The SV-SSL128\/64<\/strong> is a high-density MEMS microphone array system<\/strong> developed for real-time passive acoustic sensing and sound source localization.<\/p>\n The system integrates 128 or 64 synchronized MEMS microphones into a compact array with an approximately 450 mm aperture<\/strong>. By analyzing the time differences between acoustic signals received by different microphones, the system can estimate the direction and position of multiple sound sources.<\/p>\n Core processing is based on Time Difference of Arrival (TDOA)<\/strong> and beamforming<\/strong>, enabling the system to convert acoustic signals into spatial information.<\/p>\n The result is more than a conventional microphone array. The SV-SSL128\/64 provides a complete acoustic sensing foundation for applications requiring sound detection, localization, directional pickup, tracking and AI-based acoustic recognition<\/strong>.<\/p>\n One of the key characteristics of the SV-SSL128\/64 is its passive acoustic sensing architecture<\/strong>.<\/p>\n The system does not need to transmit RF, ultrasonic or other active detection signals. Instead, it continuously receives and analyzes naturally generated acoustic signals from the surrounding environment.<\/p>\n This passive operating principle provides several advantages:<\/p>\n The system can therefore serve as an acoustic sensing layer alongside other technologies such as cameras, radar and AI perception systems.<\/p>\n The SV-SSL platform is available in two channel configurations:<\/p>\n The 128-channel configuration provides a high-density spatial sampling architecture for applications requiring higher spatial resolution and advanced multi-source acoustic analysis.<\/p>\n It is particularly suitable for:<\/p>\n The 64-channel configuration provides a balance between spatial resolution, system complexity, power consumption and deployment cost.<\/p>\n It is suitable for:<\/p>\n Both configurations use synchronized MEMS microphone acquisition to provide a consistent multi-channel acoustic data foundation.<\/p>\n The SV-SSL128\/64 uses Time Difference of Arrival (TDOA)<\/strong> technology to estimate the direction of incoming acoustic signals.<\/p>\n When a sound source generates an acoustic wave, the wave reaches each microphone at a slightly different time depending on the source position and propagation path.<\/p>\n By comparing the relative arrival time between microphone channels, the system can calculate the acoustic source direction.<\/p>\n The localization pipeline can be represented as:<\/p>\n Synchronized MEMS Acquisition \u2192 TDOA Estimation \u2192 Beamforming \u2192 Spatial Localization \u2192 Multi-Source Tracking \u2192 AI Recognition<\/strong><\/p>\n This architecture enables the platform to transform raw acoustic information into actionable spatial data.<\/p>\n In addition to TDOA localization, beamforming technology can be used to spatially focus on specific directions.<\/p>\n This enables the system to:<\/p>\n The system can output multiple directional audio channels<\/strong>, allowing external software or AI algorithms to further process and classify individual sound sources.<\/p>\n A single SV-SSL array provides broad spatial acoustic coverage:<\/p>\n Actual detection distance depends on the acoustic output of the target, background noise, atmospheric conditions, installation environment and target-to-array geometry.<\/p>\n For larger monitoring areas, multiple arrays can be deployed as a distributed acoustic sensing network<\/strong>.<\/p>\n Multiple SV-SSL arrays can work together to extend the monitored area and improve spatial awareness.<\/p>\n A distributed deployment can combine localization information from multiple acoustic nodes to support:<\/p>\n This architecture allows system integrators to build scalable acoustic sensing networks rather than relying on a single sensing node.<\/p>\n Localization provides information about where a sound is coming from<\/strong>. AI acoustic recognition can provide additional information about what type of sound is being detected<\/strong>.<\/p>\n The SV-SSL128\/64 can therefore be integrated with AI models for sound classification and event recognition.<\/p>\n Potential AI processing functions include:<\/p>\n This creates a complete processing chain:<\/p>\n Detect \u2192 Localize \u2192 Track \u2192 Recognize \u2192 Classify \u2192 Verify<\/strong><\/p>\n AI processing can be implemented on an external edge-computing platform or integrated into a larger sensor-fusion architecture.