Circular microphone array with tangential pressure gradient sensors
Circular microphone array with tangential pressure gradient sensors
Microphone arrays have already been successfully applied to record sound fields. They are typically composed of pressure sensors and different designs have been suggested, each trying to overcome practical difficulties, such as transducer noise, spatial aliasing and non-uniqueness of the inverse solution. Typical designs are of spherical (3D) or circular form (2D) and use pressure sensors. The array corpus is usually either solid or as acoustically transparent as possible.
In this paper, the theoretical model of a circular microphone array, observing the tangential component of the pressure gradient on its boundary is presented.

Abstract
Microphone arrays have already been successfully applied to record sound fields. They are typically composed of pressure sensors and different designs have been suggested, each trying to overcome practical difficulties, such as transducer noise, spatial aliasing and non-uniqueness of the inverse solution. Typical designs are of spherical (3D) or circular form (2D) and use pressure sensors. The array corpus is usually either solid or as acoustically transparent as possible.
In this paper, the theoretical model of a circular microphone array, observing the tangential component of the pressure gradient on its boundary is presented.
