To date, many subjective evaluation methods for measuring the performance of audio systems have been published. Most prominent examples originate from recommendations of the International Telecommunication Union, namely BS.1534, BS.1116, and P.800. Typically, in such evaluation methods, assessors rate audio quality-related attributes of stimuli processed by audio systems under test. These audio quality-related attributes are of perceptual nature and, therefore, are not expected to involve any personal preferences, feelings, or emotions regarding the used test material. Since customer decisions are not purely based on audio quality-related aspects in many real-world scenarios, these subjective evaluation methods are of limited use to indicate whether the audio systems under test will be appreciated by potential customers. In this work, a new listening test method is presented in which participants rate the so-called overall listening experience (OLE). In contrast to previous subjective evaluation methods, the participants are explicitly asked to take everything into account that is important to them when rating the test material. Thus, the results of the proposed method indicate whether the provided technical audio quality of the audio systems under test significantly affect the participants’ overall listening experience, or Quality of Experience (QoE). ; Bis heute wurden bereits zahlreiche subjektive Evaluierungsmethoden für Audio-Systeme veröffentlicht. Zu den bekanntesten Beispielen zählen die Methoden aus den Empfehlungen der Internationalen Fernmeldeunion (ITU), wie BS.1534, BS.1116 und P.800. Üblicherweise werden in diesen Evaluierungsmethoden Audio-Systeme ausschließlich hinsichtlich ihrer Audioqualität bewertet. Evaluierungsteilnehmer blenden daher ihre persönlichen Präferenzen sowie sonstigen Empfindungen und Emotionen während einer Evaluierung aus. Eine Vielzahl von alltäglichen (Kauf-)Entscheidungen für Audio-Systeme wird allerdings nicht ausschließlich auf Basis der Audioqualität getätigt. Wenn ...
