Robust Fixed-Filter Sound Zone Control with Audio-Based Position Tracking

Sankha Subhra Bhattacharjee, Andreas Jonas Fuglsig, Flemming Christensen, Jesper Rindom Jensen, Mads Græsbøll Christensen
ICASSP 2025accepted

Performance of sound zone control (SZC) systems deployed in practical scenarios are highly sensitive to the location of the listener(s) and can degrade significantly when listener(s) are moving. This paper presents a robust SZC system that adapts to dynamic changes such as moving listeners and varyi…

Sound Zone Control Robust To Sound Speed Change

Sankha Subhra Bhattacharjee, Jesper Rindom Jensen, Mads Græsbøll Christensen
ICASSP 2025accepted

Sound zone control (SZC) implemented using static optimal filters is significantly affected by various perturbations in the acoustic environment, an important one being the fluctuation in the speed of sound, which is in turn influenced by changes in temperature and humidity (TH). This issue arises b…

Broadband Personal Sound Zone Control in the Presence of Nonlinearities

Sankha Subhra Bhattacharjee, Srikanth Burra, Jesper Rindom Jensen, Liming Shi, Guoli Ping, Jingkai Weng +1
ICASSP 2024accepted

Existing literature on sound zone control generally consider the signal model to be linear. However, this is seldom true in practice owing to nonlinear distortions arising from the loudspeakers, especially in consumer applications. In this paper, we propose a new signal model for personal sound zone…

Study And Design Of Robust Personal Sound Zones With Vast Using Low Rank Rirs

Sankha Subhra Bhattacharjee, Liming Shi, Guoli Ping, Xiaoxiang Shen, Mads Græsbøll Christensen
ICASSP 2023accepted

The performance of sound zone control algorithms are known to degrade significantly with changes in acoustic conditions including perturbations of control microphones' positions. In this work, we study the feasibility and effectiveness of using low rank approximations of RIRs to calculate sound zone…

Nearest Kronecker Product Decomposition Based Normalized Least Mean Square Algorithm

Sankha Subhra Bhattacharjee, Nithin V. George
ICASSP 2020accepted

Recently, nearest Kronecker product (NKP) decomposition based Wiener filter and Recursive Least Squares (RLS) have been proposed and was found to be a good candidate for system identification and echo cancellation and was shown to offer better tracking performance along with lower computational comp…
