Abstract

Noise maps have been historically collected and generated by means of costly expert measurements using certified devices. However, this classic approach has recently undergone a change of paradigm thanks to the emergence of the so-called Wireless Acoustic Sensor Networks, which can be used to measure and manage the noise pollution in Smart Cities dynamically. This change of paradigm poses some specific challenges, being some of them derived from the automation of data collection and their subsequent signal processing. This seminar will describe the key steps of the audio signal processing together with the main challenges of their application for computing dynamic traffic noise maps in real-life environments.