<\/p>\n The system consumes approximately 4 W<\/strong>, making it suitable for applications where power availability is limited.<\/p>\n The low-power architecture supports:<\/p>\n For remote locations, the SV-SSL128\/64 can be combined with solar power, battery storage and wireless or wired networking to create autonomous acoustic monitoring nodes.<\/p>\n With up to 16 simultaneous target sources<\/strong> and a sound imaging frame rate of up to 25 FPS<\/strong>, the system can provide real-time spatial information about multiple acoustic events.<\/p>\n This makes the platform suitable for environments where several sound sources may exist simultaneously.<\/p>\n The system can output:<\/p>\n These outputs can then be displayed through a PC application, edge-computing system or customized visualization platform.<\/p>\n The same technology used for sound source localization can also be applied to industrial acoustic diagnostics.<\/p>\n Machines and industrial equipment generate characteristic acoustic signatures during normal operation.<\/p>\n Changes in these signatures can indicate abnormal operating conditions such as:<\/p>\n The SV-SSL128\/64 can provide both spatial information and directional audio<\/strong>, helping maintenance systems identify not only that an abnormal acoustic event occurred, but also where it originated.<\/p>\n Continuous passive acoustic monitoring can provide an additional sensing layer for large sites and protected areas.<\/p>\n The system can detect, localize and classify acoustic events and provide directional information to a central monitoring platform.<\/p>\n The platform can be deployed around large facilities and infrastructure to provide continuous acoustic awareness and detect abnormal acoustic events.<\/p>\n Large public or private events can use distributed acoustic sensing nodes to monitor acoustic events across multiple areas.<\/p>\n Factories, production lines and industrial facilities can use acoustic localization to identify abnormal equipment sounds and determine their physical location.<\/p>\n The system can also be used for long-term monitoring and spatial analysis of environmental sound sources.<\/p>\n With high-density MEMS microphone channels and spatial acoustic information, the platform provides a hardware foundation for developing customized AI acoustic perception systems.<\/p>\n Actual performance depends on target acoustic characteristics, environmental noise, installation geometry, atmospheric conditions and system configuration.<\/em><\/p>\n Up to 128 synchronized MEMS microphones provide a high-density spatial sampling platform for advanced acoustic localization and beamforming.<\/p>\n The system listens to naturally generated acoustic signals without transmitting active detection signals.<\/p>\n TDOA-based processing provides rapid directional localization with a typical localization time of approximately 100 ms.<\/p>\n The system provides both azimuth and elevation information, enabling three-dimensional acoustic localization.<\/p>\n The system can process and track multiple acoustic sources, supporting up to 16 simultaneous targets under suitable conditions.<\/p>\n Approximately 4 W power consumption enables remote, distributed and solar-powered deployments.<\/p>\n The acoustic localization layer can be combined with AI sound recognition and classification to create an intelligent acoustic perception system.<\/p>\n Multiple arrays can be combined to create a distributed acoustic sensing network covering larger areas.<\/p>\n The SV-SSL128\/64 is designed not simply as a microphone array, but as an acoustic perception platform<\/strong>.<\/p>\n By combining high-density MEMS microphones, synchronized acquisition, TDOA localization, beamforming, directional audio and AI-based sound recognition, the platform provides the core sensing layer required for next-generation intelligent acoustic systems.<\/p>\n For system integrators, researchers and OEM\/ODM customers, SISTC can further support customized microphone configurations, array geometry, acoustic algorithms, edge computing integration and multi-sensor system development.<\/p>\n SISTC \u2014 MEMS Microphone Technology and Intelligent Acoustic Sensing Solutions<\/strong><\/p>\n Want to see how the SV-SSL128\/64 renders real-time acoustic beamforming maps?<\/p>\n
