Hosted by the Acoustical Society of China and exclusively sponsored by CRYSOUND , the Final Round of the 3rd “Shenghua Cup”National Acoustic Technology Competition successfully concluded in Hangzhou on October 11, 2025. This year’s competition attracted 61 teams from 39 universities and research institutes across China. Young acoustic talents demonstrated the remarkable strength and creativity of China’s new generation of acoustic researchers through hands-on challenges. The practical testing session of this year's “Shenghua Cup” was designed around real-world acoustic measurement scenarios. Relying on CRYSOUND's self-developed zero-threshold development kit — SonoCam Pi, the competition comprehensively assessed the participants' overall capabilities in system setup, data acquisition, and algorithm implementation. Despite complex testing environments and technical challenges, the participants remained composed and collaborative, skillfully integrating theory with practice and demonstrating solid professional competence. During the academic defense session, expert judges evaluated and questioned the teams from multiple dimensions — including algorithmic logic, technical depth, and application value. The lively exchanges of ideas showcased both the rigorous scientific mindset and the innovative spirit of acoustic research. CRYSOUND also organized the “Exploring the World of Acoustic Technology” tour, opening its showroom and production lines to experts and student teams. Through guided explanations and live demonstrations by CRYSOUND engineers, visitors gained close-up insights into the company’s core products — such as Acoustic Imaging Cameras, SonoCam Pi, Data Acquisition Systems, Measurement Microphones, and Calibrators — and engaged in in-depth discussions on the industrialization pathways of acoustic technologies. As the exclusive sponsor and organizer of the event, CRYSOUND not only provided full hardware and technical support, but also offered participation subsidies to every student team, encouraging them to focus fully on hands-on experimentation in the anechoic chamber without concerns. Jason Cao, CEO of CRYSOUND, remarked: “We hope the ‘Shenghua Cup’ is more than just a competition — it serves as a bridge linking universities, research institutes, and industries. Through this event, many innovative ideas have gained recognition from the industry and even led to potential collaborations. This is the true meaning of ‘industry-academia-research integration.’” While the competition may have concluded, innovation never stops. CRYSOUND extends heartfelt thanks to the Acoustical Society of China, to every expert, teacher, and student for their dedication and passion. Looking ahead, CRYSOUND will continue to work with industry partners to build a more open and dynamic innovation platform, helping more acoustic technologies move from the laboratory to industrial applications — together shaping a brighter future for the field of acoustics.

In sound and vibration testing, flexibility is a decisive factor—especially when test requirements evolve rapidly. SonoDAQ, with its modular, scalable architecture, helps users easily manage everything from simple tests with a single device to complex, large-scale, multi-channel data acquisition. Whether in laboratory environments or industrial sites, SonoDAQ provides efficient, accurate data acquisition solutions, maximizing the adaptability and scalability of the system. Easy Testing with One Device, Scalable Expansion with Multiple Devices When testing requirements are modest, such as road tests or basic vibration testing, SonoDAQ Pro can easily meet the required number of channels with a single device. In this case, users only need one device to perform high-precision data acquisition, which is efficient and helps avoid unnecessary upfront hardware investment. However, as testing needs increase, especially in scenarios that require numerous sensors or synchronized multi-channel acquisition, SonoDAQ offers flexible expansion solutions. Users can connect multiple SonoDAQ Pro units in a daisy-chain or star topology to achieve large-scale data acquisition. For example, when conducting NVH testing or sound and vibration testing for large equipment, users can add more devices as needed, scaling up to hundreds of channels while ensuring high-precision synchronization across all devices. This scalability allows customers to avoid purchasing entirely new acquisition systems each time. By simply cascading existing SonoDAQ Pro units, they can easily cover more complex testing needs and avoid the common issues of device redundancy and high costs seen in traditional systems. Flexible Configuration to Meet Various Needs Even without large-scale acquisition needs, SonoDAQ remains highly flexible. With its modular design, users can easily adjust and reconfigure the system according to changing test requirements. For instance, if only temperature or strain signals are required, users can simply select the corresponding module and insert it into the chassis, without purchasing a new mainframe. This design makes SonoDAQ suitable for everything from simple laboratory tests to complex field tests. Users can expand the system as needed, without worrying about future expansion limits. Whether it's basic data acquisition or advanced signal analysis, SonoDAQ provides accurate, flexible data acquisition solutions, significantly enhancing testing efficiency and cost-effectiveness. Flexibility Brought by Modular Design The modular design of SonoDAQ is the core of its flexibility. Users can select different input modules, output modules, sensor interface modules, and more based on project requirements, and easily plug-and-play or upgrade them as needed. Whether it's adding more sensor channels or expanding with new functional modules, users can quickly implement changes by swapping modules, without affecting the normal operation of the existing system. This design ensures long-term device usability and enables SonoDAQ to adapt to ever-changing test requirements. When future requirements change, such as testing additional signal types (e.g., temperature, pressure, strain), SonoDAQ Pro can easily meet these new testing needs by simply swapping modules, allowing the overall system to continue running efficiently without the need for a full system overhaul. For example, an automotive manufacturer needs to perform NVH testing. Initially, they may only need 4–8 channels for in-car noise testing. In this case, engineers can use a single SonoDAQ Pro device to complete routine testing tasks. When they need to expand the testing scope and add more sensors (such as measuring vibration, strain, or temperature at different locations), they can simply daisy-chain multiple SonoDAQ Pro devices together. Through synchronization technology, they can ensure data consistency across all devices without redesigning the system or changing existing test procedures. Beyond automotive NVH, the same scalable architecture can be applied to aerospace components, industrial machinery, and even high-channel-count consumer electronics testing. Expand as Needed, Effortlessly Tackle Any Testing Challenge The flexible expansion capability of SonoDAQ allows it to scale from simple single-channel testing to large-scale multi-channel data acquisition. Whether it's for in-vehicle testing, industrial monitoring, or scientific research, SonoDAQ provides accurate, reliable data acquisition solutions. Its modular design and flexible system topology not only meet current needs but also enable quick adaptation to evolving testing scenarios in the future. Choosing SonoDAQ means moving away from fixed hardware configurations and instead adjusting the system based on needs, ensuring smooth, repeatable execution of every test. SonoDAQ is ready to transform your testing process—from simple single-device setups to large-scale, multi-channel systems.
