Background

Low frequency noise (LFN), defined as noise with a frequency below 100 Hz, is a physical environmental factor generated from many electric devices, including ventilation fans, industrial machines and air-circulating devices. A previous study showed that the exposure of humans to noise at 70 dB did not affect hearing levels in the International Space Station (ISS). However, that previous study monitored noise levels without any consideration of frequency (Hz). Thus, the noise generated from electric devices in the intra-closed area of the ISS may be LFN. In our previous study, constant exposure to LFN for 1 month caused imbalance in mice. In this study, we assess the health risks caused by combined exposure to LFN and microgravity in a closed space, and to develop a non-invasive examination and a method of protection.

Research plan

  1. To assess the health risks co-exposed to LFN and microgravity in a closed space.
  2. To clarify the influence of LFN on the vestibular function.
  3. To assess the comprehensive health risks and to develop a non-invasive examination and a method of protection.
