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 Rangemaster LSK90DFFSS/C Longstock dual fuel cooker 90cm the authors for a single-panel casing in previous publications.However, if even higher noise reduction is required, a dedicated double-panel structure can be employed.In this paper, the sound insulation efficiency of a double-panel Camping Stove 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 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.
