Doctor of Directional Listening is a pioneer in intelligent directional sound guidance, a leading enterprise in acoustic innovation R&D, and a national high-tech specialized "Little Giant" enterprise. In collaboration with Tsinghua University's Acoustics Lab, deep partnerships with Nanyang Technological University Singapore, and the establishment of the first scientific technology innovation lab with Brunei Polytechnic, Doctor of Directional Listening is committed to commercializing directional sound technology and integrating ultrasonic carrier technology with artificial intelligence.

Adhering to technological innovation as its core, Doctor of Directional Listening has developed the Silent Playground Series, Smart Square Dancing Series, Exhibition Directional Audio Series, and Bank Bidirectional Directional Audio Series...

Doctor of Directional Listening provides end-to-end solutions, from directional acoustic environment design and customized directional speaker products to directional sound source processing and central control system R&D. The company strives to enable people to "control sound like controlling light beams," fundamentally improving acoustic environment quality and enhancing auditory experiences.

As the world's first truly civilian-oriented directional acoustic environment system, the company's products can be widely applied in bank branches, various service halls, public transportation, airport terminals, high-speed rail and light rail systems, exhibitions, outdoor advertising, schools, hospitals, supermarkets, convenience stores, smart buildings, and public entertainment facilities. With growing public awareness of personal privacy protection and noise interference prevention, the technology will also expand into automotive, mobile devices, and other key technology sectors, gradually extending into personal consumer applications.

Hardware Barriers:
Encrypted hardware architecture, a finely-tuned confidential supply chain system, and plans for future independent micro-controller unit (MCU) development. Continuously iterating material technology advancements rank among the world's foremost.

Algorithm Barriers:
Seamless integration of proprietary algorithms with hardware; high robustness validated through engineering applications; proven control effectiveness recognized by clients; high algorithm efficiency with minimal hardware resource consumption, verified across multiple IC platforms.

Parameter Barriers:
Hardware-software coordination relies on extensive empirical parameters accumulated over long-term development, making product replication through hardware imitation alone impossible. Unique parametric model designs significantly enhance R&D efficiency.

Intellectual Property Barriers:
New patent applications filed quarterly, with a comprehensive internal IP portfolio already established.
