[Experience in developing devices for medical use exemplified by the electronic stethophonoendoscope].

The paper describes the use of the expert's error technique to provide evidence and pool medical specifications for an electron amplifying stethophonoendoscope, a medical diagnostic device. It illustrates the impact of variations in amplitude-frequency responses (AFR) on the auscultation properties of the devise. An AFR variation of only 10-12 dB can distort sound perception at auscultation. The results of development of the electron stethophonoendoscope indicate that the correct choice of criteria for expert's estimates allows the device's specifications to be worked out with simultaneous simplification of testing procedures.
