Title: Active sound eliminating device
Inventor: IWASE KOJI
IPC: G10K11/178
Filed: 1992-06-01
Abstract: PURPOSE:To provide the sound eliminating device for a multi-input/multi-output system for up to high frequencies by dividing coefficients of an adaptive filter into plural blocks and updating the coefficients of the adaptive filter alternately each time data are sampled, and then reducing an arithmetic quantity required to update adaptive filter required for active sound elimination. CONSTITUTION:The adaptive filter coefficients are divided into four areas, which are switched each time data of A/D converters 3 and 6 are sampled to update the adaptive filter 10. For the update, specific LMS (method of least squares means) algorithm is employed. Arithmetic required for each sampling process of a microcomputer 15 consists principally of the convolution integration of an adaptive filter weight function and a reference signal (x), the convolution integration of a spatial filter transfer function and the reference signal, the execution of the LMS algorithm, the movement of data of the reference signal (x) and a virtual reference signal, etc. Assuming that the adaptive filter weight function and spatial filter transfer function are equal in the number of taps, the arithmetic quantity of the update part of the adaptive filter 10 becomes about 1/3 and the coefficients are divided into four to reduce the total arithmetic quantity by 20%.
