Abstract Brain Source Localization (BSL) using Electroencephalogram (EEG) has been a
useful noninvasive modality for the diagnosis of epileptogenic zones, study of evoked …

Beamforming using spherical microphone arrays (SMAs) with processing in spherical
harmonics (SH) domain is widely being studied. This is due to the ease of array processing …

Traditional spherical sector microphone arrays using omnidirectional microphones face
limitations in modal strength and spatial resolution, especially within spherical sector …

Spherical microphone arrays (SMAs) are widely being used for source localization and
separation. However, it is uneconomical to build a full SMA when sources are present in …

Developing spherical sector harmonics (SSHs) benefits sound field decomposition and
analysis over spherical sector regions. Although SSHs demonstrate potential in the field of …

Acoustic imaging technology has the advantages of non-contact and intuitive positioning. It
is suitable for the rapid positioning of defects such as the mechanical loosening, discharge …

Sound field recording aims to capture and preserve the information of the sound field in a
specific area. Typically, the recorded sound field is decomposed as a superposition of a set …

Drones are becoming a part of our lives, but its noise pollution is an annoying problem. In
this paper, we propose a spherical sector harmonics based noise reduction method that can …

The detection equipment based on a microphone array is widely used. At present, there are
many redundant array elements in the microphone array, which significantly affects the main …

The development of spherical sector harmonics benefits the sound-field decomposition and
analysis over a spherical sector region. However, research on the soundfield radial …
