RISThe Analysis of Structural–Acoustic Coupling of an Irregular Enclosure Under the Excitation of Point Force and PVDF
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The physical model of this paper is an irregular enclosure with double flexible plates. The primary source is the vibration of Plate A excited by a point force. The secondary source is the ...
A Biologically Inspired Coupled Microphone Array for Sound Source Bearing Estimation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Ormia ochracea, a species of parasitic fly, has a remarkable localization ability despite the tiny interaural distance compared with the incoming wavelength. The mechanical coupling between its ears enhances the ...
Study of Response Difference Amplification and Bionic Coupled Circuit in Small Acoustic Array for Spatial Localization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Precisions of localization are a function of the size of an array. A kind of parasitoid fly, Ormia ochracea, performs an extraordinary directional hearing ability despite its tiny-scaled auditory organ. In this paper, ...
A Miniature Four-Microphone Array for Two-Dimensional Direction-of-Arrival Estimation Based on Biomimetic Time-Delay Magnification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A miniature microphone array based on interaural time difference (ITD) is designed. This array contains four microphones with certain arrangement and aims for two-dimensional (azimuth and elevation) direction-of-arrival ...
