4 Instrument Description The HT Wizard is a pure-tone air conduction microprocessor screening audiometer. Designed in an attractive portable compact case, the HT Wizard includes state-of-the art software and electronics. Typical users include military organizations, large industries, and medical offices, which screen individuals for hearing loss or acuity. With proper operation, maintenance, and scheduled calibrations, the HT Wizard provides reliable and repeatable results. The HT Wizard determines hearing threshold levels using the proven Hughson- Westlake Test Paradyne, which allows the operator to screen subject s for shifts in hearing acuity. Use the audiometer to record the subject s current threshold, which may be affected from day to day noise exposure, colds, sinus infections, or other problems. The audiograms obtained from HT Wizard may be used to maintain records for the subject and for the company administering the test. This helps the health care professional evaluate and prevent major hearing problems. With the use of an optional Electro-Acoustic Ear (OSCAR), for daily comparisons to acoustic ear baseline, the operator can verify calibration. Terminology HT Wizard as used through out this operation manual refers to the HT Wizard Ultra audiometer. Medical Disclaimer: Testing, as referred to in this manual, is the screening procedure used to establish thresholds (hearing levels) and is in no way trying to diagnose, monitor, or treat any medical problem, disease or injury. If a problem is suspected, the subject should be referred to an audiologist or medical doctor for evaluation. 2
