Immersive 3D Soundscape: Analysis of Environmental Acoustic Parameters of Historical Squares in Parma (Italy)

Sound source localization represents one of the major challenges for soundscapes due to the dynamicity of a large variety of signals. Many applications are found related to ecosystems to study migration process of birds and animals other than other terrestrial environments to survey wildlife. Other applications on sound recording are supported by sensors to detect animal movement. This paper deals with the immersive 3D soundscape by using a multi-channel spherical microphone probe, in combination with a 360° camera. The soundscape has been carried out in three Italian squares across the city of Parma. The acoustic maps obtained from the data processing detect the di-rectivity of dynamic sound sources as typical of a urban environment. The analysis of the objective environmental parameters (like loudness, roughness, sharpness, and prominence) was conducted alongside the investigations on the historical importance of Italian squares as places for social inclusivity, extended to individuals that are physically excluded from the public life. A dedicated listening playback is provided by AGORA project with a portable listening room characterized by modular unit of soundbars.
