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
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.
