Khodorkovsky Russia's central air-Ru Fluid Dynamics Institute researchers say they have developed and tested two low-noise space station ventilation equipment to ease the International Space Station, the problem of excessive noise.

         The researchers said that the ventilation equipment to meet the requirements of the various aerodynamic parameters at the same time, the noise reduction from 5.5 to 8 db. This is a major breakthrough, because many experts believe that, in this regard will reduce noise from 1.5 to 2 db it is very easy.

         According to the Russian Space Agency introduced the application of the device will greatly improve the working conditions of the international space station, in addition to low noise, but the device can also have a strong pressure to ensure that the station forced air convection heat transfer.

         According to reports, the International Space Station space experts to make the noise problem has been a headache, they believe that the station would be detrimental to excessive noise astronaut health. Currently the International Space Station to take a set of protective measures, such as the use of Russian life-support system developed for insulation materials, ventilation below the space station also installed a special shock absorbers to help reduce noise. Astronauts sleep or too much noise when working near some equipment, but also on noise canceling filter silencers or wear special earplugs.
