RISFunctional Generalized Inverse Beamforming Based on the Double Layer Microphone Array Applied to Separate the Sound Sources
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Beamforming based on microphone array measurements is a popular method for identifying sound sources. However, beamforming has many limitations that limit their precision. These limitations are addressed in research. To ...
Application of Inverse Patch Transfer Functions Method With Wideband Holography Algorithm to Sparsely Distributed Sources Identification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Inverse patch transfer functions (iPTF) method has been developed to reconstruct the sound field of irregularly shaped sources in a noisy environment. The iPTF method, which uses classic regularization methods to solve the ...
Denoising Weighting Beamforming Method Applied to Sound Source Localization With Airflow Using Microphone Array
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Conventional frequency domain beamforming (FDBF) relies on the measured cross-spectral matrix (CSM). However, in wind tunnel tests, the CSM diagonal is contaminated by the interference of incoherent noise after long-time ...
