Pollution as we all know becoming one of the most dangerous threats to the environment and mother nature. This pollution comes in different ways as everything nowadays is polluted and causing harm ultimately to the earth. Soil pollution by the chemicals, air pollution by the vehicles and carbon dioxide emission, water pollution by discharging the harmful residues of the factories and household waste, another dangerous pollution type is noise pollution which seems so easy and not so big type but this also seems to create a lot of problems and diseases among people now.
World Health Organization says that One in five Europeans is regularly exposed to noise levels that could “significantly” damage their health. According to WHO now the environmental or noise pollution is becoming the top environmental risks to the health.
Dr. Dorota Jarosińska, who is the program manager for living and working environments at Europe says More than 100 million Europeans are affected by road traffic noise alone each year. “Noise continues to be a concern,”
Noise pollution or it is known as environmental noise, is the noise which has a harmful and dangerous impact on the humans and animals.
CAUSES OF NOISE POLLUTION
1. Main causes of this pollution is the noise caused by the machines which are engaged in the big factories
2. Transportation systems noise is also one of the causes
3. Loud music
4. Construction sites
Professor Stephen Stansfeld, who works in Barts and the Queen Mary University of London told The new guidelines are “an important update,” given the evidence and links to health problems.
The noise which is unbearable and contains harmful impacts can create the conditions which can become worse like Blood pressure or heart diseases which will further lead to the chances of heart attack and mortality ratio from heart disease will also increase.
In animals the noise pollution creates more adverse effects like their ability to detect the predator will be decreased, their reproduction pattern may be changed, or permanent hearing loss will be there. In adults, it causes cardiovascular diseases and the effects on children are also there which may be also dangerous and can result into the permanent effect
Jonathan Gale, a professor of cell biology and director of the UCL Ear Institute, wrote in an email that he “welcomes the new WHO guidelines as they bring the human impact of noise exposure to the fore.” New guidelines have been formed by the two expert groups who have reviewed the research and then deduced the results which will be acceptable noise levels for day and night.
Noise level included the noise created by the wind turbine, leisure noise, music in loud volume at pubs, disco. The guidelines which are made suggested that the noise levels should be below of 53 decibels of traffic and at night 43 decibels is recommended.
Stephen Turner, a president-elect of the Institute of Acoustics in the UK, believes that this reduction “can be achieved.”
“The challenge is, there are an awful lot of people affected. Whether we have the technology yet to be able to secure that reduction without having an adverse impact on travel and connectivity, I’m not sure,” he added.
Sound level of railways, aircraft have been also recommended in the guidelines as 44 dB to 54 dB. At night the sound coming from aircraft should be less than 40dB as higher sound will interfere with the sleeping pattern of the people and can create adverse effects also.
At the workplace, noise pollution can also induce hearing loss and other health-related issues. That is why the Occupational hearing loss is becoming the most common disease in the U.S. and other parts of the world. WHO discussed the guidelines.
Noise pollution have different aspects and it is very diverse also, every aspect has its own recognizable characters and consistency. Reports tells the loudness is also different. So the negative impact on health due to the loudness may vary on the scale of and type of noise pollution. But the new guidelines are based on reviewed evidence that noise exposure has risks of negative health outcomes. “The most frequent impacts are the annoyance and sleep disturbance,” Stansfeld said.
Gale noted, “Exposure to environmental noise can result in hearing loss that, in the longer term, can cause social isolation and [an] impact on health and well-being. Both the level and duration of the exposure are important factors.
“However we know much less about the effects of exposure to low levels of environmental noise over long periods,” he added. “We think such noise is unlikely to affect our sensory hair cells [in our ears] but may well effect our brain processes and possibly our mental health.”
The ultimate solution for this problem is that if we can reduce the exposure of human and animals of noise pollution then we will be able to fight againts the health problems troubling us from this. Turner said that the health effects, such as increased risk of heart attacks, manifest at “high exposure” of noise levels. “If we focus on reducing the high exposure [of noise pollution], we can reduce those adverse health risks.”
Many other control aspects are there like we can try to reduce the noise pollution caused by leisure and pubs, disco. The construction sites causing noise can be far away from the residential areas so that humans and animals will not become affected by the noise. Engineering noise controls can be used to reduce noise propagation and protect individuals from overexposure.
There are the situation which are unavoidable and you have to go to the places which are full of noises and that can surely harm you then the prevention measures should be taken. We can use plugs or ear muffs to cover our ear and which will help to protect us from dangerous effects and occupational noise exposures. Aircraft noises can also be reduced by using the engines which are more quieter and will not harm the people living nearby.
