[origin: US4716985A] The housing of the hearing aid comprises a distal, bead-like head part having a planar face on which an arched face plate is seated and comprises a proximal, thinner tail part. The angle alpha between the normal of the planar face and the longitudinal axis of the tail part lies in the range of 135 DEG through 142 DEG , preferably at 140 DEG , in a first longitudinal plane through the housing and a corresponding angle beta in a second, perpendicular longitudinal plane through the housing lies in the range from 12 DEG through 17 DEG , preferably at 14 DEG .
