Use of Optical Methods for Detecting Low Frequency Sounds

This paper is a continuation of our studies related to the use of optical methods and optical communication fiber and wireless systems not only as a communication channel, but also as a network of sensors offering information. This type of information is generated by external influencing factors in the complex infrastructure of modern cities. One of these factors we have focused on is noise monitoring. This paper will consider an optical method based on wireless optical and fiber optic systems for monitoring and detecting low frequency sounds.
