Fiber Optic Distributed Acoustic Sensing Technology
Rayleigh scattering -based distributed acoustic sensing (DAS) systems use fiber optic cables to provide distributed strain sensing. In DAS, the optical fiber cable becomes the sensing element and measurements are made, and in part processed, using an attached optoelectronic device.

FC interface has a buzzing sound
If you hear a constant buzzing sound from your interface, it is likely caused by a ground loop. These loops pick up electromagnetic interference. Proper grounding techniques can help cut this type of. The most common noises can happen on and off, making it hard to work with your interface. USB cables and interference from other electronic devices are often the culprits. The audio interface is the link between audio equipment and a computer or digital audio workstation, and it includes several components that optimize audio. This is a recording of the buzz on my focusrite interface naturally, and then when I put my hand on the interface or jack for my guitar. A quick on-the-spot fix is unplugging my interface, plugging it back in, closing the DAW I use to record and monitor audio (Audacity), then reopening. Shortly after entering the game (around 3–5 minutes), my entire PC would suddenly freeze completely and emit a buzzing sound; the only way to resolve it was to force a shutdown.
