Seminars Audio Signal Processing for Noise Mapping in Smart Cities Seminar (Vídeo YouTube) about noise monitoring in smart cities, using Wireless Acoustic Sensor Networks and their application to the monitoring of enviornmental acoustics during the lockdown derived from the COVID-19 pandemic, presented within La Salle Sustainability Lectures, organized by De La Salle University, Manila (Phillipines).Summary: Environmental noise can be defined as the accumulation of noise pollution caused by sounds generated by outdoor human activities, being traffic noise the main source in urban areas. To address the negative effects of environmental noise on public health, the European Environmental Noise Directive requires EU member states to tailor noise maps and define the corresponding action plans every five years for major agglomerations and key infrastructures. Noise maps have been hitherto created from expert-based data collected using certified devices through static and costly measurements. However, this classic approach has recently undergone a change of paradigm thanks to the emergence of the so-called Wireless Acoustic Sensor Networks under the Internet of Things and Edge Computing paradigms, which can be used to measure and manage the noise pollution in Smart Cities in a more dynamic manner. One of the projects that has been developed following this new approach is the LIFE+ DYNAMAP projects, aimed at developing a dynamic noise mapping system able to detect and represent in real time the acoustic impact of road infrastructures, thus, being focused on road traffic noise levels computation and mapping in real-time. This talk will describe the key steps of the audio signal processing algorithm developed to avoid biasing the noise levels computation due to the presence of non-traffic acoustic events, together with the main challenges of their application for computing dynamic traffic noise maps in real-life environments, and the consequences of the COVID-19 pandemic on the monitored pilot areas. Fecha: September, 29, 2021 Horario: from 13:00 to 14:00 h (CET) Audio Signal Processing for Dynamic Noise Mapping in Smart Cities Seminar about noise mapping, paying special attention to Wireless Acoustic Sensor Networks and the challenges posed by this change of paradigm within the Smart Cities at CIMNE-UPC, invited by Dr. Joan Baiges.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.
