Volker HohmannTag der Disputation: 17.12.2008iiAbstractPeople with hearing impairment have great difficulties communicating in noisy and rever-berant environments. They usually require a higher signal-to-noise ratio (SNR) to achievethe same listening performance as normal hearing people. But even for normal hearingpeople a noise reduction is desirable in these environments, especially when using moderncommunication systems such as mobile phones, handsfree devices, or teleconferencing sys-tems. Hence, the development and evaluation of noise reduction algorithms is an activefield of research. To achieve the maximum performance and subjective benefit, these al-gorithms generally need to be evaluated with objective measures that should be based onauditory models in order to predict human perception as closely as possible. The currentdissertation contributes to this field by adding yet another dimension to the problem -binaural hearing (i.e.
