Hearing aid and signal processing device for a hearing aid

A hearing aid (2) includes an acoustoelectric transducer (6), a signal processing device (10) and an electroacoustic transducer (14). The signal processing device (10) has a flexible printed circuit board (24) provided with electronic components (38, 40, 42, 44, 64). The printed circuit board is bent to form an approximately G-shaped stacked configuration (26). The stacked configuration (26) of the printed circuit board (24) has three horizontal limbs (30a, 30b, 30c) disposed above one another along a stacking direction (28). The outer horizontal limbs (30a, 30c) are connected to one another by a first printed circuit board section (34) and one of the outer limbs (30c) and the middle limb (30b) are connected to one another by a second printed circuit board section (36). The first printed circuit board section (34) is reinforced along the stacking direction (28) and the horizontal limbs (30a, 30b, 30c) in the stacked configuration (26) are spaced apart from one another along the stacking direction (28). 本发明涉及种
