Design And Implementation Of Hearing Aid Training Video On Demand System

Due to the use of hearing aids involves many professional and technical knowledge, how to train professional personnel to correct selection of hearing aids? And how to guide users to use hearing aids? All of these are common problems which are faced by manufacturers and sellers. The traditional methods which mainly require a large number of technical personnel, appropriate training sites, repeat the related products promotion and technology training. With the rapid development of computer network technology, network video on demand which has interactive playback mode, can save training and publicity costs, and improve work efficiency. Therefore, in order to meet the needs of enterprises technical training and product promotion, development of the training video on demand system has a great significance.In this paper, we first introduce the research background and significance of hearing aid training video on demand system. We introduce the domestic and foreign related video on demand system research status and development trend. The application architecture of the system is introduced, and the system is analyzed. System anlyses include a networking technology analysis, system hardware server selection analysis, system functional analysis. According to the demand analysis of system, we design the fuction of system. The system static model and dynamic model is established based on UML. And finally the system is implemented. Building the UML model of the system can enhance the system portability, and greatly shorten the development cycle of the system.The system can assist the enterprise to carry on the training and teaching to the relevant technical staff and ordinary users. Training contents mainly include basic knowledge of acoustics, technology of hearing monitoring, ear mold introduction, classification and principle of hearing aids, repairing and maintenance of hearing aids, SIEMENS series hearing aids. The system can provide video, audio, text, pictures, animation courseware etc. The system make relevant technical staff and ordinary users can not be limited by time and space, more play to the initiative and enthusiasm, learning to share more training teaching resources. The system can improve the enterprise training system efficiency, and greatly save the cost of technical training and product promotion.
