Pure-tone audiometry apparatus capable of automatic shielding

摘要

The present invention relates to a pure-tone audiometry equipment. And more particularly to a pure tone hearing test device including an automatic shielding function. With it is possible by using the pure-tone audiometry equipment, and automatically executes the bone conduction audiometry and air conduction audiometry, it is possible that, if necessary, to automatically perform shielding test. Thus, without the assistance of others, the user is able to obtain an accurate pure tone hearing thresholds. The pure tone hearing test device of the present invention, that while performing the masking automatically and accurately performing pure tone audiometry is possible, that they do not require the assistance of hearing nurses and doctor. Thus, using a pure tone hearing test device, the user is testable hearing easily can be made early detection and prevention of hearing loss becomes possible, and take quick measures against hearing loss it becomes.
