Sound Insulation Evaluation of High-Performance Wood-Frame Party Partitions under Laboratory and Field Conditions.

摘要

Several building codes require airborne and impact sound insulation of Sound Transmission Class (STC) and Impact Insulation Class (IIC) greater than or equal to 50, 5 points higher than minimum property standards. This report describes lab and field data for wood-frame party walls and floors well in excess of the higher requirements. To explain and justify the high transmission loss (TL) performance, a combination of recent improvements in approximate TL theory and lab-field technologies is used. This combination proves a powerful tool in providing new insights into previous and current data. An abbreviated summary of these technologies is provided in the appendix.
