A hearing aid (100) configured to control the generation of relaxing sound comprising an acoustical-electrical transducer (101), means (105) for deriving a characteristic value from the electrical audio signal, comparator means (106) configured to compare the derived characteristic value with a selected threshold value, switching means (107) configured to select a threshold value, relaxing sound generating means (108), first signal processing means (109) adapted for increasing or decreasing the level of the electrical relaxing sound signal as a function of the control value and the selected threshold value, means (102) for adding the processed electrical relaxing sound signal to the electrical audio signal hereby providing an electrical input signal, second signal processing means (103) configured to amplify the electrical input signal and an electrical-acoustical output transducer (104). The invention further provides a method of controlling the generation of relaxing sound in a hearing aid (100).
