About Us

Headquartered in the National Science City in Huairou District, Beijing, Beijing GroupCore Acoustic Technology Co., Ltd. is an innovative technology enterprise dedicated to the research, development, and industrial application of intelligent acoustic sensing technology.

The company’s core R&D team originates from an international senior acoustic laboratory. After a decade of localized technological accumulation, it has formed a complete acoustic core technology system. Drawing on the advanced technological resources of Beijing Information Science & Technology University, Tsinghua University, Peking University, and well-known domestic acoustic laboratories, the company has built an R&D closed loop for acoustic, optical, and electrical multimodal sensing fusion. It possesses full-chain R&D capability spanning sensor hardware design, data acquisition and signal processing, algorithm development and model training, system integration and scenario validation, and feedback-driven iterative optimization.

Core Technology: Holographic Sound Field Inspection

Holographic sound field inspection is the company’s core technology direction, having built complete technical capability from “macroscopic panoramic perception” to “microscopic holographic insight.”

At the macroscopic level, the holographic sound field inspection instrument adopts a spherical microphone array design and can achieve one-shot panoramic sound field acquisition of hemispherical space (360°×180°), thoroughly eliminating the inspection blind zones caused by a limited field of view in conventional equipment. The system carries a proprietary AI multi-source blind source separation algorithm and offers 12 dB equivalent noise reduction capability, precisely locking onto the target source position even under strong background noise and high reverberation.

At the microscopic level, the NAH2048 large-array near-field acoustic holography system employs a 2048-channel high-density microphone array. Based on Near-field Acoustic Holography (NAH) technology, it breaks through the physical diffraction limit, raising the localization accuracy of low-frequency sources from “meter-level blur” to “centimeter-level precise localization,” and can precisely identify core problems such as bearing faults and abnormal-noise excitation points.

Solution Portfolio

The company provides full-stack acoustic solutions covering multiple scenarios and industries:

R&D Capability

The company has built a complete acoustic AI R&D technology stack:

• Acoustic database: possessing more than 23 million acoustic data entries, covering multiple operating conditions and application scenarios, providing a solid foundation for algorithm training and model iteration.

• Algorithm toolbox: the proprietary signal processing algorithm toolbox QHAgent integrates nearly 300 advanced algorithms and can process multiple signal types including vibration, rotational speed, displacement, and acoustics; the equipment intelligent maintenance algorithm toolbox GroupcoreAgent and the battery intelligent maintenance algorithm toolbox BatteryAgent provide dedicated algorithm support for industrial equipment and energy storage systems, respectively.

• Acoustic model training capability: possesses end-to-end acoustic model training capability spanning data acquisition, cleaning, annotation, feature extraction, model training, and iterative optimization, enabling rapid deployment of high-precision customized models for specific scenarios such as industrial fault diagnosis, abnormal-sound recognition, and equipment predictive maintenance.

• Large model and multi-agent technology: based on a large language model and multi-agent architecture, it achieves conversational dynamic composition and automatic generation of intelligent maintenance algorithms, significantly lowering the threshold for algorithm application.

The company is a member unit of the China Sensors and IoT Industry Alliance, a member unit of the Intelligent Inspection Equipment Industry Development Alliance, and a member unit of the DAMA International Data and AI Management Association.
