animals who need to listen at the edges of audibility. This could be relevant near CBM compressors and in the north woods oil sands regions.
A whole array of different sorts of impacts of human noise have become common considerations in the research and regulatory communities.
And itâs not just wildlife impacts that led to increasing regulationâŚ.
IN all these arenas--the ocean, among animals, and in human communities--the push for increasing regulation has an unspoken ethical dimension underlying the discussion.
Why do we live in the wide-open west?
Why do we live in the wide-open west?
Why do we live in the wide-open west? Of course, in the early days, the soundscape was dominated by the winds, the weather, the birds, along with livestock moving about, chewing and calling, and the nearly organic sounds of creaking cartwheels and steel plows churning through the soil. A couple of recollections of those soundcapes: Saskatchewan novelist WO Mitchell: âHis ears were filled with the sound of the wind, singing fierce and lost and lonely, rising and rising again, shearing high and higher still, singing vibrance in a void, forever and forever wildâŚâ CA Kenaston, though, in The Great Plains of Canada, addressed the windless times: âWhen, also, nature is undisturbed in tranquil summer mood, and the sky is blue and flecked with fleecy clouds floating far aloft, all sound seems to have died out of the world, and the mantle of silence enfolds everything. Partaking of the predominant natural sentiment, man becomes silent, also; he ceases to talk to his mates and becomes moody and taciturn.â ======= had quite a different experience of powerful prairie winds, which he said were âcomparatively inaudible, for there are no waters to dash, no forests to roar, no surfaces to resound, while the short grasses give forth no perceptible rustle, and there is something awful in the titanic rush of contending natural forces which you can feel, but cannot see or hear. The wind may sweep away your breath on a current of sixty miles an hour, and the clouds may rush through the sky as in a tornado, but no sounds confound the earâŚâŚ
During the twentieth century, the work life of ranching and farming families began to include more and more motors. Daily life involved increasingly more immersion in the sounds of engines. Ploughing, harvesting, feeding, and going to town all took place within a new cocoon of noise. This noise, however, was by and large easily accepted. While some may have resented the new intrusions, and perhaps would have chuckled in recognition when Murray Schafer said, much later, that âthe best I can say of the automobile is that the sound it resembles most is the fart,â for the vast majority of rural residents, the benefits in labor saved made the sound of these new machines music to their ears.
At the same time, these new vehicles moved from the farmyard and ranch headquarters and began to join horses and wagons on the roadways between remote farms and ranches and local town centers Still, when a vehicle passed by, even if it was not related to the farm or ranch itself, it was likely a friend or neighbor going about their very similar business, so that the noise intrusion had a content, a context that was still part of the individualâs experience and the life of the community. Indeed, in the middle years of the last century, a farmer would be likely to pause and watch the passing of a truck on the road; more likely than not, it would slow and a chance to catch up with a neighbor would be at hand. Before long, the sounds of mechanization were travelling along a network of roads and railways that pierced the quiet distances between settlements. Gradually, rural residents began to experience the âintrusionâ of outside noise, not related to their own or their neighborâs work; still, though, the traffic that moved between settlements was largely serving the needs of the communities: bringing in supplies, taking out local products. Only in the last generation have the highways become such long-distance thoroughfares that their noise approaches something close to constant, with most passing traffic having little direct relation to the community. Think for a moment of how this is a different experience; the âoutside worldâ buzzing in the background, or even foreground, of what used to be a remote, insular place.
I do believe that the key thing is that is different is that much of the noise is no longer related to the daily lives of residents. Work crews show up in what they consider to be âtheirâ fields, and though they pass through, it is a radical divergence to simply have anything going on out there that is not under the direction of the rancher and his family. Truck traffic through towns plays into this: we canât avoid the fact that big trucks with jake brakes create an entirely different sonic presence than farm trucks, one that can far more easily penetrate the walls of a house and become an nuisance or even a physical impact with its vibrations. While establishing patterns of truck traffic could be difficult or even impossible, itâs crucial to recognize that it IS a significant change, and one with negative consequences.
Certainly the relentless quality of some noise, especially compressor stations, is an entirely new dimension of experience.
The experience that people have of their home places can not always be adequately accounted for by dispassionate numbers. If you were in this place, at the time this picture was taken, Iâm quite sure that a 38dB CBM compressor would feel rather invasive.
By and large, the people who have spoken up about the noise impacts of oil and gas development are folks with long family histories on the land, people who generally live and let live. When such people decide that they need to say something, it usually bears listening to.
