Electroacoustic Transducer and Array Modeling Tools Ender Kuntsal ITC, a division of Channel Technologies Group (CTG) (Thanks to Matt Staska, ITC) 1 Recent Trends • The availability and the accuracy of transducer and array design software/tools are becoming even more important with the changing economical climate. Fast and affordable computers make this very attractive. • Engineers would like to evaluate their designs more quickly in place of prototyping which requires additional manufacturing and testing time and expense. • The software models must be user-friendly, provide reliable results and also be affordable. • The strength of a transducer and array design engineering team is still extensively based on experience and background, but these design tools make the process more efficient. 2 • ABACUS: Appeared (was chronicled) circa 1200 in China; in Chinese, it is called suan-pan. •SLIDE RULE: GREATEST tool! 3 THEN… Hand crafted 3-D beam patterns from WWII period… 4 NOW… Beam Pattern of a 64 Element Tonpilz Array Calculation Time 2 Minutes 5 General Remarks • There are quite a few transducer and array design software programs used in industry and academia. • Some are based on analytical solutions and some use more complicated numerical meth
