The Effectiveness of Audiovisual Intervention

"【Group 1】During the first three days, the researchers will provide a storybook to the father of the premature infant, and the researchers assist in recording the father's voice of the storybook in the form of MP4 recording. At the fourth day, one hour after the baby feeding, the father's voice will be played by the player to the baby, for 2 consecutive days, 2 times/day, 10 minutes/time. The baby's heartbeat, breathing and blood oxygen changes will be recorded and monitored with a physiological monitor. The recording files will be kept by the researcher.~【Group 2】 The intervention will be the same with Group 1 except the following intervention: on the 4th-6th day of the baby's birth, sleeping in the incubator, the baby's reaction behavior will be taken with a mobile phone, 1 time/day, 5 minutes/time, for 3 consecutive days, the image feedback is delivered to the father in person."
