METHOD FOR DETERMINING TIME FOR ENGINEERING COLLEGE STUDENTS TO FINISH A LESSON

摘要

FIELD: medicine.;SUBSTANCE: method involves periodically producing acoustic oscillations in bandwidth of 0.2-0.5 kHz in parallel to presenting teaching material. They are amplified to acoustic pressure level that is no more than 7% as high as auditory threshold. It is broadcasted into a lecture room where a lesson takes place. The students are considered to reach fatigue level, hindering digestion of the teaching material, if registration time increment growing longer than 4 s.;EFFECT: enhanced effectiveness in obtaining objective fatigue level estimate at lectures and practical studies.
