Although space is a silent place, spaceships are a noisy. The crew members are exposed to harmful levels of noise during space travel. The international space station is constantly buzzing with noise, which affects the crew members. On the International Space Station, air circulation fans and fluid coolant pumps produce a constant level of background white noise, despite sound mufflers and insulation built into the equipment to keep it as quiet as possible. Over time this noise can affect an astronaut’s hearing.
Even during launch the noise resulting from burning of propellant is hazardous. Nike grind materials can be used to shield the inner walls of the spacecraft to make it soundproof. A shield comprising of 2-3 layers of several combination of grind materials can provide significant relief from the noise. Nike grind materials can also be used in space helmets for the same application.
EVA foam having good tolerance for temperatures ranging from -110 degrees to +220 degree centigrade can be used efficiently to manufacture spacesuits.
