Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The description and the acoustic analysis of baby's cry can allow healthcare professionals to better adapt their care during the first months of life.
Thanks to an objective analysis method as acoustic analysis, the particularities of the first cry should provide us information on the quality of adaptation to ambient air life.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The description and the acoustic analysis of baby's cry can allow healthcare professionals to better adapt their care during the first months of life. Aiming for this objective, many studies have already been carried out on infants crying in the first months of life, in order to better understand their significance (pain, discomfort, hunger) and the mechanisms of recognition and discrimination by parents or listeners. Various techniques are promising to characterize the acoustic space of cry (maximum frequency, intensity, harmonics, duration…).
However, few studies have investigated the acoustic characteristics of the first cry of life in the delivery room. Its intensity and characteristics are closely related to the laryngeal anatomy and respiratory capacity. Thus, a vigorous cry with its own acoustic characteristics could be the witness of a good adaptation to extra uterine life, while a weak or plaintive cry should warn the caregiver on difficulties in this adaptation.
Thanks to an objective analysis method as acoustic analysis, the particularities of the first cry should provide us information on the quality of adaptation to ambient air life.
The investigators hypothesize that the acoustic characteristics of the first cries of newborns recorded at birth are correlated with the criteria of extra uterine life adaptation (Apgar score, pH and lactates collected from the umbilical cord), with the respiratory score (Silverman) and with the early neonatal outcome (transfer to the intensive care unit).

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
New born
New born population aged 37 Weeks of Amenorrhea (SA) to 42 Weeks of Amenorrhea (SA) will be included. Their cries will be longitudinally registered.
newborn cries
Their cries will be longitudinally registered from the age of birth until the first 15 minutes of birth using an automatic record device: Recorder ZOOM H4N.
The wav-sized files obtained from each recording will then be analyzed indiscriminately via an acoustic processing script created for the PRAAT software® by the post-doctoral fellows of the ENES laboratory (Sensory NeuroEthology Team) on the site of the Faculty of Sciences of Saint-Etienne.
