Active Noise Control

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.

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.
This paper:
1. Proves the frequency-band-match method.
2. Propose a SANC based on a partitioned frequency
domain filter.
3. Both simulation and real-time experiment is
carried out to validate the algorithm.

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

Study on the use of error term in parallel-form narrowband feedback active noise control systems (slides)


Parallel-form narrowband feedback active noise control (FBANC) system has been shown to perform better than conventional internal model control (IMC) based FBANC system in cancelling multi-tonal noise. A previous paper illustrated a novel approach in estimating the frequencies of the multi-tone noise, and using an internal tonal generator cum frequency grouping unit to increase its frequency separation in each channel of the parallel-form FBANC system based on a full-band error.
