Mott Making Life in Space More Comfortable

Mott’s Porous Cup Suppresses Excessive Gas Flow Noise


When astronauts leave to explore space, they have to have living chambers that regularly provide them with oxygen. This is achieved through a steady flow of oxygen to their chambers.


When flowing gases inside such small spaces, it can get quite loud. Astronauts stay in space for months, if not years at a time and are confined to these small chambers, so there is no way to escape from the noise.

Mott provided a porous cup to aid in suppressing the noise. The porosity of the cup acted as a natural muffler when gas was passed through it, therefore reducing the noise decibel level to make it more bearable for the long-time inhabitants.
