At the same time, the inadequateness and unreliability of this means of testing the hearing of infants, children, malingerers, and persons with psychogenic deafness has been acknowledged.1The principal weakness of the conventional audiometric technique for young children lies in its dependency upon purely subjective responses and the conscious cooperation of the child.
