Hearing aid with a capacitor having a large capacitance

   
   

A hearing aid is provided having a capacitor with a large capacitance coupled in parallel with the energy source for transient current supply. The operating period of the battery is prolonged compared to prior art digital hearing aids. Further, the smaller variations in supply voltage lead to less distortion of the output signal of the hearing aid signal processor. In a hearing aid with a telecoil, a well defined current path for the current transients generating the high magnetic fields picked up by the telecoil is established. This facilitates the design of a compensating current path that is substantially independent of battery type and position.
