Mechanical Acoustics/Vibration engineering FAQ

Introduction to Signal Analysis for Acoustics
Posted: 24 May 03 (Edited 22 Sep 03)

Here is an excellent, reasonably practical introduction to using and understanding a spectrum analyser. If you don't know much about Fourier, FFTs, windows, and calibrating then this is a good start.

If that is a bit too dry then ElectricPete recommends www.dspguide.com
This looks to me like signal processing with attitude, entertaining and a good intro. It might well tell you everything you need to know, and the approach is about as non-mathematical as is practical.

This has more details about FFTs

Here is an excellent discussion of the philosophical details of FFTs and wavelets.

This is Tom Irvine's website. He has written many useful papers on real signal analysis problems. There are also a large number of tutorials and examples there. http://www.vibrationdata.com/

Art Ludwig is a physicist (I think) and contributes to the alt.sci.physics.acoustics newsgroup, and is very interested in setting his stereo up. His website includes a lot of room acoustics theory, and psycho-acoustics.

Lecture notes on a course in hearing. Seems to be biased towards music and psycho-acoustics
