To answer European Union instruction, solve Europe much noise question passes among town, european researcher developed map of sound wave of model of a kind of three-dimensional computer a few days ago, the color that passes commutation indicates the noise origin of different grade. Map of this kind of sound wave can decide the urban noise grade of what place exceeded the range that people can accept, adopt measure to reduce the harm that these noise bring to the mankind thereby. Current, the case Dan Sike that has led preexistence Poland by an international group that England heads begins to undertake project of first sound wave map experiments.
According to British media coverage, according to “2002 year ” of instruction of noise of European Union environment, enclothe all Europe main city, sound wave map that covers population amount to exceed 250 thousand to plan to will be started in September 2006. Because this is in a year of future, join the procession that asks to the instruction as more town, technology of sound wave scale will be able to travel quickly. It is reported, “2002 year of ” of instruction of noise of European Union environment putting forward was 1966 the immediate result that the European Union discusses a report about noise policy, its purpose is to be the noise problem that solves European Union area to reach consensus. The basis unites country of member of instruction requirement European Union noise index, draft for highway artery, railroad, airport and ground of population inhabit a region graph of noise sound wave.
Noise supervises the explanation of a spokesman of the project to say: The purpose of map of “ scale noise is to understood the town noise of what grade to exceed the level that can accept, thereby final can the global map that scale gives to get noise menace area. These maps will be used noise suffers to affect inside assess Europe limits respectively and feel rusty with the number that cannot fall asleep. ”
Such sound wave map is hopeful the European environment office that is set in Copenhagen to provide a data, in order to build database of an Europe center. Press a plan, the first batch of maps in scale of ground of main population inhabit a region will at a year later, namely metaphase was started 2007. Subsequently, take the effect that come to ground of onefold population inhabit a region to evaluate noise, the sound wave map of case Dan Sike and other town updates every 5 years. This spokesman complement says: This one project still will be “ alleviate noise offers a means of settlement, build potential protection system. The researcher of maritime technology company expresses the England that ” is engaged in sound wave map developing the work: “ for scale this one map, the system of this one IT that we invent will allow according to industry mark, all these information store centrally database, go to the lavatory thereby people is in small towns hall or it is through Internet such communal channel gets these information. In the meantime, it still facilitates automatic or it is semi-automatic data-in, can upgrade and open to the outside world. In the future, this one system will perfect the environmental database that is a conformity stage by stage, so that be on imitate or the data base that are a standard, undertake integration analysis to town environment. ” participates in the Owen Harrop of this job to say: “ noise is evaluated and management has become an increasingly serious topic for discussion of European. As Europe each are big ceaseless actively answers the city European Union instruction, this one market is destined to want to develop flourishingly in the future. ”
