SUMMARY:Ibe: Measurement of Structure-Borne Sound Excitation by Headphones
DESCRIPTION:Bone conduction has a big impact on the perception of the human being. Even though headphones are used by a billion of people around the world\, it was yet not analyzed if the headphones excite structure-borne sound. Structure-borne sound they could cause bone conduction or cartilage conduction and interfere with the perception of the user. This thesis aims to take first steps in the characterization of the stimulated vibrations of headphones. An Laser Doppler vibrometry is used to measure the velocity on a headphone attached to an artificial ear on an acoustic test fixture.\nAdditionally\, the acoustic test fixture is also used to measure the sound pressure level. The laser is targeted on the headphones from different directions and angles\, to get a three-dimensional impression of the motion. By measuring the sound pressure and the velocity of the headphone parallelly\, the stimulated vibration is getting analyzed in a three-dimensional and in an energetic point of view. Based on the measurement results\, the excitation and the vibration’s dependence on the boundary conditions will be discussed. \nMelden Sie sich hier an um die Einladung zu dem Vortrag per E-Mail zu erhalten.\nRegister here to receive the invitation to this talk via E-Mail. \nZoom-Meeting-ID: 932 2771 2278\nPasswort: 767129

SUMMARY:Chen: Internship with Huawei Deutschland
DESCRIPTION:From October 2019 to March 2020\, I worked as an intern at Device Vodafone GTM Department in Düsseldorf Huawei. Huawei Technologies Co.\, Ltd.\, whose headquarter is located in Shen Zhen China\, is a multinational tech-communication company that provides telecommunications equipment and sales of consumer electronics products including smartphones. My responsibilities are mainly as a Test Engineer\, cooperating with Chinese R&D team as well as with Vodafone Lab to solve the live testing related issues. I also support on in market device lifestyle maintenance\, including test presentation and status reporting. \nMelden Sie sich hier an um die Einladung zu dem Vortrag per E-Mail zu erhalten.\nRegister here to receive the invitation to this talk via E-Mail. \nZoom-Meeting-ID: 932 2771 2278\nPasswort: 767129
