Partition intersections and their effects on transmission loss and apparent sound transmission class [PDF]
Proceedings of Meetings on Acoustics, 2013 It is widely recognized and accepted that poorly designed intersections between partitions can significantly reduce the sound isolation that is achieved. However, the effect of specific intersection details are not widely reported and available. This presentation will focus on a case study in which different intersection details have been tested in the

Advanced Materials, EarlyView.This study presents a compact dynamic‐field‐driven nucleation and growth (DFNG) model that captures ferroelectric switching behavior under arbitrary voltage waveforms. It enables extraction of time‐dependent domain wall velocity and growth dimensionality, which can then be extended to device‐level modeling.
