Portable audiometry and calibration device and audiometry and calibration methods

Abstract

The invention provides a portable audiometry device and audiometry and calibration methods. The portable audiometry device comprises a computer sound card, a double-channel headphone and a listening curve generation module. The computer sound card is used for control of sound card output to send standard sound signals with specific frequency and sound intensity. The double-channel headphone is used for transmitting the standard sound signals sent by the computer sound card into ears to realize interactive air-conduction audiometry with a controlling effect. The listening curve generation module is used for drawing listening curves of people under examination. The double-channel headphone is connected with the computer sound card through and adapter. The adapter comprises a dual-core audio cable, four PG7 copper joints, an audio socket with the diameter of 6.5 micrometers and a case, wherein one end of the dual-core audio cable is connected with an RCA output port of the computer sound card, the other end of the dual-core audio cable is connected with two PG7 copper joints fixed at one end of the case, the rest PG7 copper joints are connected with the audio socket, with the diameter of 6.5 micrometers, disposed at the other end of the case, and the input end of the double-channel headphone is connected with the audio socket.

Description

technical field [0001] The invention relates to an audiometry device using a notebook computer sound card and a professional earphone, which meets the needs of medical examination. Background technique [0002] At present, most of the audiometry examinations in the ENT department of the hospital require professional audiometry rooms and audiometry equipment, which are expensive and not portable, especially not conducive to the screening and monitoring of patients' hearing at any time. [0003] Traditional audiometry examinations are usually done in an audiometry room, and the existing audiometry examination methods are not portable, so it is extremely inconvenient for patients to perform audiometry examinations, especially the daily monitoring of patients with hearing fluctuations is not easy to achieve. Contents of the invention [0004] The object of the present invention is to provide a portable hearing test and calibration device and method to overcome the above proble...
