Acoustic Internet of Vehicles: Localization and Sound Synthesis to Increase Traffic Awareness
Wei Zhang, Ling Hua Zhang, Jian‐Jun He · Advanced materials research · 2014
In real life transportation, we sense the environment not only using our eyes, but also using our ears. The acoustic environment contributes a big part of human’s sensing and shall be integrated into the existing internet of vehicles (IOV). The vehicles can communicate with each other via the propagation of the sound they make. The recorded sound signals, with some signal processing applied, can be used to obtain the location of the nearby vehicles and also be sent to the driver to increase his/her awareness of the situation even if the physical sound has been blocked by the door or window of the vehicle. In this paper, we propose such an acoustic IOV using an integrated system of microphone arrays and digital signal processors (DSPs).
