This presentation summarizes the work I carried out during my 18-week internship at the Hearing Aid Business Unit of Shanghai United Imaging Microelectronics Technology Co., Ltd. My tasks included various standardized measurements such as electroacoustic testing according to GB/T and IEC standards, as well as directivity, reliability, and battery voltage testing. The main focus of […]

The internship at KARL STORZ SE & Co. KG contributed to the optimization of a hardware system used in electrosurgical applications. The project focused on improving power transmission efficiency and system reliability through experimental measurements and circuit simulations. Various diagnostic methods, including impedance analysis, infrared thermography, and high-frequency signal evaluation, were applied to identify and […]

This presentation details an internship conducted at the Kärcher Sound Lab focused on minimizing structure-borne noise. The central project involved the design, construction, and validation of a custom test rig for the dynamic characterization of viscoelastic damping elements. The resulting method allowed for measurement of frequency-dependent material properties and decoupling performance. The test rig was […]
