A cordless phone was connected to a VoIP network on the other side of the connection. 18 test subjects, expert and na{\"i}ve participants, evaluated various aspects of conversational quality, including listening quality, listening effort, double talk impairment, echo interference, interactivity and overall quality (as outlined in DAGA 2024). In the same scenario, two artificial head and torso simulators (HATS) were used to play back and record so-called pre-recorded conversations (PRC). The PRC included single talk sequences in both directions, as well as speech parts where both voices interact and are talking at the same time. The binaural recordings at both ends (HFT user, cordless phone user) were then assessed and rated by 32 na{\"i}ve test subjects in a third-party listening test (TPLT) using the same quality aspects as in the CT. The great advantage of a TPLT compared to a CT is the much lower effort to set up and control the conditions. The auditory results of both test designs are presented, discussed and compared in terms of each quality dimension}, language = {en} } @inproceedings{HochbruecknerLangerWinkelmannetal., author = {Hochbr{\"u}ckner, Benedikt and Langer, Felix and Winkelmann, Erik and Spiertz, Martin and Zink, Markus and Steiner, Thomas and Kr{\"a}tzschmar, Karsten}, title = {Application of a Cluster-Algorithm for Partial Discharge Analysis at DC Voltage Under Practical Conditions}, doi = {10.1049/icp.2022.0037}, language = {en} } @incollection{HochbruecknerSpiertzKuechleretal., author = {Hochbr{\"u}ckner, Benedikt and Spiertz, Martin and K{\"u}chler, Andreas and Zink, Markus and Steiner, Thomas and Winkelmann, Erik and Kr{\"a}tzschmar, Karsten}, title = {Digital Filtering Methods for Interferences on Partial Discharges Under DC Voltage}, isbn = {978-3-030-31675-4}, doi = {10.1007/978-3-030-31676-1_53}, pages = {560 -- 571}, language = {en} } @inproceedings{HochbruecknerKuechlerSpiertzetal., author = {Hochbr{\"u}ckner, Benedikt and K{\"u}chler, Andreas and Spiertz, Martin and Kr{\"a}tzschmar, Karsten and Zink, Markus}, title = {Comparison of Algorithms for Clustering of Partial Discharge Signals under DC Voltage}, doi = {10.1109/ICHVEPS47643.2019.9011062}, language = {en} }
