Objective: In order to observe the kinds and intensity of the working noise of Yansan Petrochemical Co. and the effects caused by the working noise on the workers＇ vestibular and auditory function. Method :The intensity and frequency of the working noise were recorded by exactolnoisemeter in the workshop. One hundred and seventeen workers were tested in routine pure-tone tested method. The SPVN and ABR were tested within fifty-one workers of all. Result:The working noise of Yansan Petrochemical Co. belongs to the broad band and steady noise. The intensity of the working noise were during 85.7～104.0 dB (A) and the main frequency were during 1～8 kHz. About 59 percent workers who exposed to the working noise had hearing loss. The most hearing-loss were in the high frequency. The hearing-loss of speech frequency were slight. Workers who have more six years standing have obviously increased hearing-loss than the workers who have less five years standing. There were significant differences the ABR thresholds and wave-interval between the tested and controlled groups. The SPVN and CP were abnormal in more than 17.4 percent workers with hearing loss. Conclusion: The working noise of Yansan Petrochemical Co. belongs to the broad band and steady noise. Working noise can lead to workers＇ hearing loss of certain degrees who exposed in the noise for a long time. Obvious correlation was not defined between the hearing-loss and the abnormal vestibular response group.

Remote monitoring has changed the traditional management chronic heart failure patients, and nurses can implement continuous care for patients more efficiently. This article reviews the concept of remote monitoring, the application and effects of remote monitoring, the role of nurses in remote monitoring of chronic heart failure, the application and supervision of remote monitoring, and the establishment of a personalized integrated management network platform for patients with chronic heart failure.
