摘要

Traditional timber-framed buildings in Southwest China hold international recognition for their historical, cultural, artistic, and social value, yet their physical performance adequacy for modern living remains unexamined. Field tests on Miao dwellings in Jidao Village, Guizhou, characterized wall sound insulation and assessed contemporary suitability. Key results indicate: Newly “L-shaped” dwellings exhibited optimal wall insulation. Critical frequencies in modern walls aligned with experimental ranges, traditional walls showed lower experimental than theoretical values. Traditional exterior wall insulation increased with enclosure (“U-shaped” courtyard > “L-shaped” > “linear layout”, Max≈2 dB), while internal walls showed no significant differences. Enclosed layouts attenuated noise transmission, enhancing overall insulation. Traditional and newly “Linear-type” dwellings showed comparable performance, but new “L-shaped” dwellings with double-layer timber and embedded rock wool (30 mm) outperformed others by 8–14 dB. Exterior and bedroom walls critically influenced overall insulation, directly impacting daily life. Enhancing insulation while preserving ethnic features is essential.
