Sons al balcó: Soundscape Map of the Confinement in Catalonia

Abstract

In this project, we aim to study the effect that the lockdown due to the COVID-19 pandemic has caused on the perception of noise in Catalonia. In Sons al Balcó, the research activities cohabit with the dynamic collaboration with citizens and other stakeholders to create social and environmental impact, to widen awareness and design tools to improve citizenship development and empowerment. The initial scientific hypothesis is that the annoyance coming from outdoor noise, minimized by the lockdown effect, could be associated with better perception of the soundscape by people. Sons al Balcó allows validating this hypothesis in two different ways. On the one hand, by means of subjective questionnaires conducted to people living in pre-defined diverse acoustic areas (urban, suburban and rural environments), and on the other hand, by the use of objective measurements of the noise levels, and the study of the soundscape in these areas, using short pieces of video collected by citizens. For this purpose, we designed an on line test to be conducted by any citizen aiming to contribute to this wide study for all the territory of Catalonia, both from rural areas and from cities. A communication campaign was conducted to reach a significant participation. During the lockdown, more than 350 questionnaires and videos were collected, and a first map of the soundscape of the confinement in Catalonia was depicted.
