help me to design a noise measuring device

[/b]hi friend ,can you help me to design a circiut for measuring electronic and electrical noise in a industry .
i am a final year student of electronics . can you help me to find out sites on noise measuring circuits .i am in doubt how to copact a pre charge amplifier to a chopper stablizes amplifier .which transducer to use to measure the tribeoelectric effect .
can you tell me where shall i get the info about this .

Do you mean electromagnetic radiation? What frequency range, what intensity (microvolts/meter)?

yes i am talking about the noise in the cables carrying signal.they are affected due to trieboelectric effect ie is noise generated due to vibrations ,due to stray capacitance and yes in microvolts/meter.if you want to known more of this i can mail you my synopisis.tell me your email id i will do it .my mail id is anand_andyboy@indiatimes.com.
