Measurements of Room Acoustics with Two Different Methods - A Case Study

Room acoustics has always been an important study in indoor environmental science, and the investigation of its acoustical characteristics is an indispensable basis for subsequent research. In this paper, a conference room located in the engineer’s office of Treviso province was investigated. The experiments were conducted firstly with an omnidirectional microphone and a dummy head, from which the traditional values of the main acoustic parameters were collected for further data analysis; followed by a spherical array microphone and a 360° camera were utilized for the measurements that ensued, and a video of the real-time room impulse response was obtained, and numerous shots were used instead to visualize the sound reflections taking place across the entire volume.
