Effect of Maternal Voice on Physiological Indicators and Feeding Performance
Sponsor: Acibadem University
Summary
This study aimed to determine the effect of maternal voice on physiological indicators and oral feeding performance in preterm infants. Hypothesis 1 (H1): Preterm infants who listen to their mother's voice throughout the full oral feeding process have higher oxygen saturation levels than those who do not. Hypothesis 2 (H2): Preterm infants who listen to their mother's voice throughout the full oral feeding process have lower heart rates than those who do not. Hypothesis 3 (H3): Preterm infants exposed to maternal voice throughout the full oral feeding process have lower respiratory rates than those who are not exposed. Hypothesis 4 (H4): Preterm infants exposed to maternal voice throughout the full oral feeding process have better feeding maturation than those who are not exposed. Hypothesis 5 (H5): The percentage of nutrient intake in preterm infants exposed to maternal voice throughout the entire oral feeding process is higher than in those not exposed. Hypothesis 6 (H6): The feeding time of preterm infants exposed to the mother's voice throughout the entire oral feeding process is shorter than that of those not exposed. Hypothesis 7 (H7): The amount of food consumed per minute by preterm infants exposed to the mother's voice throughout the entire oral feeding process is greater than that of those not exposed.

Conditions
Interventions
Maternal voice
Mothers of the infants in the intervention group will be asked to read aloud the lyrics of a designated in a calm tone of voice in a quiet environment, and their voices will be recorded. The recorded maternal voice will then be played to the infants in the NICU using the same Bluetooth-enabled device with built-in speakers. The audio device will be placed inside the incubator or open warmer, approximately 20-30 cm from the infant. Each infant will be assigned an individual audio device, which will be used exclusively for that infant. Maternal voice playback will begin 20 minutes before morning and evening oral feedings and will continue throughout the feeding session, twice daily, for a maximum of 5 days. If the infant is discharged earlier, the intervention will be discontinued.. During the playback of the maternal voice, monitor sounds in the NICU will be minimized, and the staff will be instructed to speak quietly to maintain a calm environment.
Control Group (standard feeding )
The control group will not be exposed to maternal voice, and standard feeding procedures will be applied.
