Abstract

The invention provides a pure tone audiometric system formed by utilizing a digital sound card. The pure tone audiometric system includes an air conduction earphone, a bone conduction earphone, a loudspeaker, a transponder and link cables. The pure tone audiometric system is characterized in that: a computer and a USB sound card are also included; the air conduction earphone, the bone conduction earphone, the transponder and the loudspeaker are connected with specified sockets of the USB sound card by the link cables, respectively; the USB sound card is mounted on a USB interface of the computer to act as a signal output device. Compared with the prior art, the pure tone audiometric system of the invention is overwhelmingly more competitive in production cost than traditional analog electric audiometric apparatuses; and as the software is possible to be produced in quantity, the whole system has good extensibility and is allowed to do more abundant designs in functions and develop more user-friendly interactive interface.

Description

technical field [0001] The invention relates to a medical device, in particular to a pure tone hearing test system formed by using a digital sound card. Background technique [0002] Existing audiometer instruments use single-chip microcomputers and electronic circuits to form separate analog hearing equipment, and the effect of these existing analog hearing equipment mainly depends on the production of hardware, and its components require precision and high prices. The upgrade of the function is very limited, and there is no audiometer that outputs signals through the computer sound card and uses software as the main control. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a pure tone hearing test system formed by using a digital sound card, which can effectively reduce the manufacturing cost, has more functions, is more convenient to use and is humanized. [0004] The technical problem to be solved by the pres...
