Doppler effect in the time-domain beamforming for rotating sound source identification.
Journal of the Acoustical Society of America, 2020Identifications of rotating sound sources are of interest in many industrial applications. The most famous beamforming to identify rotating sound source is the time-domain ROSI beamforming proposed by Sijtsma et al. (AIAA 2001-2167, 2001).

SPRSound: Open-Source SJTU Paediatric Respiratory Sound Database
IEEE Transactions on Biomedical Circuits and Systems, 2022It has proved that the auscultation of respiratory sound has advantage in early respiratory diagnosis. Various methods have been raised to perform automatic respiratory sound analysis to reduce subjective diagnosis and physicians' workload.

An asymptotic expansion has been derived from a formula given by W. N. Brown, which allows the plotting of directional and response curves for a vibrating cone in an infinite baffle. The results are compared with those pertaining to a flat disk of same radius.

Sources of Underwater Sound and Their Characterization
2016Because of the history of sonar and sonar engineering, the concept of "source level" is widely used to characterize anthropogenic sound sources, but is it useful for sources other than sonar transmitters? The concept and applicability of source level are reviewed for sonar, air guns, explosions, ships, and pile drivers. International efforts toward the

Sound-source localization when listeners and/or sound sources move
The Journal of the Acoustical Society of America, 2021In the dynamic everyday world, sound sources and/or listeners move when animals attempt to localize sound sources. Determining sound-source locations in these dynamic scenarios requires several computations by the brain. The auditory-spatial cues (Interaural Time Differences, ITDs; Interaural Level Differences, ITDS; and spectral cues associated with ...

Sound Source Separation Apparatus And Sound Source Separation Method
The Journal of the Acoustical Society of America, 2011To shorten an output delay while a high sound source separation performance is ensured when a sound separation process based on an ICA method is performed. A second Fourier transform process execution cycle t2 for obtaining a second frequency-domain signal S1 used as an input signal of a filter process is set shorter than a first Fourier transform ...

According to Lighthill’s theory, one may distinguish sound sources in a free flow in terms of monopoles, dipoles, and quadrupoles [1]. The volume flow itself is irrelevant for monopole sound generation. It is the variation in time of the volume determined by the fluctuating mass flow, which generates sound.
