Silicon Audio Seismic, LLC

Silicon Audio Seismic, LLC, an Austin, Texas-based limited liability partnership and manufacturer, supplies scientific-grade seismic sensors and borehole instruments to federal agencies as a prime contractor (88% of recent awards), competing predominantly under total small business set-asides. The company manufactures geophysical measurement equipment spanning primary NAICS codes in instruments manufacturing (Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables) and related device categories, with a portfolio concentrated in geophysical instrumentation (PSC code).

The vendor's customer base is tightly concentrated among interior and earth-science agencies. The Department of the Interior's US Geological Survey Office of Acquisitions and Grants leads by potential value (6 awards, $15.1 million combined), while the Bureau of Reclamation drives award count (7 awards, $630 thousand combined potential value). NASA's Shared Services Center and the Department of Energy's Office of Science complete the active customer set. This concentration reflects Silicon Audio's core capability: low-noise, high-dynamic-range seismic sensors designed for structural health monitoring, earthquake detection, and planetary science applications. Representative work includes a $38,580 purchase order from USGS in July 2026 for Silicon Audio Low-Noise Optical Seismic Sensors (Model 203-60) with passband 0.005–1500 Hz and ultra-low noise specification (0.5 ng/Hz at 10 Hz), a $119,605 firm fixed price purchase order from the Bureau of Reclamation in August 2023 for seismic recording equipment supporting dam safety monitoring, and a $149,998 Small Business Innovation Research Phase I definitive contract awarded by NASA's Shared Services Center in September 2025 for development of photonic-integrated-circuit (PIC) based physical sensors with low noise and extreme dynamic range.

Activity has remained modest but consistent — one to two awards per year over the past five years — with three awards (combined potential value $189 thousand) completing within the next twenty-four months. Silicon Audio also acts as a sub-recipient on two National Science Foundation–funded grants administered by the University of Arizona: a seismometer development for a lunar network project (June 2024) and a seismometer design for investigating interior asteroid structure (February 2024). The vendor holds a prime federal grant award from the Department of Energy Office of Science for a Digital Monitoring Networks project (awarded July 2025, completion July 2027). Combined potential value across all recent federal sources stands at $15.9 million, with only $1.5 million obligated to date, reflecting the early stages of recent awards.
