Thank you! I'm not sure these are Mac compatable, though. I know the second one isn't. Have you ever tried Raven? http://www.birds.cornell.edu/brp/raven/Raven.html

Hmm. Very interesting. So you mean that there are some sounds (like turbulence) that have no dominant (outstanding) pitches? But if the signals of the noise are "random", doesn't that still imply that they exist? And if so, isn't there some kind of analysis software that could capture the sound...

Thanks once again. By "analyze", I mean somehow capturing the unique characteristics of a given sound (jet engine, motorcylce, etc) in time in some kind of notation (like a graph). It is easy to notate music, because the pitches are very easy to distinguish. But in the case of an engine, it is...

That's excellent, rbj. Thank you so much for taking the time to explain clarify these matters (and thank you again billiards for your reply!) If you are indeed the guru on this matter (I do not doubt it!), then I would very much appreciate it if you would answer my main question: how can we...

Thank you! Your description of pitch/frequency was quite clear. As for your definition of "noise", I am familiar with that textbook definition of noise as "unwanted sound" and that is not at all what I'm referring to. I used the term "noise" because I can't think of a better term for it, but...

Thank you. I had actually read those articles before, and found the 2nd one especially helpful. The Wikipedia article about white, red, and pink noise makes no sense to me, because it never really puts it into layman's terms by providing an example. In the case of the jet engine, does...

Great! Thanks for the reply! 1)So is there a technical term for this spread of pitches? 2)How can we determine what pitches are in the spread? Would a spectrogram analyze it?

Hello everyone. I'm not a Physics major: I'm a Music major. And I have a question. I've read various books on acoustics, but I still haven't found the answer. Ok. The way I see it, there are 2 basic types of sounds (I didn't get this out of a book, it's my own conclusion from everyday...
