The impact of mechanical connections between two plates on sound transmission is well-known. However, there is still a need for thorough scientific investigation into this phenomenon. Analyzing the influence of mounting elements on sound transmission can lead to effective reduction of sound propagation and improvement of partitions' sound insulation. The complexity of studying impact sound transmission through junctions arises from the various methods of connecting two parallel plates. Factors such as the number and arrangement of connecting elements, as well as the use of line or point connectors, can significantly affect sound transmission between a massive and lightweight plate. This study focuses on the influence of stud elements and the number of connecting points on the lightweight plate. An impact hammer was used to excite the massive plate, and frequency response functions were calculated for several points on both plates. The results were analyzed and compared to the theoretically derived transmission function for the investigated structure.
