title: Acoustical analyses of neonates' vocalizations.
abstract: Crying and other vocalizations of normal children under the age of 3 days were recorded and analyzed. The purpose was to establish a norm, in acoustical terms, to which one could compare the cry of any given newborn of the same age. One hopes that such a template may assist in the identification of such neonates who have airway obstructions and/or inadequate neuromotor control of respiration. The data reveal two things. One is that the type of vocalization (cry or non-cry) is not relevant to the analysis. The other finding is that spontaneous vocalization (as distinguished from elicited vocalization) is satisfactory for the purpose.
