Most of the hearing disorders might be treatable in the early age of life. There are variant methods to test the hearing abilities of an infant; still none of them cover the whole auditory system by itself. Thus a comprehensive audiometry with high hit probability is required. Crying is the first tool of communication for an infant. Emotions, state of health or several organ functions can be obtained from it. Normally, an auditory feedback works between the produced sound and the brain. When this feedback has problems, crying may differ from the original one. Authors are to find these differences by acoustic analysis. This paper deals with acoustic features of the infant cry in order to detect hearing impairments.
