Could cell membranes produce acoustic streaming? Making the case for Synechococcus self-propulsion
Sir James Lighthill proposed in 1992 that acoustic streaming occurs in the inner ear, as part of the cochlear amplifier mechanism. Here we hypothesize that some of the most ancien...

Time delay estimation in the time-frequency domain based on a line detection approach
The estimation of the time delay of arrival (TDOA) or the direction of arrival (DOA) has been an important research topic within the last few decades. In several applications, e.g...

An adaptive microphone array with local acoustic sensitivity
In this paper, a microphone array with 3-D focal zone is proposed. The microphone array consists of one omni-directional and two uni-directional microphones. The microphone array ...

Near-field adaptive beamforming and source localization in the spacetime frequency domain
We revisit the topics of near-field adaptive beamforming and source localization following an alternative approach based on a spatiotemporal spectral representation of the acoust...

Indoor localization without infrastructure using the acoustic background spectrum
We introduce a new technique for determining a mobile phone’s indoor location even when Wi-Fi infrastructure is unavailable or sparse. Our technique is based on a new ambient so...
