If your interest lies in CAE, then Code Aster can analyze sound/vibration.

If you are comfortable with MATLAB, you might want to have a look at VIBES Toolbox for MATLAB. Things like TPA, signal processing, octave plots etc are done really easy with it. Most of the code is open so you can see what is going on.

What about hyperworks?
