Wireless Acoustic Sensor Networks

Comments Off on Wireless Acoustic Sensor Networks


A wireless sensor network (WSN) is a network of spatially distributed sensors aimed at monitoring different physical or environmental parameters. In the context of acoustic signal processing, the use of low-power, low-cost acoustic sensors with computing capabilities offers new opportunities for the development of new applications and processing strategies, different from the ones established by usual microphone array arrangements. The most significant advantage of a WSN over a traditional (wired) array is that it enables an increased spatial coverage by distributing sensors over a larger volume, providing a scalable and easy to deploy structure with better signal to noise ratio properties.
