The acoustic characteristics of an infant's cry can yield valuable information. Recent research, involving sonographic studies of cry sounds produced by normal and sick infants under various conditions, indicate that cry characteristics might be used in the diagnosis and monitoring of sick infants. Physio-acoustic studies of their phonation may also improve our understanding of various changes ocurring during the course of a disease.33.34 So far, studies have included small numbers of infants and most have employed some kind of pain stimulus to induce crying. As pain cries themselves have certain diagnostic features, such stimuli may blur the characteristic cry pattern of the disease. Further studies involving larger samples are required to evaluate the role of cry analysis in clinical practice.
