Abstract

A process is disclosed for producing polarized acoustic fields. The directionality thereby obtained in a very wide auditory range, even with a very small monolithic, purely passive system, results in a subjectively unusually broad spatial stereo effect. The ability of bodies (acoustic "conductors", including "insulators" or action reflectors for mirror sources) to create at least one spatial preferred direction for the wave progression by means of internal structuring, special geometries and surfaces is exploited to this end (polarization). Longitudinally structured bodies, especially clusters of capillary tubes, have this ability and favour one longitudinal component of the acoustic progression. The record-side acoustic 3-D space appears to be reproducible in phase using acoustic transducers according to the process to a large extent without electronic aids. However, active smoothing of frequency-response and phase-response advantageously compensate for certain system-related features. Electronic delay units simulate the behaviour of the enclosure of a system according to the invention and improve its characteristics.
