基于智能手机Phyphox软件的声源定位

Sound Localization Based on Phyphox Software of Smartphone Phyphox

设计了一种基于智能手机的声源定位方案,利用多部智能手机的麦克风和Phyphox软件中的声学秒表功能来实现对未知声源的定位探测。相比较于其他测量声音定位的方法,该实验设计充分利用了智能手机的潜能,利用Phyphox软件将手机作为传感器节点进行定位,提出一种新颖的定位方案:利用智能手机软件Phyphox采集和处理声音信号,计算声音信号到达手机麦克风的时间差,利用时间差计算出声源目标在二维空间中的坐标位置。

A sound source location scheme based on Smartphone is designed,which uses the microphone of smartphones and the acoustic stopwatch function in Phyphox software to realize the location detection of unknown sound sources.Compared with other methods for measuring sound location,this experimental design fully utilizes the potential of smart phones,uses the Phyphox software to locate the mobile phone as a sensor node,and proposes a novel location scheme:use the smart phone software Phyphox to collect and process the sound signal,calculate the time difference between the sound signal and the microphone of the mobile phone,and then use the time difference to calculate the coordinate position of the sound source target in the two-dimensional space.
