Analytic Methods of Sound Field Synthesis by Jens Ahrens

By Jens Ahrens

This booklet places the focal point on serving human listeners within the sound box synthesis even though the procedure may be additionally exploited in different functions reminiscent of underwater acoustics or ultrasonics. the writer derives a primary formula in line with common fundamental equations and the single-layer power strategy is pointed out as a useful gizmo on the way to derive a basic answer. He additionally proposes extensions to the single-layer strength procedure which permit for a derivation of particular recommendations for round, planar, and linear distributions of secondary resources. in line with above defined formula it truly is proven that the 2 confirmed analytical ways of Wave box Synthesis and Near-field Compensated greater Order Ambisonics represent particular recommendations to the final challenge that are coated by means of the single-layer power resolution and its extensions.
