How to obtain the channel impulse response through sound pressure levels

Dear all,

I would like to obtain the channel impulse response through the sound pressure level.

How can I do that? Is there any routine in matlab that do that automatically?

Thank you in advance.

hello

what data do you have ? a transfer function or a direct measurement of the impulse ?

you can compute the IR from a FRF using ifft

Hello Mathieu,

The only thing I have is a matrix that corresponds to the sound pressure levels (see the attached file).

Thank you!

huh ?

what's that ? SPL above 200 dB ?? that'smore then SaturnV noise levels on the launch pad

joke aside I don't see how a noise vs range vs depth map can be translated into frequency response or impulse response...

I assume your map is valid for a broadband "generic" signal but that is not something that can be used for FRF / IR computation

may I ask what this map is related to ?
