About Silicon Audio
Silicon Audio is a company that received a SBIR Phase I grant for a project entitled: High Performance Directional MEMS Microphones for Communication Devices. Their project will investigate a novel MEMS based microphone based on entirely new design principles. By abandoning the traditional 100 year-old microphone architecture common to both full-scale microphones as well as recently commercialized MEMS microphones, this project will explore a vastly superior acoustical design that will result in substantial improvements in fidelity and SNR (20 dB SNR improvement over existing MEMS microphones). Furthermore, the microphone will have an inherently directional response with the benefit of focusing on a speaker or event of interest while rejecting ambient background noise. These attributes make this innovation ideal for addressing an emerging need of high volume consumer communication device manufactures that are looking for acoustic sensing innovations with the unique combination of high performance and low manufacturing cost. If successful the proposed innovation will enable, for the first time, the introduction of performance-audio quality into a suite of consumer communication devices. The primary customer focus for this innovation is high volume consumer communication device manufacturers with applications on their horizon that demand substantial improvements in microphone component performance. Presently, commercial suppliers of MEMS microphones all use variations of a traditional microphone architecture which has proven incapable of addressing high performance applications, in particular those that require high fidelity and directionality. Additional markets and applications for this innovation include acoustic instrumentation, performance audio, military and defense, intelligence gathering, speech recognition (ex. in laptop computers), and hearing aids. Addressing hearing aid markets will have a societal impact as well, as patient satisfaction with hearing aid devices is presently very low. The innovation is also expected to have other audiological applications including use in hearing health monitoring systems based on otoacoustic principles. Clinical tools and instruments based on this innovation will serve to enhance scientific and technological understanding in many fields of acoustics.

Silicon Audio Brings Optics Technology to Traditional Land, Marine, and Scientific Seismic Sensors October 27, 2014 -- DENVER, Oct. 27, 2014 /PRNewswire/ --SEG 2014 Silicon Audio , a technology innovation company, today announced its low-noise optical seismometer at the 2014 SEG International Exposition in Denver, booth #2188. The new seismic sensor is the same size and shape as a conventional geophone, but it uses optics technology to record much lower frequencies at a previously unachievable noise floor. The new measurements enabled by Silicon Audio's low-noise optical seismometer will help to close the gap between exploring for oil and definitively finding it. "At Silicon Audio, we've engineered a new way to detect seismic data. By combining the reliable mechanics of the conventional geophone with optics technology, our new seismometer captures more data with greater sensitivity than has been previously possible using a single geophone or scientific instrument," said Coe Schlicher, CEO of Silicon Audio. "In an industry where exploration is increasingly challenging and requires greater adaptability in tougher terrain, our optical seismometer offers scientific-grade performance and wide dynamic range in a rugged, easy-to-deploy form factor. We're now looking for forward-thinking companies to partner with us and leverage our sensor's advantages in the market. " The low-noise optical seismometer uses a laser to read the motion of a vibrating proof mass, achieving a high signal-to-noise (SNR) ratio and recording lower frequencies compared to existing geophone technology. It has versatile broadband response capabilities and delivers high-quality data at both large- and small-signal levels simultaneously. The rugged, reliable seismometer integrates seamlessly into existing geophone architectures without any special handling. Marine, Land, and Scientific Use The Silicon Audio optical seismometer combines the rugged and reliable form factor of traditional geophones and powerful measurement capabilities of scientific instruments, offering a single seismometer that can take scientific-grade measurements and be deployed in places that previously required multiple units. With the optical seismometer, engineers in marine applications can detect low-frequency (sub 1Hz) signals with high fidelity, translating to an additional decade of low-frequency data for deeper imaging into the seafloor. The same technology offers a flat response from 0.1 Hz to 1 kHz, low cross-axis sensitivity, and low power making it ideal for land-based seismic exploration across difficult terrain. In other applications, researchers get scientific-grade broadband performance with higher clip levels. All the while, the rugged structure, familiar form factor, and reliability of the optical seismometer make it easy to use and quickly take advantage of new, robust measurement capabilities. Features and Benefits Low-Noise Measurement: Achieves below 5 ng/ Hz from 1.0 Hz to 400 Hz, surpassing that of MEMS and conventional geophones and well suited for passive seismic applications. High Clip Level: With a clip level of +1.5 g pk, dynamic range exceeds that of state-of-the-art analog-to-digital converters, enabling system integrators to make full use of the data. Omnidirectional: Silicon Audio's sensor is tilt insensitive and operates in any orientation, enabling rapid deployment without the hassle and additional operating expense of leveling. Low Frequency: The ability to capture low-frequency (sub 1 Hz) signals with high fidelity translates to an additional decade of low frequency data for deeper imaging. Form Factor: Small size, low power, and ultra portability make the sensor ideal for high-density array applications and field installations. Reliable Design: The optical seismometer is shock tested to 3000 g to withstand the rigors of seismic deployment, and is customizable to fit within existing acquisition systems. Flexible Configuration: Offered in single-axis or three-axis configurations, and a small, single-element diameter (1.25") positions it for applications such as borehole deployment. Extensively Tested Performance down to 0.1 Hz has been verified in tests performed at the Albuquerque Seismology Laboratory, part of the United States Geological Survey. The Silicon Audio optical seismometer has been used to record distant seismic events originating thousands of miles away, as well as the earth's natural background noise including the 5-second period microseism. Upcoming Opportunity Silicon Audio is now looking for companies that will use this low-noise optical seismometer technology to close the gap between exploring for oil and definitively finding it.
