In these sleeping quarters, the only audible noise generated by the station comes from the fans providing airflow for comfortable sleeping conditions. To do this, the sleeping enclosures are located at the edges of the station and are fitted with doors that can close them off from the surrounding area. To avoid sleep disturbances, these sleeping pods aim to achieve sound levels of 50 dBA or quieter. When it comes time to wind down from a busy day, crew members have designated sleeping pods where they can have a brief respite from the station’s ever present noise. These continuous noise sources are major factors in the crew members’ daily noise exposure, just like they are when used for HVAC in office buildings, residences, and labs here on Earth. “…now I can’t remember what it is like to be in silence.” Upon leaving the station, Kelly reminisced about his sonic experience: This stood true for 520 days, nearly a year and a half, during Kelly’s stay aboard the ISS. “…our lives without fan noise were over…” US astronaut Scott Kelly remarked in his Book Endurance that upon first arriving at the ISS, It takes a lot of fans and compressors running continuously to maintain stable conditions for humans. The atmosphere is designed to mimic earth’s atmosphere, where sound propagates through air from a source to a receiver. Other, more constant noise sources come from equipment required to keep the artificial atmosphere aboard the ISS human friendly. Environmental, Industrial, & Transportation.
