Abstract:
A method for audiological screening of infants and newborns comprising:a. generating one or more stimuli with acoustic transmitters in each ear canal of the infant or newborn,b. collecting any transient evoked and distortion product otoacoustic emissions generated by the cochlea in each ear canal in response to the stimulus with microphone means for generating a frequency mixed product electronic signal,c. inputting the frequency mixed product electronic signal from the microphone means and the stimulus frequencies into a computer processor,d. amplifying the frequency mixed product electronic signal with an input amplifier,e. computer analyzing the frequencies of a measured accoustic signal by means of a frequency and phase analyzer to separate the different frequencies and phases from one another,f. 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, andg. displaying if the otoacoustic signal response is or is not statistically significant on a computer display.
