Abstract: In a control arrangement for hearing aids or for control units coupled to hearing aids, a strain gauge is mechanically coupled to an elastically deformable or displaceable portion of the hearing aid or of the control unit coupled thereto and undergoes an elastic deformation under the influence of an actuating force input by a user, whereby the strain gauge undergoes a variation of one of its electrical values which variation is detected by a controller which provides a control signal which serves for switching between different operation modes of the hearing aid or of the control unit coupled to the hearing aid.

Abstract: A method of generating an electrical component (6) of a hearing aid electrical circuitry on a substrate (1) is suggested, wherein the electrical component is generated by material deposition and the value of a characteristic parameter of the electrical component is measured continuously during the deposition step, whereby the material deposition is terminated as soon as the measured value reaches a predetermined desired value of the monitored characteristic parameter. Thereby, a high precision of the characteristic parameters of electrical components of hearing aid electrical circuitry can be achieved without complicated trimming, tuning or adjustment elements or production steps.
