Antimicrobial effects of airborne acoustic ultrasound and plasma activated water from cold and thermal plasma systems on biofilms

open access: yesScientific Reports, 2020
Bacterial biofilms are difficult to inactivate due to their high antimicrobial resistance. Therefore, new approaches are required for more effective bacterial biofilm inactivation.

The actual impedance of non-reflecting boundary conditions : implications for the computation of resonators [PDF]

open access: yes, 2004
Non-reflecting boundary conditions are essential elements in the computation of many compressible flows: such simulations are very sensitive to the treatment of acoustic waves at boundaries.

A Comparative Study of Acoustic Regulations for Hospital Bedrooms in Selected Countries in Europe

open access: yesBuildings, 2023
Regulatory acoustic requirements for hospitals exist in several countries in Europe, but many countries have either no or few regulatory limits or only recommendations. The purpose of limit values is to ensure optimal acoustic conditions for the patients

Cannabinoid CB1 receptor agonists do not decrease, but may increase, acoustic trauma-induced tinnitus in rats

open access: yesFrontiers in Neurology, 2015
Tinnitus has been suggested to arise from neuronal hyperactivity in auditory areas of the brain and anti-epileptic drugs are sometimes used to provide relief from tinnitus.

A simple toy model of the advective-acoustic instability. II. Numerical simulations

open access: yes, 2008
The physical processes involved in the advective-acoustic instability are investigated with 2D numerical simulations. Simple toy models, developped in a companion paper, are used to describe the coupling between acoustic and entropy/vorticity waves ...
