Computer aided auto-construction of various types of folded horns and acoustic analysis of coupled horn and driver systems are presented in this thesis. A new
procedure is developed for auto construction of folded horn shapes. Linear graph modeling technique is employed for specification of horn driver output in terms of
diaphragm velocity or throat pressure. In the final phase of the design procedure, acoustic analysis of folded horns is carried by means of finite element analysis. A
commercial software package MSC.ACTRAN is used to calculate directivity patterns and resulting acoustic pressure in the free field. Horn geometry consisting of linear, exponential, hyperbolic and tractrix shapes is
automatically constructed by parallel working of Delphi and finite element analysis program. The enclosure bordering the horn contours are considered rigid in the analyses. Maximum number of folding is limited to two. This study is made possible
to evaluate the performance of these four types of horn contours for a specified range of frequencies.
