The Time-Reversal Acoustics in Ergodic Cavity - Some Simulation and Experiment Results

摘要

In this paper, we address the possibility of time-reversal acoustics (TRA) in a simulated space, which is constructed by a stacked-neuron array (SNA). In the simulated space, although it is highly discrete, the temporal focusing and the spatial focusing can still occur as that in a realistic space. We numerically evaluated the performances of these focusing effects. By this research, we aim to modeling of the space in artificial devices in the sense of acoustics and to providing clues for how the space is managed, or modeled in the human auditory or in the brain.
