Ath4 is an acoustic horn shape generator. Constant directivity horns of various shapes and sizes were never so easy to design and test. Create your own model and make a BEM analysis with Joerg Panzer's ABEC to see how it will behave acoustically. Ath4 will prepare all the files necessary with just a few keystrokes. And it's free!
