Whole-home acoustics is not a layer of panels added after the cinema is built. Layout, materials and calibration are designed together so the house is quiet when it should be, and clear when people talk.

About 32 dB background for deep sleep; 300–800 ms reverberation for homes (Tsinghua University Architectural Acoustics Lab & WELL™). Aligned with China’s “Good Housing” agenda, and with private cinema work.

• Bedrooms and living: lower noise, control reverberation
• Open rooms: even sound, so conversation does not vanish
• Private cinema: HAA design and calibration, with a report
• Materials: absorption, diffusion and isolation with the interior
