Sound field reconstruction using neural processes with dynamic kernels
Zining Liang, Wen Zhang, Thushara D. Abhayapala
Accurately representing the sound field with the high spatial resolution is critical for immersive and interactive sound field reproduction technology. To minimize experimental eff…
A Two-Step Approach for Narrowband Source Localization in Reverberant Rooms
Wei-Ting Lai, Lachlan Birnie, Thushara Abhayapala +3
This paper presents a two-step approach for narrowband source localization within reverberant rooms. The first step involves dereverberation by modeling the homogeneous component o…
An Active Noise Control System Based on Soundfield Interpolation Using a Physics-informed Neural Network
Yile Angela Zhang, Fei Ma, Thushara Abhayapala +2
Conventional multiple-point active noise control (ANC) systems require placing error microphones within the region of interest (ROI), inconveniencing users. This paper designs a fe…
Circumvent spherical Bessel function nulls for open sphere microphone arrays with physics informed neural network
Fei Ma, Thushara D. Abhayapala, Prasanga N. Samarasinghe
Open sphere microphone arrays (OSMAs) are simple to design and do not introduce scattering fields, and thus can be advantageous than other arrays for implementing spatial acoustic…
Spatial Upsampling of Head-Related Transfer Functions Using a Physics-Informed Neural Network
Fei Ma, Thushara D. Abhayapala, Prasanga N. Samarasinghe +1
Head-related transfer function (HRTF) capture the information that a person uses to localize sound sources in space, and thus is crucial for creating personalized virtual acoustic…
Reproducing the Acoustic Velocity Vectors in a Spherical Listening Region
Jiarui Wang, Thushara Abhayapala, Jihui Aimee Zhang +1
Acoustic velocity vectors (AVVs) are related to the human's perception of sound at low frequencies and are widely used in Ambisonics. This paper proposes a spatial sound field repr…
