   Hi all,

   I am trying to write a code where I simulate playing a pulsed 1kHz tone from 1 or more speakers out of an entire array (3x3) at 5 different distances. I then have a code where I can input the "actual speaker" that is making the noise and I can see the error between what speaker(s) was calculated and what speaker(s) was actually being used. Ultimately I want to show that error increases as distance from the sound source increases. Does anyone have any general advice on this? I have some code written, and it seems to be running well, but my sensor_data is not of the form that I would like, and I'm not sure why..

   I am new to here so I am not sure how to post my code appropriately, but I would be glad to do so with some instruction.

   Best

   Hi nickbruno,

   If it's a single file, you can just copy and paste your code to the forum (it's not possible to upload files).

   Regarding the format of sensor_data, the best place to start is the examples (these are accessible under the k-Wave heading in the MATLAB help browser), and the k-Wave manual.

   One thing to check is that your source only contains frequencies supported by the computational grid. This can be enforced using the filterTimeSeries function.

   Brad.
