2. Project Content

The Qingyuan Radio and Television Station 400㎡ Variety Studio Sound, Light and Electricity System Construction Project centers on the core concepts of "Multi-functionality, Flexibility, and Scenario-based Design," creating a modern studio space integrating stage lighting and mechanical systems, sound systems, large-screen display systems, central control systems, air conditioning and power distribution systems, acoustic systems, motorized seating, and ancillary facilities. 

Core Highlights:

1. Multi-system Integration: Covers 7 major professional systems including lighting, acoustics, sound, mechanics, and central control, achieving intelligent collaborative control of sound, light, electricity, and mechanics to meet diverse program production needs such as variety shows, interviews, and press conferences.

2. Flexible Scene Transformation: The stage performance area design emphasizes dynamic variability. Through the linkage of stage art installations, large-screen content switching, and lighting effects, rapid visual transformation of different scenarios such as interviews, government inquiries, and knowledge competitions can be achieved, enhancing program recognition.

3. Technology Empowering Art: Adopts deep integration of large-screen display systems and lighting matrices, supporting immersive stage art effects combining virtual and real elements; intelligent central control system achieves centralized equipment management, improving production efficiency.

4. Professional Supporting Guarantee: Acoustic system optimizes spatial sound effects, air conditioning and power distribution meet high-load equipment operation, and motorized seating and ancillary room facilities complete the functional layout, ensuring the studio is both professional and user-friendly.

Transmission Frequency Characteristic Curve

Through EASE simulation calculations, the transmission frequency characteristic data for the audience area was obtained. The average sound pressure level from 80-8000Hz is 109.66dB. As shown in the figure above, the transmission frequency characteristic of the audience area can reach: average sound pressure level of 109.66dB from 80-8000Hz, with variation of -4dB~+4dB within this frequency range (1/3 octave measurement). The transmission frequency characteristics of 40-80Hz and 8000-16000Hz are both within the allowable variation range, basically meeting the design requirements.
