Abstract: A system, method and computer program are configured to interactively assist a user in evaluating and/or configuring a hearing aid. The system is equipped with a display element, with an input unit and with a processing unit. The environmental situations are shown on the display element. Based on a user input, a selected section of the environmental situation is determined and highlighted. A specific hearing situation is presented on the basis of the selection made by the user. An evaluation scale is displayed, allowing the user to enter a hearing value for a self-assessment of his hearing ability for the specific hearing situation, and the hearing value entered by the user is recorded. The above steps are repeated and hearing values are recorded for different specific hearing situations. Based on the hearing values entered by the user, setting values for the hearing aid are determined.
