A bone conduction screening test was developed utilizing frontal bone oscillator placement. One hundred and fourteen preschool children were tested using a pure-tone air-conduction screening procedure, an impedance audiometry screening procedure (automatic tympanometry and ipsilateral reflex stimulation at 1000Hz), and the unoccluded bone conduction screening test. Unoccluded frontal bone conduction testing produced screening results that were not significantly different from results obtained utilizing impedance audometry.
