Abstract
Objective To develop a portable and quick detector for noise-induced hearing loss and sound conditioning which is suitable for airman and ground crew. Methods In the present research, the Mini2440 with ARM920T core was used as a main control board, and the UCOS minimum embedded system was used as multitask scheduler. Meanwhile, by using ADS software, the detector could write the development board program, generate the noise acquisition signal and test signal, and automatically complete the automatic hearing damage detection. Results The system could produce audio signals of stable frequency and intensity according to Diagnosis of occupational noise-induced deafness (GBZ49-2014), and realize automatic screening of hearing damage and the function of noise acquisition in a certain background. Conclusion The detector works well and has the characteristics of good stability, strong expansibility and friendly interface.关键词
