noise reduction [message #19006]

Iï¿½m working as a student for my diploma-thesis on a tool for noise
reduction
with microphones.
Iï¿½ve to examine the noise IN a bottle.
I want to avoid the influence of noise around the bottle.
Therefore Iï¿½ve put two microphones recieving two different signals:
One into the bottle, the other outside.
One microphone recieves the soundl in the bottle and the surrounding
sound,
the other recieves the surrounding sound only.
I want to substract the two signals to reduce the disturbing signal.

Iï¿½ve used my soundcard to record the signal which created a
stereo-wav-file.
This file is to examine by some software.

- Which tool shall I use? IDL or MathLab?
- Is it possible to import the stereo-wav file into IDL / MathLab ?
Or do you have any conversion-tools ?

Do you have any expierence, links, tools, etc. ?

Thanks!
Please answer per mail additionally.
