Energy distribution in the spectrograms of the cries of normal and birth asphyxiated infants.
This paper describes the distribution of energy and energy variance with frequency in the cries of normal and birth asphyxiated infants recorded within eight days of delivery. Single-variable statistical analysis suggested that asphyxiated infants have their cries shifted up in frequency compared to control infants, up to a frequency of 10 kHz.
