From Texas earthquake monitoring to lunar surface deployment, Silicon Audio instruments perform in environments where failure isn’t an option. Each product line represents years of advanced R&D, proven in mission-critical applications from DOE nuclear monitoring to NASA’s Artemis III program.
Engineering excellence. Uncompromising performance. Limitless applications.
Silicon Audio’s analog optical sensors integrate proven geophone mechanics with breakthrough optical interferometry, delivering scientific-grade sensitivity in rugged, field-ready packages. Born from revolutionary microphone designs, our sensors eliminate the traditional trade-offs between sensitivity and dynamic range, capturing the full spectrum of critical ground motion observations in a single instrument to bridge weak- and strong-motion applications.
Our digital sensor systems combine precision optical sensing with embedded Linux processing, delivering turnkey monitoring solutions that leverage our innovative double-digitization architecture, integrated with any of our sensors with industry-leading dynamic range. Built-in intelligence handles everything from system power to GPS timing to real-time, low-latency data delivery, while modular expansion enables multi-sensor monitoring stations.
From lunar surface deployment to deep-ocean monitoring, Silicon Audio develops world-class custom solutions that expand seismometry far beyond traditional applications. Our unique engineering team leverages decades of optical sensing expertise and instrument design to create solutions that perform in the most demanding environments, whether monitoring nuclear treaty compliance or exploring planetary interiors.
Silicon Audio is supporting Texas’s critical TexNet program, the most advanced state-run seismic monitoring system in the country, funded with over $4.5 million to deploy nearly 100 seismometer across Texas to monitor earthquake activity linked to oil and gas operations. Our sensors are part of a statewide grid that provide real-time earthquake detection down to magnitude 1.5 and enabling researchers to distinguish between natural and induced seismic events. This critical infrastructure helps state regulators, industry, and communities make data-driven decisions about seismic risks, representing a paradigm shift in earthquake monitoring and analysis capabilities for the energy-rich regions of Texas.
Silicon Audio collaborated with the University of Arizona and the University of Maryland to operate a temporary seismic array in Greenland as part of a NASA-funded “icy worlds” project. We worked with UofA and UMD to deploy and maintain a seismic array, demonstrating our sensor’s capabilities to operate in harsh conditions without compromising on data quality.
Silicon Audio is a key team partner with University of Arizona and Goddard Space Flight Center to supply seismometers to Lunar Environment Monitoring Station (LEMS), one of the first three payloads to be a part of NASA’s Artemis III mission. We leveraged our deep history in transforming optical interferometry from laboratory curiosity into ruggedized instruments deployed in Earth’s harshest environments, making them the go-to sensor supplier for this key NASA mission.
Silicon Audio’s optical seismometers are currently deployed by Los Alamos National Laboratory for critical nuclear nonproliferation monitoring research, leveraging our sensors’ ultra-low noise performance and high dynamic range to detect and analyze seismic signatures from potential underground nuclear tests. This collaboration represents a cornerstone application where our precision optical technology and industry-leading omnitilt sensor capabilities directly support national security objectives, demonstrating how breakthrough sensor performance translates to enhanced monitoring capabilities for one of the nation’s most sensitive detection missions.
Silicon Audio has partnered with Subsea Data Systems to revolutionize underwater seismic monitoring by integrating our optical seismometers into SMART Cable repeaters on the seafloor. We’ve developed ultra-low noise omnitilt sensors that operate at any orientation up to 180 degrees, making it the ideal choice for SMART Cable sensor systems where rapid uncontrolled seafloor deployments are required. This technology will transform early tsunami and earthquake detection, global climate monitoring, and critical fiber cable infrastructure resilience, extending our precision sensing capabilities from the lunar surface to Earth’s surface to the deep ocean.
