基于智能手机平台的环境噪声监测研究

通过对传统噪声监测和评价方法的分析,借助智能手机平台开发了1套环境噪声监测系统,并以鼓浪屿为案例进行了研究。结果表明:1)利用智能手机能很好地区分不同环境功能区的噪声情况;2)能方便地获取监测点位坐标、用户感受等信息;3)能及时将监测结果分享给好友和数据中心。基于智能手机平台进行环境噪声监测,一方面降低了噪声监测的技术门槛,方便公众随时随地感知和分享身边的噪声情况;另一方面,借助公众的广泛参与,能够大大增加噪声采样点的数量,拓展数据的采集范围,形成公众环境噪声监测网。

Study on environmental noise monitoring by smart phone platform

This paper is inclined to provide a novel approach to the environmental noise monitoring,which can be taken as a new perspective for studying the environmental noise temporal-spatial distribution and environmental noise control and management.As we know,noise has now become one of the main urban environmental pollutants and the leading cause for people’s environmental complaints, which is characteristic of large spatial difference,sudden occurrence and even a threat to the regular life and feelings.It is just from the above reasons that bring about the needs to monitor and control some serious spatial and temporal noise sources.And one of such noise sources is the over-popularized intelligent devices(such as mobile phones,digital cameras,personal computers,etc.).Aiming to satisfy the need to control,we have developed an environmental noise monitoring system based on a smart phone platform by analyzing the method of environmental noise monitoring and assessment.The so-called smart phone platform is calibrated by means of a real-time noise measure instrument(HS5633T) in the noise-producing field.The platform can acquire and register the actual noise level,the monitoring time,the coordinates of the monitoring sites,in addition to people’s senses to it.And,then,the smart phone platform can record the monitoring results and let its user to share the information and data of the noise with his friends or uploaded to the digital center.Finally,we have chosen Gulangyu,Xiamen,as a study case.The results of our trial use prove that the platform could be used to distinguish the levels of different noise-producing sources, to obtain the coordinates of monitoring sites and the noise-receivers’ feelings and to share the monitoring results with his friends and the digital center in real-time instance.It is believed that the noise monitoring by using our device can both reduce the threshold of the noise monitoring level,allowing citizens to monitor and share information about environmental noise anytime and anywhere,enabling the user to increase the number of samples with public participation,expanding the scope of data collection and gradually forming a public environmental noise monitoring network.
