The document contains acoustic data for different zones in a building including material absorption coefficients and sound level readings taken during peak and non-peak hours. Sound absorption coefficients are provided for various materials used in building components like walls, floors and ceilings. Tables show the peak and non-peak hour sound level readings in decibels at different coordinates within each zone, along with the highest and lowest readings. Furniture materials and their absorption coefficients are also listed.
