Officials at the Environmental Protection Administration (EPA) are planning to adopt a noise-mapping system that will allow them to identify locations with the highest decibel readings and help them determine sources of noise pollution.
Lin I-chun (林怡君), an EPA senior environmental specialist, confirmed yesterday that the administration has begun to test operations of such a system in the Zhongshan (中山), Songshan (松山) and Neihu (內湖) districts in Taipei.
The area covers north of Nan-jing E Road, south of Dazhi Street and Wende Road, east of Fuxing N Road and west of Tiding Avenue.
Lin said the EPA uses statistics collected through the surveillance devices installed in these areas and inputs them into the system. Road sections showing high decibel readings appear on the noise map in darker colors (purple or red), whereas those with lower decibels are marked in lighter colors (yellow or green).
Analysts then compare the mapping results to find the major sources of noise pollution. For example, the noises in the aforementioned areas mainly come from two places -- Songshan Airport and the traffic on Sun Yat-sen Freeway and Tiding Expressway.
"We have yet to offer up-to-the-minute reports on decibel readings in certain locations, like what they do with air quality forecasts," she said, given the limited number of surveillance devices installed.
Lin added that the EPA would discuss possible options for the next test area tomorrow.
The EPA also said in a statement yesterday that it plans to integrate all the large metropolitan areas in the country into the noise-mapping system after it has solved all technical difficulties. The environmental protection bureaus in each county will then be able to take immediate action to control noise.
EPA statistics showed that noise pollution was the No. 1 source of complaints in recent years. Last year, the number of complaints over noise pollution reached 37,000, accounting for 31 percent of all the cases EPA handled.
FLU SEASON: Twenty-six severe cases were reported from Tuesday last week to Monday, including a seven-year-old girl diagnosed with influenza-associated encephalopathy Nearly 140,000 people sought medical assistance for diarrhea last week, the Centers for Disease Control (CDC) said on Tuesday. From April 7 to Saturday last week, 139,848 people sought medical help for diarrhea-related illness, a 15.7 percent increase from last week’s 120,868 reports, CDC Epidemic Intelligence Center Deputy Director Lee Chia-lin (李佳琳) said. The number of people who reported diarrhea-related illness last week was the fourth highest in the same time period over the past decade, Lee said. Over the past four weeks, 203 mass illness cases had been reported, nearly four times higher than the 54 cases documented in the same period
A group of Taiwanese-American and Tibetan-American students at Harvard University on Saturday disrupted Chinese Ambassador to the US Xie Feng’s (謝鋒) speech at the school, accusing him of being responsible for numerous human rights violations. Four students — two Taiwanese Americans and two from Tibet — held up banners inside a conference hall where Xie was delivering a speech at the opening ceremony of the Harvard Kennedy School China Conference 2024. In a video clip provided by the Coalition of Students Resisting the CCP (Chinese Communist Party), Taiwanese-American Cosette Wu (吳亭樺) and Tibetan-American Tsering Yangchen are seen holding banners that together read:
Heat advisories were in effect for nine administrative regions yesterday afternoon as warm southwesterly winds pushed temperatures above 38°C in parts of southern Taiwan, the Central Weather Administration (CWA) said. As of 3:30pm yesterday, Tainan’s Yujing District (玉井) had recorded the day’s highest temperature of 39.7°C, though the measurement will not be included in Taiwan’s official heat records since Yujing is an automatic rather than manually operated weather station, the CWA said. Highs recorded in other areas were 38.7°C in Kaohsiung’s Neimen District (內門), 38.2°C in Chiayi City and 38.1°C in Pingtung’s Sandimen Township (三地門), CWA data showed. The spell of scorching
UNAWARE: Many people sit for long hours every day and eat unhealthy foods, putting them at greater risk of developing one of the ‘three highs,’ an expert said More than 30 percent of adults aged 40 or older who underwent a government-funded health exam were unaware they had at least one of the “three highs” — high blood pressure, high blood lipids or high blood sugar, the Health Promotion Administration (HPA) said yesterday. Among adults aged 40 or older who said they did not have any of the “three highs” before taking the health exam, more than 30 percent were found to have at least one of them, Adult Preventive Health Examination Service data from 2022 showed. People with long-term medical conditions such as hypertension or diabetes usually do not
