Abstract

This study aims to investigate the sound transmission path of floor impact noise in multi-story buildings through acoustic visualization. Floor impact noise was measured in a multi-story building with the 32-channel spherical microphone array. The floor impact noise was generated by the impact ball in a living room. A microphone array was located at the center of the receiving room. Plane wave decomposition and adaptive beamforming technique, such as Minimum Variance Distortioneless Response (MVDR) spatial spectrum estimate, were used in order to detect the sound transmission path in the room. Directional impulse responses (DIRs) were generated and the sound level was visualized. Through the acoustic visualization, sound transmission path was discussed based on the contribution of room components such as a ceiling, walls and windows on the floor impact noise.
