Sound-Level-Measurement with Matlab?

    I am a very beginner with MATLAB and I want to ask whether it is
    possible to use MATLAB as a "sound level meter". A collegue suggested
    it to me, and if somebody could help me, I would be very

    I´m using 3 ICP-microphones and -signal-conditioning-modules and a
    8-channel RME Hammerfall DSP multiface as an A/D-converter.

    Is there any - perhaps very easy - possibility of using MATLAB for
    displaying A-weighted or non-weighted dBSPL-levels?

    The levels I´m going to measure will be between approximately 60dB(A)
    and 110dB(A).

    Thanks a lot!

    Best regards,

    I nearly forgot: It would also be neccesary to do a spectral
    analysis. Thanks a lot!

    Dear Jan,

    we do have such a program which runs on top of our SINUS Measurement
    Toolbox (SMT) for MATLAB - however, this is only available on our
    hardware. Please take a look at our website and contact me via
    "[email protected]" if you're interested.

  4. Hi Jan,

    I think Matlab is an excellent choice for such a task, but you'll need
    the Data Acquisition toolbox and you'll need to make sure your hardware
    is supported.

    I would also recommend equipment from a company called
    Tucker-Davis-Technologies, which I used a few years ago. I assume they
    are still around, but $$$.
