With the rise of online education and hybrid teaching, classrooms need clearer voice acquisition and sound reinforcement systems to support recording, live broadcasting and remote interaction. The traditional sound reinforcement system is insufficient, and the non-sensing sound reinforcement system is created to solve these problems. Natural Teaching Reinforcement (NTR) is a classroom audio technology based on natural acoustic enhancement, which aims to optimize the clarity and comfort of teachers' teaching voices while reducing the interference of electronic sound reinforcement.
Core algorithm of non-sensing sound reinforcement
- Automatic Feedback Suppression (AFC): Eliminate howling, ensure sound purity, and improve teaching continuity
- Automatic Noise Suppression (ANS): Filter environmental noise, reduce noise exposure, and protect the hearing of teachers and students
- Automatic Echo Cancellation (AEC): Improve sound clarity and optimize the auditory experience of teachers and students
- Automatic Reverberation Reduction (ARR): Enhance language intelligibility, avoid sound overlap interference, and create a good acoustic environment
- Automatic Gain Control (AGC): Ensure stable volume, making the teacher's language clearer and more natural
Advantages of non-sensing sound reinforcement system
- Free teachers from speaking constraints and protect their throats. Teachers do not need to wear or hold microphones when giving lectures, and do not need to deliberately give lectures loudly;
- Good sound reinforcement listening experience. The sound heard by students is almost the same as the teacher's natural voice, and the sound reinforcement effect is natural and smooth;
- Accurate sound restoration, highly restore the original timbre, tone and sound quality of the teacher's voice, which helps to improve the quality of knowledge transfer;
- Reduce environmental noise interference, environmental noise suppression function, can effectively filter out various background noises inside and outside the classroom;
- Automatic adaptive adjustment, adaptively adjust the sound effect according to the on-site sound reinforcement environment
- Simple and convenient operation, one-button switch, free control of microphone volume and feedback volume; convenient operation, precise adjustment...
