Beschreibung
Zusammenfassung:	A hearing aid (100) configured to control the generation of relaxing sound comprises 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; 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 a selected threshold value, means (102) for adding the processed electrical relaxing sound signal to the electrical audio 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).
