Pericardial biomechanical adaptation to low frequency noise stress. Alves-Pereira, M., de Melo, J. J., & Branco, N. A. C. Recent Advances in Multidisciplinary Applied Physics, 2005.

Low frequency noise (LFN) (≤500 Hz, including infrasound) exposure causes thickening of cardiac structures, namely the pericardium - a <0.5 mm thick, 3-layer, translucid sac that surrounds the heart. In LFN-exposed individuals, microscopy studies of their pericardia disclosed the existence of a 5-layered organ, up to 2.33 mm thick. The biomechanical properties which allow this abnormally large organ to coexist with a normal heart function (no diastolic dysfunction is exhibited by these patients) are discussed. The relative positioning of collagen and elastin fibers allow for an unusual reorganization of the extra layers of tissue so that the constant heart expansions and contractions are in no way impeded. The challenges of developing a biotensegrity-based mathematical model describing this new organ is still an open issue.
