Zusammenfassung:	A rigorous observational procedure is described for estimating the detectability of auditory signals in the first few months of life. This procedure, a modification of the observer-based psychoacoustic procedure, generates a bias-free estimate of auditory sensitivity and avoids some of the potential problems associated with alternative techniques. Data from infants 1.5, 2.5, and 3.5 months of age revealed orderly improvement in performance as a function of increasing signal intensity and age. Finally, the way in which the procedure can be used to screen infants for auditory deficits is described.
