DOI: 10.1016/j.jsv.2017.10.002
Abstract: Abstract This paper considers the acoustic performance of a passive damper in which acoustic energy is absorbed by orifices located within a thin plate (i.e. a perforated liner). The perforated liner, which incorporates orifices of… read more here.

DOI: 10.4187/respcare.06269
Abstract: BACKGROUND: Noninvasive ventilation (NIV) is used to treat respiratory failure because it reduces the risks of endotracheal intubation and postextubation respiratory failure. A wide range of different interfaces is available, but concerns exist about rebreathing.… read more here.
