[Brain stem evoked response audiometry via air- and bone-conducted stimulation (author's transl)].

Brain stem potentials can be released by bone-conducted stimulation. The spectral composition of the skull vibration being generated by ton-bursts (1, 2, 4 and 8 kc) were recorded from several positions of the head. Combined acoustic stimulation via air- and bone-conduction (BERA) enables, on principle, a differentiated statement of sound conduction and inner ear components of hypacusis in infancy, analogous to conventional audiometry.
