The invention relates to the technical field of traffic indication, in particular to a sound prompt device and method capable of automatically adjusting volume based on environmental noise, environmental noise in a certain time period is collected in real time through an environmental noise detection module, the average value of noise in the time period is calculated, the noise collection precision is higher, and the sound prompt effect is better. And meanwhile, the main control module obtains the size of the output volume according to the average value of the noise, so that the played content is more easily heard by waiting people. The environment noise detection module collects noise in real time, and noise pollution caused by the played volume is avoided. The traffic light state detection module detects the state of the traffic light in real time, plays different contents according to different states of the traffic light, reminds waiting personnel in real time, and improves the safety of the personnel. Different use scenes can be met only by setting different parameters in the parameter setting module according to different used areas.

    本发明涉及交通指示技术领域,尤指一种基于环境噪音自动调节音量的声响提示装置及方法,通过环境噪音检测模块实时采集某一时间段环境噪音并计算出该时间段的噪音平均值,采集噪音的精度更高,同时主控模块更具噪音的平均值得出输出音量的大小,达到所播放的内容被等待人群更加容易听到。环境噪音检测模块实时采集噪音,避免所播放的音量造成噪音污染。红绿灯状态检测模块实时检测红绿灯的状态,根据红绿灯的状态不同播放不同的内容,实时提醒等待人员,提高人员的安全性。根据所使用的区域不同只需要在参数设置模块设置不同的参数,能满足不同的使用场景。
