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…

Generation of Personal Sound Fields in Reverberant Environments Using Interframe Correlation

Liming Shi, Guoli Ping, Xiaoxiang Shen, Mads Græsbøll Christensen

ICASSP 2022accepted

Personal sound field control techniques aim to produce sound fields for different sound contents in different places of an acoustic space without interference. The limitations of the state-of-the-art methods for sound field control include high latency and computational complexity, especially in the…
