Feedforward Spatial Active Noise Control Based on Kernel Interpolation of Sound Field


A method for feedforward active noise control (ANC) over a spatial region is proposed. Conventional multipoint ANC aims to reduce the noise at multiple discrete positions; therefore, the noise reduction in the region between these points cannot be guaranteed. Recent studies revealed the possibility of spatial ANC, i.e., noise control in a continuous target region.

Global and Local Mode-domain Adaptive Algorithms for Spatial Active Noise Control Using Higher-order Sources


The aim of spatial active noise control (ANC) is to attenuate noise over a certain space. Although a large-scale system is required to
achieve spatial ANC, mode-domain signal processing makes it possible to reduce the computational cost and improve the performance.
A higher-order source (HOS) has an advantage in sound field control due to its controllable directivity patterns. An array of HOS
can suppress an undesired exterior sound propagation while occupying a smaller physical space than a conventional omnidirectional

Time domain Spherical harmonic analysis for adaptive noise cancellation over a spatial region


Active Noise Cancellation (ANC) is a well researched topic for minimizing unwanted acoustic noise, and spatial ANC is a recently introduced concept that focuses on continuous spatial regions. Adaptive filter designing for spatial ANC is often based on frequency-domain spherical harmonic decomposition method, which has a major limitation due to the increased system latency. In this paper, we develop a time-domain spherical harmonic based signal decomposition method and use it to develop two time-space domain feed-forward adaptive filters for spatial ANC.

On the Comparison of Two Room Compensation / Dereverberation Methods Employing Active Acoustic Boundary Absorption


In this paper, we compare the performance of two active dereverberation techniques using a planar array of microphones and loudspeakers. The two techniques are based on a solution to the Kirchhoff-Helmholtz Integral Equation (KHIE). We adapt a Wave Field Synthesis (WFS) based method to the application of real-time 3D dereverberation by using a low-latency pre-filter design. The use of First-Order Differential (FOD) models is also proposed as an alternative method to the use of monopoles with WFS and which does not assume knowledge of the room geometry or primary sources.

MODE DOMAIN SPATIAL ACTIVE NOISE CONTROL USING SPARSE SIGNAL REPRESENTATION


Active noise control (ANC) over a sizeable space requires a large number of reference and error microphones to satisfy the spatial Nyquist sampling criterion, which limits the feasibility of practical realization of such systems. This paper proposes a mode-domain feedforward ANC method to attenuate the noise field over a large space while reducing the number of microphones required.

Selective active noise control (SANC) is a method
to select a pre-trained control filter for different

A Novel Selective Active Noise Control Algorithm to Overcome Practical Implementation Issue


Selective active noise control (SANC) is a method to select a pre-trained control filter for different primary noises, instead of using conventional real-time computation of the
control filter coefficients. SANC has the advantage of improving the robustness of control filter while reducing the
computational complexity. This paper presents a practical

Reference Signal Generation for Broadband ANC Systems in Reverberant Rooms


One major issue of implementing broadband active noise control systems in reverberant
rooms is the lack of reference signals. In this work, by exploiting the spatial sound
field characteristics, a time-domain sound field separation method is developed to
generate the reference signal for broadband active noise control systems in reverberant
rooms. The time-domain sound field separation method separates the outgoing field produced
by the primary source from the secondary source feedback and room reverberation on a
