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.

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.
