Silent Playground System Makes Noise Disappear

Advantages of a silent playground system?

• Directional sound technology: Through directional sound technology, the sound is mainly transmitted within the playground, reducing interference with surrounding residential areas. For example, the silent playground system of Qingting Acoustics uses exclusive patented outdoor directional sound technology to concentrate the sound in a fixed area, greatly reducing interference with the surrounding environment
  
• Sound field balance: The system can solve the reverberation and sound asynchrony problems in traditional broadcasting, achieve sound field balance, and improve speech clarity and intelligibility.
  
• Environmental protection and energy saving‌: By reducing noise pollution, it complies with the current environmental protection and energy saving policy requirements, reduces energy waste and operating costs
  

Internet Broadcasting System Solution

The existing campus LAN is used as the transmission medium, and CAT5/CAT6 cables are used to transmit digital audio and control signals. Control and audio commands are sent through the cloud broadcast server, and the directional speakers receive the commands and decode and play them. The system functions are as follows:

• Directional audio (playing in a designated area);
  
• Select and play network audio sources;
  
• Timed playback (break exercises, etc.);
  
• Power timing management (unattended, playback stops);
  
• Networked remote artificial speech;
  

Smart Broadcasting Solution

The intelligent broadcast silent playground control system uses 100V constant voltage signal as audio transmission, and has long-distance audio transmission that is incomparable to ordinary unbalanced analog signals. The system realizes the following functions:

• Directional audio (playback in a designated area)
  
• Multiple sound source selection;
  
• Timed playback (break exercises, etc.);
  
• Power timing management (unattended, playback stops); 
  
• artificial speech amplification;
