While classical Rayleigh streaming, whose circulations are perpendicular to the transducer radiating surfaces, is wellknown, transducer-plane streaming patterns, in which vortices circulate parallel to the surface driving the streaming, have been less widely discussed. Previously, a four-quadrant transducer-plane streaming pattern has been seen experimentally and subsequently investigated throu...

Streaming is a perceptual mechanism by which the brain segregates information from multiple sound sources in our environment and assigns them to distinct auditory streams. Examples for streaming cues are differences in frequency spectrum, pitch, or space, and potential neural correlates for streaming based on spectral and pitch cues have been identified in the auditory cortex. Here, magnetoence...

Auditory streaming refers to the perceptual parsing of acoustic sequences into "streams", which makes it possible for a listener to follow the sounds from a given source amidst other sounds. Streaming is currently regarded as an important function of the auditory system in both humans and animals, crucial for survival in environments that typically contain multiple sound sources. This article r...

This paper presents a hybrid approach for audio segmentation, in which the metric-based segmentation with long sliding windows is applied first to segment an audio stream into shorter sub-segments, and then the divide-and-conquer segmentation is applied to a fixed-length window that slides from the beginning to the end of each sub-segment to sequentially detect the remaining acoustic changes. T...

There is uncertainty concerning the extent to which the auditory streaming effect is a function of attentive or preattentive mechanisms. The mismatch negativity (MMN), which indexes preattentive acoustic processing, was used to probe whether the segregation associated with the streaming effect occurs preattentively. In Experiment 1, alternating high and low those were presented at fast and slow...

Auditory stream segregation involves linking temporally separate acoustic events into one or more coherent sequences. For any non-trivial sequence of sounds, many alternative descriptions can be formed, only one or very few of which emerge in awareness at any time. Evidence from studies showing bi-/multistability in auditory streaming suggest that some, perhaps many of the alternative descripti...

Auditory streaming is a fundamental perceptual component of auditory scene analysis. It manifests itself in the everyday ability of humans and animals to parse complex acoustic information arising from multiple sound sources into meaningful auditory “streams”. While seemingly effortless, the neural mechanisms underlying auditory streaming remain a mystery largely because experiments in non-huma...

Here, a square microchannel acoustophoresis device capable of two-dimensional focusing of sub-micrometer particles is presented. This opens the route to acoustic manipulation of smaller bioparticles such as bacteria. The device performance is compared to a conventional rectangular acoustophoresis channel that focuses particles in one dimension. Utilizing the change in the acoustic streaming vel...

Experiments with an annular thermoacoustic engine employing quasiadiabatic interaction between traveling acoustic waves and an inhomogeneously heated porous material indicate the presence of a closed-loop mass flux. A qualitative modeling of the enthalpy flux in the thermoacoustic core provides an opportunity to estimate the thermal convection associated with this mass flux, by using temperatur...
