In the frame of the HearCom1 project five promising signal en-hancement algorithms are validated for future use in hearing instru-ment devices. To assess the algorithm performance solely based on simulation experiments, a number of physical evaluation mea-sures have been proposed that incorporate basic aspects of normal and impaired human hearing. Additionally, each of the algorithms has been implemented on a common real-time hardware/software platform, which facilitates a profound subjective validation of the algorithm performance. Recently, a multicenter study has been set up across five different test centers in Belgium, the Netherlands, Germany and Switzerland to perceptually evaluate the selected sig-nal enhancement approaches with normally hearing and hearing im-paired listeners. 1.
