Space Applications
Based on Infrazvuk-M results, recommendations were provided to introduce improved systems, as part of the nominal acoustic noise control system, into the ISS RS modules, for crew protection from the adverse effects of exposure to the interior physical environment, including the acoustic noise in the ISS RS module habitation compartments.

Earth Applications
The Earth Application for this investigation has yet to be identified.

Results/More Information

The measurements showed that the noise generated by the new fan as installed in the SM ventilation system was significantly lower than that of the nominal fan. The reduction in overall noise level, measured at a distance of 50 cm from the fan with the interior panel open, was 2.8 dB.

The noise reduction values as obtained have demonstrated a satisfactory noise-reduction effect through the use of the low-noise fan, which had previously been identified during the ground-based tests.
