Sub-wavelength phononic crystal liquid sensor [PDF]
, 2011 We introduce an acoustic liquid sensor based on phononic crystals consisting of steel plate with an array of holes filled with liquid. We both theoretically and experimentally demonstrate sensor properties considering the mechanism of the extraordinary ...

The acoustic properties of snores [PDF]
European Respiratory Journal, 1995 This study was undertaken in an attempt to characterize the acoustic properties of snoring sounds in the time and frequency domains, and to correlate between these properties and the mechanical events underlying their production. Three experimental set-ups were used: 1) Dog model--six mongrel dogs, in which partial upper airway obstruction was created ...

Similarities between action potentials and acoustic pulses in a van der Waals fluid [PDF]
, 2018 An action potential is typically described as a purely electrical change that propagates along the membrane of excitable cells. However, recent experiments have demonstrated that non-linear acoustic pulses that propagate along lipid interfaces and ...
