Feedforward control of double-panel casing for active reduction of device noise

Blog Article

The active casing approach is a technique to reduce noise emission of devices and machinery by controlling vibrations of their casings.This method was successfully validated by the authors for a single-panel casing in previous publications.However, if even higher Diversity Book noise reduction is required, a dedicated double-panel structure can be employed.In this paper, the sound insulation efficiency of a double-panel active casing is evaluated and compared with a single-panel structure by performing a series of laboratory experiments.

The least mean squares algorithm is used to adaptively update control Girls Flats filter parameters.A low-frequency noise in the range up to 500 Hz is considered.Advantages and limits of the proposed approach are pointed out and discussed, and conclusions for future research are given.
