In the conventional hybrid active noise control (CHANC) algorithm, the filtered-x least mean square (FXLMS) algorithm is used in both feedforward and feedback structures. However, the FXLMS algorithm does not process the reference signal and the error signal before updating the weight vector, which leads to the inadequate robustness of the CHANC algorithm in the impulsive noise environment. To solve this problem, the maximum versoria criterion is incorporated into the HANC (MVC-HANC) algorithm in this paper. Firstly, the MVC-HANC algorithm employs a novel nonlinear function to compress the error signal. Secondly, the proposed algorithm uses the modified sigmoid function to constrain the reference signal. To further improve the noise attenuation performance, the MVC-HANC algorithm uses a novel exponential function to adjust the step-size adaptively. Simulation and experiment results demonstrate that the proposed algorithm has the better attenuation performance than the conventional HANC algorithm.

“…On open windows, this section has shown that passive and active concepts are potentially suitable for aircraft noise reduction albeit further work is required for performance optimization. Even though promising outcome has been demonstrated in open windows incorporated with ANC system, some researchers [164] , [184] remain skeptical about the concept, arguing that it may be impractical for application in housing estates especially over a prolong period of time under different weather conditions. Considering the interior design of modern apartments, residents may not be attracted to the concept due to poor aesthetics, not to mention the need for additional circuitry and maintenance.…”

“…Furthermore, recent studies have shown that the improved algorithms have increased the processing speed, enabling their applications to the higher frequencies and the larger spaces [1]- [5]. In addition to this, ANC has been employed for open windows, allowing air flows with an array of speakers and microphones [6]- [8]. However, in principle, ANC's performance is poor for high-frequency noise owing to the limitations in processing speed.…”

Acoustic filters provide sound insulation unpleasant noises at a specific frequency only. Ordinary passive acoustic filters made up of acoustic metamaterial structures can work without a power supply. However, their working frequency is not adjustable. This study reports a tunable open planar acoustic notch filter that incorporates a pneumatically controlled Helmholtz resonator (HR) array. The HR array consisted of three layers: cavities, a membrane, and microchannels. The cavities function as the HR chambers, whose volume determines the resonant frequency. The acoustic wave is effectively attenuated at this frequency owing to the HR effect. The HR chamber volume can be varied by displacing the stretchable membrane with air pressure through the microchannels. This helps in adjusting the resonant frequency, thereby realizing a tunable acoustic notch filter. We conducted theoretical, and experimental examinations along with simulations of the frequency response for an HR array with three different cavity thicknesses. The prototype device realized a frequency tuning of approximately 4.1-4.9 kHz with 10 dB filtering. Furthermore, an improved notch frequency tunability was observed for the thinner cavities, along with a decrease in the notch performance. Thus, the proposed HR array filter can be useful for high-frequency noise that is generally uncomfortable for humans.
