System introduction: auditory assessment system is to evaluate the hearing threshold and speech recognition ability of patients through quantitative assessment and functional assessment, which fully reflects the practical assessment criteria for hearing disability. Guidance animation is provided for each step of the system operation. Human-computer interaction can be completed by touching the system operation. After the completion of the test, the evaluation result report form and hearing curve of the left and right ears, as well as the evaluation scale for the hearing-impaired and the recognition rate and threshold of the tested object are generated.

Scope of application: it is applicable to all kinds of hearing impaired people, and can be used in rehabilitation departments of major hospitals, ent, children's hospitals, rehabilitation institutions of disabled persons' federations at all levels, special education institutions at all levels, and rehabilitation institutions for all kinds of special children. System function parameters:

This system tests the hearing threshold and speech recognition ability of the subjects through quantitative evaluation and functional evaluation. The system includes the hearing evaluation system, filtering compound tone, speech frequency analysis, auditory frequency simulation and the whole process monitoring system of rehabilitation effect.

(1) auditory orientation and tone resolution;

(2) auditory quantity and function learning, providing phonetic balanced auditory discrimination exercises;

(3) functional evaluation of pronunciation, words, phrases, short sentences and selective listening;

(3) listening and understanding of single, double and three conditions;

(4) initial vowel recognition based on phonetic balance and phonemic contrast;

(5) quantitative assessment of pure tones, trilling tones, filtered compound tones, etc

(6) provide multiple types of real background noise simulation

(7) filter compound tone: filter compound test tone with clear main frequency characteristics can be produced;

(8) whole-process monitoring system for rehabilitation effect: manage the data of the auditory assessment system module, and monitor the whole rehabilitation process of trainees.

(9) dual-screen display technology: based on the unique split screen function design, the system realizes the dual-screen function of displaying different contents on different screens through the software multi-window interactive control mechanism; The teacher is the main control screen, and the trainees are the operation control screen with touch function. A monitoring window is provided on the main control screen to facilitate the teacher to observe the trainees' reactions in real time and control the evaluation process. At the same time, it can also avoid all kinds of emotions that are not conducive to the evaluation caused by the trainees' gaze or observation of the evaluation results, and clearly understand the trainees' real-time evaluation situation.
