School teaching audio teacher amplification equipment

　　Product Introduction

Balanced Sound Field System for Clear Listening Acoustics Classroom（School teaching audio teacher amplification equipment）Introducing the concept of balanced sound field in the construction of classroom sound environment, the system solves the problems of mutual interference, reverberation, delay, etc. between existing classroom broadcasting rooms through professional sound field simulation design, achieving uniform sound propagation in the student listening area, ensuring that students in the front and back rows of the classroom can hear the teaching content clearly, and achieving the goal of educational equity; The intelligent and humanized design of "one teacher, one microphone" creates a unique "educational business card" for each teacher, and creates high-quality and healthy ear protection classrooms.

　　Classroom Balanced Sound Field System

　　Creating a high-quality classroom with balanced sound field and healthy ear protection

The classroom is an important place for teenagers to receive education and teaching. The overall sound environment of the classroom directly affects the quality of teaching and is closely related to students' listening health. The listening condition of teenagers affects their learning, communication, physical and mental health, and is more related to national education and future competitiveness. Therefore, improving the classroom sound environment and strengthening the protection of hearing health for teenagers and children are crucial.

The concept of balanced sound field is introduced in the construction of classroom sound environment, through professional spatial sound field design, integration of independent algorithms and audio technology, to achieve balanced propagation of lecture sound in the student listening area, achieving a sound pressure level difference of less than 2dB at different positions, ensuring the sound quality of students in the front and back rows, effectively protecting students' hearing health, and achieving the goal of educational equity.

Compared to traditional amplification devices in the past, clear listening acousticsClassroom Balanced Sound Field System（School teaching audio teacher amplification equipment）Greatly improved the problem of teachers using their voices under high load. The teacher only needs to speak at a normal volume, and the students in the back row can also hear clearly. Using innovative acoustic equipment to assist teaching not only improves the teaching environment, but also enhances children's absorption rate of knowledge and improves classroom sound quality.

　　Composition of classroom balanced sound field system

Clear Listening AcousticsClassroom Balanced Sound Field SystemIt consists of two parts: a teaching grade professional speaker and a wireless microphone.

　　1Teaching grade professional speaker

The device adopts an integrated and minimalist design, integrating wireless microphone, Bluetooth, and professional DSP amplifier into one, plug and play; Usually, a special angle installation method is used on one side of the blackboard to effectively reduce reverberation interference caused by sound wave reflection and achieve concentrated and balanced propagation of the sound field in the student listening area.

① High specification acoustic configuration: balanced sound propagation, clear and natural

② Integrated minimalist design: easy installation, convenient application

③ Multi functional driver: supports AUX-IN, wireless MIC, Bluetooth connection

　　2. Wireless microphone

By utilizing high-performance steering control speech algorithms, we aim to achieve excellent levels of classroom speech clarity (STI), allowing teachers to deliver clear and bright lectures at normal volumes while effectively protecting their voices.

① One teacher, one microphone: easy teaching, instant use

② Teaching without cross frequency: high fidelity sound quality, no whistling

③ Large capacity battery: can be used continuously for more than 4 hours

　　Core strengths

　　Create a balanced sound field

By using unique acoustic algorithms and audio processing techniques, the amplitude of sound on the ceiling and floor is reduced, achieving balanced propagation of sound in the classroom listening area and achieving a sound pressure level difference of ± 2dB between the front and rear rows.

　　AlI IN-ONE design

Integrated design, integrating wireless, Bluetooth, amplifier and other functions, with intelligent and humanized configuration of one teacher and one microphone, creating a unique "educational business card" for each teacher.

　　Protecting hearing health

A balanced listening experience protects students' ear health, with soft and clear teaching sounds that are smooth and balanced, providing high ear comfort. This can effectively protect students' hearing and alleviate the burden on teachers' vocal cords.

　　Prevent cross frequency teaching

Each classroom has one frequency point, and the equipment can successfully match frequencies within a range of 1M. Adjacent classrooms do not interfere with each other, preventing the occurrence of cross frequency and improving teaching order and environment.

　　Promote and apply in multiple locations and schools

In 2023, the Institute of Acoustics of the Chinese Academy of Sciences and the Institute of Acoustics of the Chinese Academy of Sciences jointly set up the "Acoustics Innovation Joint Laboratory" and the "Hearing Protection Research Center". The two sides jointly launched the "Ten Thousand Schools for Clean Listening" campaign, enlisted wan schools nationwide, piloted the deployment of a classroom balanced sound field system, integrated more comprehensive classroom acoustic environment status and common problems, and further optimized the classroom acoustic environment design scheme.

On the road of empowering hearing health with technology, Clear Listening Acoustics has invested consistent ingenuity and efforts, using technological power to assist in safeguarding students' hearing health protection projects, continuously promoting innovation and application of acoustic technology achievements, establishing industry standards and benchmarks, and providing users with smarter, more personalized, and healthier listening experiences.

　　Regarding Clear Listening

Qingting Acoustics was founded in 2015, focusing on the research and application of innovative acoustic technologies. We are committed to integrating innovative acoustic technologies with industry needs and expanding the implementation of "sound+" innovative application solutions in various industries. Since 2020, Qingting Acoustics has continued to pay attention to the protection of adolescent hearing health. By utilizing its own acoustic advantages, we have successively launched campus smart sound and hearing protection projects jointly built by schools and enterprises.

As a leading enterprise in domestic acoustic innovation, Qingting Acoustics has always been based on the strategic focus of acoustic innovation, adhering to technological innovation as the core driving force, relying on innovative acoustic technologies such as directional sound generation, sound source positioning, sound imaging, sound detection, and balanced sound field control, to develop products and services based on various acoustic technologies, creating a full scene intelligent innovation "sound state chain", and continuously empowering industry innovation with technological innovation.
