(...) I would be interested, but I have no audio equipment (apart from a function generator) Very interesting data BTW! Philo (16 years ago, 28-Feb-09, to lugnet.robotics, lugnet.boats)

(...) Excellent suggestion!!! We'll open one sensor and try once again. (...) (URL) else interested in repeating the experiment? Philo? Claude P.S. I added a graph to the page, where the sound pressure is maintained constant. (16 years ago, 28-Feb-09, to lugnet.robotics, lugnet.boats)

(...) Since I was doing this all manually, it was by far the easiest. I realized that a better way would be to vary the signal generator level at each frequency, but often when trying that I simple "maxed out" the reported level from the sound (...)

Thanks Brian (...) Your excellent graph shows that you tried to maintain the sound pressure constant. We did the inverse in the last graphs, where we tried to draw the curve for a constant NXT sensor value. We also repeated the experiment, and this (...)

(...) anything interesting at 3 kHz... perhaps because I didn't go that high (oops). To figure out the frequency response I did it manually: I borrowed a signal generator and speaker from the university, as well as a sound meter, and then simple (...) (16 years ago, 28-Feb-09, to lugnet.robotics)

(...) That is great news. It means it should be relatively easy to add any new parts LEGO introduces (like the treads, or the NXT cables) without having to change the actual program. I'm looking forward to the release. Jetro (16 years ago, 27-Feb-09, to lugnet.cad, FTX)

We've worked some hours to do some interesting experiments with the NXT sound sensor in order to learn more about the sensor characteristics: Please consult: (URL) and help discussing. Claude Baumann (16 years ago, 27-Feb-09, to lugnet.robotics)
