Astronauts and the challenges of speaking in space
太空人與在太空中說話的挑戰
Have you ever wondered what it is like to speak in space?
你曾經好奇過在太空中說話是什麼感覺嗎？
Many people assume there is no sound at all because space is a vacuum, but the reality is more nuanced.
許多人假設太空裡完全沒有聲音，因為太空是真空狀態，但事實上要複雜得多。
While sound cannot travel through the emptiness of outer space, astronauts communicate easily inside the pressurized environment of the International Space Station.
雖然聲音無法透過外太空的虛無傳播，但太空人在國際太空站的加壓環境中卻能輕鬆交流。
However, things get complicated during an Extravehicular Activity, or a space walk.
然而，在進行艙外活動(E-V-A)，即所謂的太空漫步時，情況就變得棘手。
Inside a spacesuit, life-support fans and pumps create constant, deafening noise.
在太空服內，維持生命的風扇與幫浦會造成持續且震耳欲聾的噪音。
To ensure clear communication, engineers use specialized microphones placed close to the astronaut's mouth to filter out mechanical drones.
為了確保通訊清晰，工程師使用放在太空人嘴邊的專用麥克風來過濾機械的嗡嗡聲。
Microgravity causes fluids to shift toward the head, often leading to nasal congestion that can subtly alter the sound of an astronaut's voice.
微重力會導致體液向頭部移動，這常導致鼻塞，進而細微地改變太空人的聲音。
Because radio signals between space and Earth can be distorted by distance and interference, crews rely on 'International Space Station English,' a simplified, disciplined version of the language.
因為太空與地球之間的無線電訊號可能會因距離與干擾而失真，機組人員倚賴著「國際太空站英語」，這是一種簡化且訓練有素的語言版本。
