said user input typically one or more audio processing parameters which can be stored in parameter storage unit 16 are selected and adjusted in dependence of said user input in order to get user 50 acquainted with adjustable audio processing parameters of hearing system 1 in particular with those which can be adjusted using first user interface 12 in particular user controls 13 and 14 a method for improving the user 39 s ability to make use of these adjustable audio processing parameters can be carried out by means of arrangement 1 for carrying out such a method storage unit 8 comprises data representative of audio signals 9 which are representative of test sounds control unit 18 controls storage unit 8 signal processing unit 4 and sound generating unit 2 in such a way that test sounds are played to user 50 as signals 6 to be perceived by user 50 for example firstly a first test sound is played to user 50 then a second test sound is played to user 50 said second test sound is e g a modified version of said first test sound preferably said second test sound is obtained by feeding the same audio signals to signal processing unit 4 as are used for generating said first test sound while differently processing these audio signals in signal processing unit 4 due to differently adjusting at least one audio processing parameter and converting the so obtained audio signals in sound generating unit 2 into perceivable signals 6 it is nevertheless also possible to have data representative of audio signals representative of first and in addition data representative of audio signals representative of second test sounds stored e g in storage unit 8 if e g said.
