Trends in the acoustic environment at the International space station in the period of time of the ISS missions from one to fifteen

: Acoustics measurements in the Service module of the International space station were performed at the workplaces with the vehicle and life support systems and equipment in operational status, and at the crew sleeping sites. Analysis of the measuring results revealed violation of the noise limits across the whole module. Measures were taken to abate noise at the place of origin and along the propagation path in order to prevent its negative effects on crew health.
