Do you need a basic air conduction audiometer? The MA 39 has been the audiometer of choice of school nurses for years. Or, for more complete testing requirements choose the MA 40 with bone conduction or the MA 41 with bone conduction, free field and speech capabilities. New Features The MA 39, 40 and 41 series audiometers provide even more functionality for your money. They come standard with a PC interface, NOAH compatibility and insert earphone compatibility. In addition the MA 41 has the capacity to drive two free field speakers without an additional amplifier. Attractive, rugged The case is built tough to withstand the bumps and knocks of daily use, yet it’s remarkably lightweight.
