An audiological screening and testing method and apparatus for newborns and infants employing audiological screening via statistical phase analysis of otoacoustic emissions in response to acoustic stimuli comprising: generating one or more stimuli with acoustic transmitters in each ear canal of the infant or newborn, collecting any transient evoked and distortion product otoacoustic emissions generated by the cochlea in each ear canal in response to the stimulus with microphones for generating a frequency mixed product electronic signal, inputting the frequency mixed product electronic signal from the microphone means and the stimululs frequencies into a computer processor, amplifying the frequency mixed product electronic signal with an input amplifier, computer analyzing the frequencies of a measured acoustic signal by means of a frequency and phase analyzer to separate the different frequencies and phases from one another, computer statistically evaluating the different acoustic signal components separately by means of binomial statistics to determine whether the measured signal contains stimulus elicited components for each frequency on a defined level of significance, and displaying if the otoacoustic signal response is or is not statistically significant on a computer display.
