# Sound-Level-Measurement with Matlab?

Hi,

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,

Jan

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.

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 \$.
