Automatic sound giving method for test sound duration

The invention discloses an automatic sound giving method for test sound duration. The method comprises the following steps that 1, a hearing test chart is input to hearing test equipment; 2, test sound duration is determined according to a hearing test type; 3, duration information is fed back to a processing center; 4, the processing center feeds a processing result back to a sound output device; 5, the output device outputs a test sound with the corresponding duration. An operator judges the hearing test type according to the hearing condition of a patient and determines the test sound duration according to the hearing test type, and the processing center controls the sound output device to output the sound with the corresponding duration by processing the duration information. In this way, the test sound duration is controlled by the processing center, the test sound with the corresponding time is played automatically, and the test sound does not need to be controlled according to the time by manually clicking on a button; therefore, the test sound with the accurate duration can be output, testing of different hearing test items is convenient, and the accuracy of test results is improved.
