Hi Jean-Michel,

Thanks for the thanks :-).

< I don't know why I obtain an error message when simulating the directivity of a horn calculated by my method. I probably do something wrong... >

I doubt that you are doing anything wrong. Does your computer have an AMD Athlon processor, by any chance? Several people have reported directivity calculation problems when using an Athlon processor. I have not been able to generate the error myself - I have an Intel Pentium 4 machine running Windows XP.

< I would suggest for a further version to allow T value larger than 1 >

T has been limited to a maximum value of 1 (exponential wavefront area expansion) because of concerns I have regarding the accuracy of the throat acoustical impedance predictions when larger values of T are used. I had also assumed (perhaps incorrectly) that there would be little requirement for a practical Le Cléac'h horn with T > 1.

Kind regards,

David
