Heart attacks more likely where traffic is louder

By Susan E. Matthews, MyHealthNewsDaily, June 2012

The louder the traffic near people's homes, the greater their risk of heart attack, a new study from Denmark says. The researchers tracked more than 50,000 study participants for nearly 10 years and found that for every 10 decibels of added roadway traffic noise, the risk of heart attack increased 12 percent.

“Anytime you’ve been exposed to high levels of noise, you have increased concentrations of stress hormones in your body, which could explain the increased heart attack risk,” lead researcher Mette Sorenson said.

Sorenson and her fellow researchers found that the link between heart attacks and roadways held even after accounting for the heightened levels of air pollution near roadways. They estimated that four percent of all heart attacks in Denmark are related to traffic noise. The real danger with noise pollution is that most people

don’t realize they are experiencing it, Sorenson said.

For the study, the researchers asked participants to report where they lived and whether they had ever had a heart attack, along with other information, including their diets and physical activity habits. The participants’ addresses were used to assess the noise they experienced. The re-searchers also accounted for factors that could affect participants' risk of heart attack, including gender, smoking, fruit and vegetable intake, and body mass index.

While the link between noise pollution and heart attack risk has been shown before, the new study is one of the first to demonstrate an incremental correlation between increasing noise and increasing risk. Previous studies have shown that risk increased at noise levels above 60 decibels; this study showed that risk increased between 40 and 80 decibels. The study was published June 20, 2012, in the journal PLoS ONE.


Ban on crowing for dawn chorus rooster

A rowdy rooster which wakes the neighbourhood in the middle of the night has been issued with a noise abatement notice. Environmental health officials were forced to act after scores of complaints about Rodney’s deafening dawn chorus, which starts as early as 3:43 a.m. He has been heard to cry an earsplitting “cock-a-doodle-doo” 26 times in just 16 minutes. His owners have now been ordered to silence Rodney or go to court and face a £5,000 fine.

Bath and North East Somerset Council officers set up re-cording devices in nearby homes in Weston, Bath, and were staggered by what they heard. His shrieks reached 60 decibels - double the limit the World Health Organisation considers acceptable background noise at night.

Last week, owners Matt and Kerrie Summers said they would rather sell up and move than get rid of Rodney. Mat, 39, said: “It’s an overreaction, I think it is ridiculous. There are donkeys, cows and sheep on the nearby farm but no one has said anything about that.” But teacher Richard Garforth, 65, said: “We have been woken up for six months as early as 4 a.m., which has been very difficult. We are in a residential area, although we do have a farm close by. They don’t make noise at 4 a.m. It has upset us during the day too. Sometimes we have had to close all the windows.”

Smartphone goes out the window

Because a drunk woman spoke too loudly on a Hamburg "S-Bahn" train, a 46-year-old man threw her Smartphone out of the moving train. Allegedly, the man was so disturbed that he grabbed the 700-Euro gadget and threw it out the window, federal police informed. The man immediately confessed to his deed when officers arrived at the scene.

According to statements of the federal police, other passengers had already complained about the loud talking of the drunk 23-year-old woman prior to that incidence. When she didn't respond, the 46-year-old acted in self-defence. Legal action was initiated against him. Federal police officers searched for the Smartphone along the train tracks in vain. On account of that, four trains were running late.

Noise in 95 metres height

Police report: droning construction crane deprives Darmstadt residents of their good night’s sleep. Even during the daytime, noise from the cranes at the construction site of the new students’ living quarters next to the highschool stadium does not go unnoticed. Finally, they triggered action by police and fire department. Suddenly there was a loud rumbling lasting for 45 minutes. That prompted numerous residents to reach for the telephone after 10 p.m. and call police and fire department. They described the sound like loud sawing or a defect aircraft turbine, reported

police spokesman Ferdinand Derigs.

Because the efforts of police to find a company responsible for the site were in vain, the professional fire fighters had to spring into action. They identified “an electrical box 95 metres up as the source of the noise”. To restore quiet, they simply shut off the power. For that, one female resident expressly thanked the police. “Praise for the police,” Derigs said with joy.
