Dear Shen I think you are looking for the function Pascalize http://www.acoustics.hut.fi/software/HUTear/HUTear2/HUTear/Pascalize.m from the HUTear Matlab Toolbox http://www.acoustics.hut.fi/software/HUTear/ You just need to edit it so that it uses the line b=10^(-1.5); 30 dB rule and the you should be fine. :) stefan -- Dipl.-Math./Inf.
