Sound intensity vectors near the aperture of an acoustical coupled volume system

Sound intensity is crucial for describing the flow of sound energy in spaces. This work utilizes an intensity sensor (Microflown®), measuring sound intensity distributions near the aperture of a real-sized coupled volume system. The experimental measurements using the Microflown® sensors facilitate detailed analysis of the intensity vectors near the aperture when the system is under different conditions. It provides an efficient way to visualize sound energy exchanges between the primary and the secondary room, which can be beneficial for further analysis and validation, leading to advanced understanding of acoustics in coupled volume systems. This talk discusses the measurement conditions; the analysis method and visualization of the sound intensity vectors distributions over an extended area near the aperture.
