This pure tone air conduction Audiometer manufactured by TREMETRICS was designed primarily for use in determining hearing threshold levels in comparison with standard reference threshold levels. The Audiometer is a screening device that if properly operated, maintained, and calibrated will allow the operator to screen subjects for shifts in hearing acuity. The Audiometer is used to record the subject’s current threshold, which may be affected from day to day by noise exposure, colds, sinus infections, or other problems
