Non-sensory Teaching Sound Reinforcement System

Background

One new policy from the Chinese Ministry of Education has been clearly defined the deep integration of information technology and education and teaching, and the use of informatization to improve teachers' informatization teaching capabilities and students' information literacy. It fully realizes full network wired and wireless coverage, and explicitly mentions the use of cloud support and dynamic updates to adapt to hybrid learning, ubiquitous learning and other learning methods. Actively use new technologies such as cloud computing and big data to innovate the construction and application models of resource platforms and management platforms. After the completion of the project, it will definitely help the school improve the quality of education and teaching, cultivate high-quality talents that meet the needs of economic development, and comply with national policies.

System Overview

As a cutting-edge achievement of modern teaching audio systems, the Non-sensory sound reinforcement systemhas brought revolutionary changes to teaching with "non-sensory" as its core highlight.

In traditional sound reinforcement systems, teachers are often subject to many restrictions, while the Non-sensory Sound Reinforcement System allows teachers to completely get rid of physical constraints. Teachers no longer need to wear microphones. Whether they are pacing in front of the podium to explain or writing on the blackboard in front of the blackboard, they can walk and speak, and the sound process is easy and comfortable. This not only greatly reduces the burden on teachers, effectively protects teachers' throats, but also makes the teaching process smoother and more natural.

For students, the sound effects presented by this system are wonderful. The sound output is natural and smooth, and students will hardly notice obvious traces of sound amplification. This feature avoids the problems of excessive volume and sound quality distortion that may be caused by traditional sound reinforcement equipment, creates a comfortable auditory environment for students, and effectively protects students' hearing.

In short, the Non-sensory Sound Reinforcement System is an efficient teaching audio solution that integrates digital innovative technologies, injects new vitality into modern educational and teaching activities, and strongly promotes the improvement of education quality.

Five Advantages

Automatic Feedback Cancelation (AFC): Eliminate howling, ensure sound purity, and improve teaching continuity

Automatic Reverberation Reduction (ARR): Enhance speech intelligibility, avoid sound overlap interference, and create a good acoustic environment

Automatic Gain Control (AGC): Ensures stable volume and makes the teacher's speech clearer and more natural

Automatic Noise Suppression (ANS): Filters ambient noise, reduces noise exposure levels, and protects the hearing of teachers and students

Automatic echo cancellation (AEC): Improve sound clarity and optimize the listening experience of teachers and students

Four Highlights

Natural Sound

Teacher's perspective：Teachers do not need to wear any sound amplification equipment and can move freely, completely free from the constraints of traditional sound amplification. During the teaching process, teachers can speak naturally as usual, and the system can accurately capture the sound and achieve sound amplification, greatly improving the comfort and convenience of teachers' teaching.

Student's perspective：The sound heard from the students is almost the same as the teacher's natural voice. The sound reinforcement effect is natural and smooth, without the obvious electronic sound or distortion of traditional sound reinforcement equipment. It seems as if the teacher is speaking directly at a close distance, creating a high-quality listening environment.

High Sound Quality

Accurate sound reproduction：This technology can highly restore the original timbre, tone and sound quality of the teacher's voice, whether it is a whisper or a loud explanation, it can be restored clearly and accurately, allowing students to receive the most authentic sound information, which helps to improve the quality of knowledge transfer.

Reduce environmental noise interference：Equipped with advanced environmental noise suppression function, it can effectively filter out various background noises inside and outside the classroom, such as fan noise, corridor noise, etc. Even in a complex environment, it can ensure that the teacher's voice is clearly audible and the sound reinforcement is not affected by noise.

Smart Touch Control

Automatic adaptive adjustment:The system has intelligent adaptive capabilities and can automatically adjust the sound reinforcement parameters according to the size of the classroom and the acoustic environment. For example, in classrooms of different sizes and shapes, it can achieve the best sound coverage and sound quality without manual intervention, reducing the threshold for use and maintenance costs.

Smart Touch Control: One-touch switch, free control of microphone volume and feedback volume; convenient operation, adjust exactly as you like.

Protection

Protecting teachers’voice:Since teachers do not need to deliberately increase the volume or use uncomfortable wearable microphones, overuse and damage to the throat are reduced, which helps to maintain the health of teachers' voices in the long term and reduce the risk of throat diseases caused by excessive use of the throat.

Protecting students' hearing: The amplified sound is natural and soft, without any risk of damaging hearing due to excessive volume or sharp sound quality. This ensures students’ hearing health and allows them to study in a comfortable sound environment.
