Agnirva Space Premier League - Expedition #32680: Listening for Health: Monitoring Sound on the ISS to Protect Astronauts

On the International Space Station (ISS), even sound can be a hazard. The experiment titled "A Next Generation Crew Health & Performance Acoustic Monitoring Capability"—developed by SVANTEK and supported by ESA—aims to make space safer by monitoring sound levels in real time.

The ISS is filled with noise from fans, pumps, air conditioners, and scientific equipment. Over time, prolonged exposure to high noise levels can lead to hearing loss, increased stress, and reduced cognitive function among astronauts. This experiment introduces advanced acoustic monitoring systems that can continuously track noise exposure.

The system uses precise microphones and AI-powered analytics to identify sources of noise and measure how sound behaves in the station’s unique environment. Real-time data allows mission control to address any potentially harmful conditions quickly.

In addition to safety, understanding the sound environment improves crew comfort and communication. By designing quieter equipment and optimizing workstation layout, future spacecraft can be engineered with crew well-being in mind.

This technology not only enhances life on the ISS but is vital for future long-duration missions to the Moon and Mars, where maintaining crew health is mission-critical.
