Educational Audio System Solutions

Background

Education is a matter of great importance for the future, and it is related to the development of several generations. With the increase of national investment in education in recent years, the era of intelligent and informationalized educational equipment has arrived, and the informationalization of education is also ushering in a new stage led by 'wisdom'.
The 13th Five-Year Plan for Education Informatization clearly states that we should continue to promote the "One Excellent Lesson for One Teacher, One Teacher for One Lesson" activity, encourage teachers to use information technology to innovate teaching models, and promote the formation of a new normal of information-based teaching that is "used in the classroom, used frequently, and used universally".
At present, the systems applied in the education industry mainly include local sound reinforcement systems, normal recording and broadcasting systems, interactive recording and broadcasting systems, etc;
The Tongchuang Audio digital audio processor provides perfect processing capabilities for the above systems with newly upgraded algorithms for de-harshing, de-echoing, and noise reduction for the education industry;

Solution

This system can achieve local sound reinforcement while also enabling real-time communication with other institutions. The implementation of these functions requires the use of AFC/AGC/ANS/AEC algorithms to solve problems such as acoustic feedback, noise reduction, and echo cancellation through the 5A algorithm, achieving measurable educational speech.
Strong howling suppression capability: Creat Audio's newly upgraded adaptive feedback suppression algorithm is perfectly suited for classroom sound reinforcement systems, solving the problems of howling and low gain caused by ultralong-distance pickup of overhead microphones, ensuring clear and loud teacher lectures;
Perfect echo cancellation: Strong echo cancellation ability, with a processing tail length of up to 512ms, completely solving the echo problem in interactive teaching processes;
Noise suppression capability: noise cancellation up to 23db, ensuring clear recorded video and voice, solving annoying noise problems;
