• Abstract: We describe a new method for estimating the direction of sound in a reverberant environment from basic principles of sound propagation. The method utilizes SNR-adaptive features from time-delay and energy of the directional components after acoustic wave decomposition of the observed sound field to estimate the line-of-sight direction under noisy and reverberant conditions. The effectiveness of the approach is established with measured data of different microphone array configurations under various usage scenarios.

  An environment acoustic model represents how sound is transformed by the physical characteristics of an indoor environment. We propose active acoustic sampling, a new task for efficiently building an environment acoustic model of an unmapped environment. We introduce ActiveRIR, a reinforcement learning policy that leverages information from audio-visual sensor streams to guide agent navigation and determine optimal acoustic data sampling positions.

  We study the effect of local unitary noise on the entanglement evolution of a two-qubit system subject to local monitoring and inter-qubit coupling. We construct a Hamiltonian by incorporating the noise into the Chantasri-Dressel-Jordan path integral and use it to identify the optimal entanglement dynamics. Numerical investigation of long-time steady-state entanglement reveals a non-monotonic relationship between concurrence and noise strength.
