Public facilities would be deaf ears
when they lose their functions to
serve the public. Eco-friendly noise information displays on several traffic mainstays in Shenyang are getting into such awkward position. Some citizens said they had 'fallen asleep for some years.'
The Commercial Times recently made a survey to five noise sensor screens in urban districts such as Heping, Dadong and Shenhe and found only one in Dongling District still works, while other four stop working or even disappeared.
It cannot be figured out when the four screens stopped working but it is known that the noise sensors were put in use six years ago.
Shenyang's environment protection authorities installed the three screens on traffic mainstays such as Qingnian Avenue and Heping Avenue in August 2006.
Compared with the one built in front of the city environment protection bureau, the new sensors were improved with wireless data transmission: they can convey nearby noise data back to environment watchdog once a 20 seconds and they environment protection authorities would record the data for analysis and offer solutions and warnings to local noise pollution areas.
A bigger part of noise information displays were produced by Shenyang Haozheng Tech Corporation, but the firm closed down long time ago.
"The devices, commonly referred to as noise information display, are actually environmental and traffic noise sensor in urban areas," a source surnamed Xu with a environment evaluation firm told reporter of the Commercial Times. "The portable devices we take to assess noises cost less than 10,000 yuan. But the noise sensor is far more expensive when its internal sensory component takes more than 10,000 yuan, plus its costs such as appearance design, assembling and maintenance. So 40,000-50,000 yuan shall be spent on such a noise sensor." |
