A handheld apparatus and method for comprehensive hearing testing with pass/refer results applicable for large scale neonatal screening, adult screening, or full hearing diagnostic. The apparatus contains a signal processor, integral ear probe, and remote ear and scalp probes all packaged as a single handheld battery operated device. The apparatus preferably performs a range of tests, either independently or combined: otoacoustic measurements utilizing a novel digital signal processing method for evoked otoacoustic signal processing, auditory brain stem response test, tympanometry, and otoreflectance. Algorithms for automatic test sequence, and pass/refer indication for the tests are provided.
