Astronaut Samantha Cristoforetti participates in the Acoustic Diagnostics study

iss067e183734 (July 8, 2022) --- Expedition 67 Flight Engineer and ESA (European Space Agency) astronaut Samantha Cristoforetti wears a microphone on her right shoulder for the Acoustic Diagnostics study. The investigation explores whether equipment noise levels and the microgravity environment may create possible adverse effects on astronaut hearing. The acoustic data will help researchers understand the International Space Station’s sound environment and may inform countermeasures to protect crew hearing.
