The distributed acoustic sensing system includes an optical fiber, a light source to inject light into the optical fiber, and a photodetector to sample a DAS signal in each section of one or more sections of the optical fiber resulting from two or more points within the section on the optical fiber over a period of time. The system also includes a processor to process only a low frequency portion of the DAS signal to obtain the acoustic levels at each of the one or more sections on the optical fiber over the period of time, the low frequency portion of the DAS signal being less than 10 Hz."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Distributed acoustic sensing using low pulse repetition rates","description":"A distributed acoustic sensing system and a method of obtaining acoustic levels using the distributed acoustic sensing system are described.
