Method for implementing internet based noise measurement and noise environment database system

摘要

PURPOSE: A method for implementing Internet based noise measurement and constructing a noise environment database system are provided to supply a technique for measuring a noise rate by a micro phone and a PC by supplying a technique for measuring a noise of an external environment of user using the PC, a general mike, and a program on the Internet. CONSTITUTION: User information as geographic information and an external environment by connecting a user to the corresponding web site is inputted, and user system environment information of hardware information as a kind of a sound card and a microphone is inputted. A noise rate measuring program based on the Internet is downloaded through the Internet in a server computer and a noise measured using a micro phone being connected to a user computer is received as an analogue voltage signal, and a digital signal of a measured noise being transmitted from the sound card is read(3). A measured noise value is corrected for correcting a distortion of a noise by the micro phone and the sound card being connected to the user computer(4). A necessary noise rate is calculated using the digital value received from the sound card(5). The user computer displays a noise rate of an external environment of the user(6) and transmits the noise rate to a noise measuring and a noise environment database of the server computer through an Internet line(7). The noise rate is classified in accordance with information inputted by the user(8) and the classified noise rate is stored in the database(9).
