A method for operating a hearing device (1) that is openly coupled to an ear (4) of a hearing device user is described. The method comprising the steps of determining a momentary acoustic situation by processing an input signal of the hearing device (1), selecting a hearing program out of at least two hearing programs in dependence on the determined momentary acoustic situation, at least one of the at least two hearing programs being suitable for calm acoustic situations, and at least another one of the at least two hearing programs being suitable for noisy acoustic situations, applying a gain only above a predefined frequency limit to the input signal of the hearing device (1) if one of the at least one hearing program for calm acoustic situations is selected, and reducing noise in the input signal only in a frequency range within audible frequencies if one of the at least one hearing program for noisy acoustic situations is selected. Therewith, a remarkably better matching of the needs of mild to very mild hearing losses is obtained than with known hearing devices.