Discomfort can build, as the very core of oneâs reason for choosing the life one has is challenged by the changes in the landscape. Quote is from Peter Lauridson.
Fiona Lauridsen was taken aback by the changes to her experience after CBM wells began filling the prairie around her home: â I donât have all the city amenities, but I had quiet, space, and peace. Now I donât have that.â
⌠.and I also want to suggest that what YOU consider an insignificant or acceptable sound, someone else (especially someone who lives with it), may experience very differently. Even if it falls within or under your threshold of acceptable noise, it may truly be an irritant. If it IS a sore spot for those living with it, whether humans, livestock, or wildlife, what is your responsibility? --to tell them itâs no big deal because the numbers look good? --to make them work it out with the company? --to try to reduce the noise to the best of your ability? --take this experience and incorporate new proactive policies to help assure others wonât repeat the experience? â Canât they leave ten square miles around Rosebud alone?,â said a local businesswoman, âWill natural gas be the only industry left in Alberta?â Even the EUB acknowledges, in a recent annual report that Alberta faces âsome interesting, almost contradictory challengesâ XXXXXX
Most of you have probably considered lists like this in the course of your work with communitiesâŚ..
A key in any conflict is to zero in on values that are shared by everyone. I am going to keep pounding these two key values, ones I know we all believe in: Respect and consideration. From this foundation, we can fulfill our desire to care for the land and for the social bonds of those who live here, WHILE making use of what the landscape offers us, including energy resources A big part of this is accepting and working with the fact that a given sound will have a different effect in different places, and on different people. This is a place where it can be important to see the framework of models and dB threshold levels could be used as a starting point, rather than The Final Word. If we can look past these concrete frameworks, we can give more authentic consideration to what we hear from individuals and communities.
Always, itâs those who act above and beyond the letter of the law that lead the wayâŚ.
Is it âŚâŚ Practical, Feasible, Ethical? âŚ.. Is the leading edge, but, yes to eachâŚ..
The bottom line, really, is the measureless value of bringing a real sense of consideration and respect to local communities. Rather than doing all we can to get at the resource, why not do the very best we can to develop it in consort with the needs of those who live there? I have no doubt that the sentiments Iâm suggesting--respect and consideration--are ones that every one of you can appreciate, and that you do act with these same values in mind in your personal lives. What I am really asking of you, is that you bring these core values you hold as an individual, and redouble your efforts to find ways that these same values can be given expression within the structures of corporate planning and agency oversight.
What Iâm suggesting is to challenge yourselves to commit to moving beyond the practical goal of sustainable development and to tackle the more interactive idea of ethical development. What do I mean by ethical development? I think this approach would be based on empathy, and so involve more listening, to people and the landscape. And, on the ground, likely providing more space for wildlife, livestock, and people to live free of noise intrusions. (each of these pictures shows development that appears to be respecting the landscape around (though Iâm not privy to any specific environmental issues at these sites)âŚthese could all be examples of what Iâm calling ethical development More than analyzing numbers Doing more than âenoughâ It means letting go of having relatively unfettered access, just âbecause you can.â Proactively looking at the long term and the place of energy development in the community and the landscape. Most fundamentally, the idea of ethical development draws on the ancient concept of stewardship. Stewardship for the land, for wildlife, and for the communities that you are part of. Which comes back to my favorite concept today: actively giving consideration to the people you are working with and for. XXXXXX
Landscapes are integral wholes, bodies with many parts, all of which need to remain in relation and communication with each other. Within any habitat, a rich web of acoustic communication is taking place. Very often, animals need to be able to hear and be heard over long distances; it is common that the faintest calls are as important as nearby ones. A background hum of compressors or the sporadic intrusions of truck traffic can disrupt these subtle networks of communication. This is not to say that development should not take place; rather, that there are many biological and historical reasons that we may want to be sure to respect the landscapes enough to leave large patches relatively untouched.
Redoubling efforts to complete comprehensive planning Finally, the underlying imperative: to leave the landscape as a whole with a thriving integrity when the current development boom is over, whether thatâs in fifteen years, fifty years, or more. Certainly, there will be areas that are temporarily sacrificed for energy development. Some of these areas may regenerate after ten years, some may take generations, and some, like taiga stripped away by oils sands projects, may never return. But in every case, for every landscape in Alberta, it is altogether possible to retain areas that will serve as sources of regenerative vitality in the future.
