Abstract

The invention discloses a network type multi-channel hearing detection and judgment system. The system comprises a portable host, a network exchanger and a multi-channel audio signal unit, wherein the portable host is connected with the network exchanger; and the network exchanger is connected with the multi-channel audio signal unit. Compared with the prior art, multiple sounds are synthesized and mixed through an FPGA unit and a DDS unit; support of an Ethernet interface is added; equipment and the network exchanger realize Ethernet communication, so that Ethernet-based data transmission and command control become reality; a low-noise power supply is configured for reducing a signal-noise ratio of a whole signal; by adding drivers of multiple outputs in hardware, signal conditioning and driving effectively solves the problem of simultaneous hearing detection of multiple persons, and automatic test, automatic judgment and test result quantitative printout functions are realized; personnel can be trained and assessed according to specific hearing requirements; and the system is moderate in overall manufacturing cost and low in maintenance cost, and is simple and convenient to use, and the personnel do not need to be professionally trained.

Description

Technical field [0001] The invention relates to the technical field of hearing detection, in particular to a network-type multi-channel hearing detection and evaluation system. Background technique [0002] The current hearing test methods are mainly divided into: subjective test method and objective test method. The subjective test method is based on the result of the subject's subjective judgment; the objective test method does not require the subject's subjective reaction, and the result is reliable, but the equipment is expensive and the test technology requires high. At present, there are mainly the following problems with the objective test method: 1) Professional hearing equipment is expensive, only pure tones can be tested, and the maintenance cost is high; 2) The test technology requires high; 3) The test method results rely on manual labor, which is prone to errors and cheating; 4) Every This test can only detect one object, and a professional tester is required, which...
