The sound is characteristic to its source, to the circumstances during the propagation, and to the perceptible capacity of the observer. The classical question in the noise control is true also in the present; if the received sound is disturbing or not? On the other hand, give the troublesome noise carried sound signals any information to the observer, or they are fully unwanted? The case study is a new approach to analyze the infant cry. The infant cry seems to be a typical noise as a social point of view, but it is a very important information source in medicine, in infant care and in the family. Since the last few years we've been involved in traditional medical researches in our country to obtain the cry signal of young infants. The acoustic analysis of the cries produced important aspects of explanations. Infant cries may refer the life demands, different illness symptoms and moods of the investigated infants. Our latest research results give possibility to elaborate a rapid method for hearing screening among the newborn infants.
