The acoustical behaV:iour of simple horns of parabolic, conical and exponential profile is analyzed
and explicit expressions are given for the impedance coefficients Zii. Wavefront curvature effects are
included and the discussion is extended to investigate the effect of oblique truncation, which gives
the horn a shape closely similar to that of a typical vertebrate pinna. The effects of higher modes.are
discussed qualitatively and the conditions under which these can be neglected are...[Show more]
