A k-space approach to modeling multi-channel parametric array loudspeaker systems
Tao Zhuang, Longbiao He, Feng Niu +2
Multi-channel parametric array loudspeaker (MCPAL) systems offer enhanced flexibility and promise for generating highly directional audio beams in real-world applications. However,…
Generating Localized Audible Zones Using a Single-Channel Parametric Loudspeaker
Tao Zhuang, Shaozhe Li, Feng Niu +2
Advanced sound zone control (SZC) techniques typically rely on massive multi-channel loudspeaker arrays to create high-contrast personal sound zones, making single-loudspeaker SZC…
Experimentally Probing Non-Hermitian Spectral Transition and Eigenstate Skewness
Jia-Xin Zhong, Jeewoo Kim, Kai Chen +3
Non-Hermitian (NH) systems exhibit intricate spectral topology arising from complex-valued eigenenergies, with positive/negative imaginary parts representing gain/loss. Unlike the…
Deep Learning-Based Approach for Identification and Compensation of Nonlinear Distortions in Parametric Array Loudspeakers
Mengtong Li, Tao Zhuang, Kai Chen +2
Compared to traditional electrodynamic loudspeakers, the parametric array loudspeaker (PAL) offers exceptional directivity for audio applications but suffers from significant nonli…
The feasibility of sound zone control using an array of parametric array loudspeakers
Tao Zhuang, Jia-Xin Zhong, Jing Lu
Parametric array loudspeakers (PALs) are known for producing highly directional audio beams, a feat more challenging to achieve with conventional electro-dynamic loudspeakers (EDLs…
