Living in the
International Space Station is very noisy. It's not like a nightclub, but it's
close, a fascinating place, science fiction and yet, a very noisy place.
Located in orbit around the Earth at an
altitude of about 360 kilometers, a type of low Earth orbit, this place
generates noise ranging between 55 and 78 decibels. That is, the equivalent
volume between a normal conversation or a lawn mower. The noise is generated by
fans that circulate the air in the station. It may seem acceptable, but be
aware that this noise 24 hours a day is heard.
The problem of high noise is such that
the astronauts are forced to sleep with earplugs. This has led to be cases of
decreased hearing ability of astronauts.
NASA continues to work on reducing this
noise. To this end, it has sought to reduce noise with different soundproofing
systems, such as vibration isolation fan, install acoustic panels on the walls
and silencers on vents.
