摘要

The most important sound-transmission phenomena in partitions include mass law, coincidence, and mass-spring resonances. Other important effects also exist that significantly affect airborne sound insulation by multi-layer partitions (windows, walls, and floors). This article briefly describes such effects and illustrates them with experimental results. Mass-spring resonances (in triple window glazings) and "linear sound bridge" transmission have been given main consideration.
