The Research On Intelligent Detection And Treatment Of Tinnitus Integration System

In the current competitive environment and under the pressure from the surrounding deteriorate environment, people's tinnitus has become a major disease. The tinnitus curing instrument system develops rapidly in foreign countries, but slow in the domestic and not very good in clinical results. On the basis of LS-â…¢type of the tinnitus curing system developed by shanxi kanglisheng acoustic mountain, the system make a deep development.Using one channel of one board design, the system has developed a intelligent detection and treatment of tinnitus integration system with good human-computer interaction interface on the base of the national standards and the therapy of tinnitus masking. The system can issue a pure tone, tone twitter, narrowband noise and natural sound of the voice signal, and can adjust the loudness and frequency of the signals with some accuracy. The voice signals use the digital deal and later in the process of the digital-analog conversion by the use of the IDA0H of the 8051F330. The system consist of the multi-level adjustable attenuation networks using for intensity attenuation, power driver circuit, resistor matching circuits, load headphones, power supply circuit such some function modules. The paper uses the method of Modular design. And take a series of anti-interference measures. The entire system uses software to streamline the hardware circuit in order to improve the reliability and accuracy the same with reducing costs.The PC software uses LabWindows/CVI as the method to design the software, and take the advantage of the database technology to store and management call the user files.Developed a more standardized communication protocol, the paper can display the real-time of the parameters set up by the doctor. Through the CAN bus the signal parameters can be transmitted to the next-bit machine to control its implementation of the corresponding operation. The system can mask the curve mapping and store the treatment parameters by the feedback information obtained by the MCU external interrupt.At the debug the system and experimental stage, the system has good communication and the simple and convenient operation. After China Metrology Institute of Science and Technology in Beijing test, the largest sound of the pure tone and narrow-band noise has reached the national standard. And also it can be carried out for the 1dB step intensity control. The frequency error is smaller, the system can store a dozen of natural sounds and make them output...
