Maps show noise impact of Heathrow runways

Maps show noise impact of Heathrow runways

PEACE and quiet in north-west Surrey could be drowned out forever if Heathrow Airport is allowed to develop into a four-runway hub, according to new research by an anti-expansion group.

The 2M Group, led by the Conservative-controlled London Borough of Wandsworth, is an all-party alliance of more than 20 local authorities concerned about the environmental impact of Heathrow expansion on their communities.

The group, of which Spelthorne Borough Council used to be a member until switching allegiance and backing the airport, has produced noise contour maps showing areas that could be affected by aircraft from a four-runway Heathrow.

It is already feared that tens of thousands of residents in Spelthorne could be forced to move from their homes to make way for the expansion.

The maps are colour-coded to show which areas would be most adversely affected by noise – with the towns and villages in darker shading bearing the greatest brunt.

According to the maps, there would be an increase in noise for Staines, Egham, Virginia Water and Thorpe, as well as what was left of Stanwell and Ashford, plus parts of Elmbridge.

Heathrow Association for the Control of Aircraft Noise (HACAN) chairman, John Stewart, described youtubemp3now.com the impact of two additional runways as “devastating”.

He said: “The opposition from 2M and residents would be so great that it probably makes the whole project politically impossible.”

The 2M Group has consistently warned that Heathrow will not stop expanding if granted a third landing strip.

A spokesman for the airport said: “We are currently examining a number of options, all of which result in significantly less noise for local residents than the 2M Group’s scaremongering.

“We know aircraft noise can disturb people living under the flight path, which is why we encourage airlines to fly only their quietest aircraft at Heathrow through higher charges for noisier aircraft.”

The airport’s main European rivals have four or more runways and Heathrow will need to match their capacity to directly compete.

Charles de Gaulle Airport in Paris already has four runways. Frankfurt and Barajas (Madrid) also have four, while Schiphol (Amsterdam) has six.

Beijing pilots illegal-honking detectors

Drivers who indiscriminately use their car horns in future could find themselves being booked thanks to a system of detectors being installed along the Chinese capital’s key areas by the Beijing Traffic Management Bureau, according to Beijing Youth Daily.

“The detectors consist of three parts, namely, a microphone array acquisition device, an electronic capture and a LED prompt system. Combining the three systems, we can distinguish between the sounds of horns, brakes and engine noise, etc.,” said Li Jianfeng, deputy director of the Scientific and Technical Information Department of the bureau.

“The detectors can accurately collect honks.” Li said. “Even parallel vehicles can also be identified based on their position in each lane; the recognition locator feature can reflect the direction the honks are coming from, so there will be no misjudgment.”

The system photographs the number plate of the offending vehicle so that the driver can be tracked down and prosecuted.

Honking horns have long been an irritating contributor to Beijing’s noise pollution levels.

According to The Measures of Beijing on the Implementation of the Law of the People’s Republic of China on Road Traffic Safety, violation of the provisions in regard to indiscriminate honking will incur a fine of 100 yuan (US$14.76).

The cities with the worst noise pollution

When you think about pollution you probably imagine a smog-filled city, or an ocean choking on plastic.

But pollution extends beyond what’s in the air and the water. Noise pollution, the noise we live with every day, is a growing problem, and it’s affecting our hearing.

Unsurprisingly, noise pollution is particularly bad in cities. A recent study found that Guangzhou in China had the worst noise pollution, while Zurich in Switzerland had the least.

The Worldwide Hearing Index was created by digital hearing app founders Mimi Hearing Technologies GmbH. They analysed the hearing test results of 200,000 of their users.

They combined their results with data on noise pollution from the World Health Organization (WHO) as well as from SINTEF, a Norwegian-based research organization, and used it to plot noise pollution in 50 different cities.

SE Asia is in the well represented with 9 cities in the worst top 20, lot’s to improve !

Typical sources of noise pollution are transport, such as road, rail and air traffic, construction and industry, and radios and televisions blaring in shops, restaurants and bars.

World Hearing Day 2018

Millions of teenagers and young adults are at risk of developing hearing loss due to the unsafe use of personal audio devices such as smartphones and MP3 players and exposure to damaging levels
of sound at noisy entertainment venues including nightclubs, discotheques, bars, pubs and sporting
events. The emerging pattern of listening regularly at high volume and for a long duration poses a serious
threat to one’s hearing. Hearing is a precious faculty, which impacts educational, professional and social
development.
Noise-induced hearing loss can be prevented

Taiwan: Airport MRT trial run smooth, despite noise concerns

Airport MRT trial run smooth, despite noise concerns

Taipei, Feb. 7 (CNA) The Taiwan Taoyuan International Airport Mass Rapid Transit (MRT) line has been running smoothly since it started trial runs Feb. 2, although there have been noise concerns in one of the neighborhoods through which it passes, the authority that oversees the line’s construction said Tuesday.

The system has been stable as of Feb. 6, the Bureau of High Speed Rail said, adding that the line has carried 34,000 passengers during the five-day period.

There remain some minor bugs in the system, such as signal displays and early checked-in luggage processing, but they are expected to be fixed before the line’s commercial operations begin March 2, the bureau said.

However, more evaluation is required about the noise problem in a New Taipei neighborhood, said bureau Deputy Chief Engineer Jao Kuo-cheng (饒國政).

“We have already installed acoustic walls, but they do not seem to be effective,” he said.

According to the local environment agency, the line is generating around 75 decibels of noise in the area in question, slightly below the maximum limit of 85 decibels but enough to cause complaints from local residents, especially during late hours.

Jao said the bureau will look into the problem and draft a plan in two months to improve the situation.
