Problem being addressed
Newborn cries can be influenced by the physiological and neurological state of the child. Information about the source of the newborn’s discomfort, which could be benign or indicative of a serious health problem, can be collected from the newborn’s cries. Diseases, infections, or deformities can change an infant’s cry by affecting the central nervous system, respiratory organs, or oral cavities. It has been shown that infants with particular diseases produce cries with certain consistent attributes (Alaie, 2012). Identifying health issues in infants in low-resource settings is difficult due to a lack of diagnostic equipment. It is also especially important because the infant is less likely to have regular access to medical care and screenings during childhood, so health problems are likely to go untreated for long periods of time.
Detailed description of the solution
The non-invasive cry diagnosis system will use computer acoustical analysis of newborn cries to detect serious medical conditions. The cries of 120 healthy and sick newborns were analyzed to identify diagnostically relevant acoustic characteristics. The next step of the development of the cry diagnosis system is to analyze a larger pool of infants in order to expand the scope of this device and the conditions it can detect. The device will also incorporate a software-based diagnostic tool that can interpret recorded cries to help neonatologists detect specific pathologies affecting newborns. This device will be especially useful in low-resource settings because it will allow healthcare workers to identify the detect health problems in newborns noninvasively immediately after birth so that treatment can be given or further investigation can be done, if necessary.
