A source told the Guardian that Hilary Benn, the environment secretary, had achieved concessions on air and noise pollution levels towards the end of last week, but Miliband's concerns were unresolved until overnight on Tuesday.

Noise pollution doubled sound levels in 12 % of all wilderness areas.

Noise pollution from humans has doubled sound levels in more than half of all protected areas in the United States — from local nature reserves to national parks — and it has made some places 10 times louder, according to a new study.

Pam Factor - Litvak, an epidemiologist at Columbia University not involved in the study, notes that it's possible the associations between fracking and poor infant health could be due to other factors besides pollution, such as extreme levels of maternal stress, perhaps due to noise and continuous traffic to and from the sites.

Changes in that signature can indicate how an environmental threat — such as the gradual effects of climate change or increasing levels of human noise pollution — disrupt animal communities.

And they built a sound model... so to get at an idea of noise pollution, we used two thresholds: where anthropogenic noise raises sound levels three and 10 decibels above natural.»

Researchers found that noise pollution was twice as high as background sound levels in a majority of U.S. protected areas, and caused a ten-fold or greater increase in noise pollution in 21 percent of protected areas.

High levels of noise pollution were also found in critical habitat for endangered species, namely in endangered plant and insect habitats.

Urban environments differ from natural habitats in many regards and are for instance associated with higher levels of anthropogenic pollution, such as traffic noise, artificial light pollution and air pollution, which enhance oxidative stress and inflammatory responses.

The results summarized predictions of existing sound levels, estimates of natural sound levels, and the amount that anthropogenic noise raises levels above natural levels, which is considered noise pollution.

Thanks to this high level of pre-production and the fast assembly site, the pollution of the environment could also be minimized by reducing noise, dust and exhaust gases.»

I accept that noise at a level that could cause physical harm would constitute «pollution» but given that wind turbine noise is more of a small background hum at distance of about 400m, that falls far short of a reasonable threshhold for measurable harm.

Rachel Buxton, a post-doctoral researcher at Colorado State University's Warner College of Natural Resources and lead author of the study, led a team of researchers that recorded sounds at 492 sites across the country in order to quantify the extent of noise pollution in the U.S. Using baseline sound levels for each study area established by machine learning algorithms that took into account geospatial features of the area, the researchers determined that anthropogenic noise pollution exceeds three decibels (dB), essentially doubling background sound levels, in 63 percent of the nation's protected areas.

After six years of research, demonstration airplanes use half the fuel, produce 75 % less pollution and are much quieter — noise is just one - eighth of today's levels, says NASA's Environmentally Responsible Aviation team.

Environmental quality standards for air, water and soil pollution as well as noise were defined as «the desirable levels that will maintain protection of human health and our living environment.»

In less than two minutes, the HEPA filtration system had scrubbed the air in the Passivhaus, bringing pollution levels from an extremely dangerous 1,000 µg / m3 to levels so low as to be undetectable (below the noise floor) by the instruments, allowing the test scientists to remove their gas masks and breathe fresh air while sitting inside a biome full of pollution.

Identified adverse effects of OSW include elevated noise and vibration levels, collision risk, habitat and food chain alteration, modification of natural sediment transport and deposition processes, and pollution generated by OSW construction, operations, maintenance, or decommissioning (Kaldellis et al. 2016).

The errors in the predicted sound levels can easily result in inadequate setback distances thus exposing the property owner to noise pollution and potential health risks.

High levels of public transport density are usually accompanied by higher levels of traffic - related noise and air pollution, especially in urban environments typified by a concentration of tall buildings.54 Both excessive traffic - related noise and air pollution have been linked to stress, inability to psychologically restore and depression.55 56 One of the main features included in the measure of street connectivity used in this study was the presence of bridges, overpasses or tunnels.
