I don’t watch any American football but I’ve seen some actual footage (and movie scenes as well). I can only imagine how noisy it gets within the stadium, whether it’s college football or professional football. It will probably be hard to listen to anything else except the crowd’s cheers (and jeers). So what if you needed to hear what your teammates or coaches are saying?

A mechanical engineering professor and a biosystems engineering major at Michigan State have been able to produce something that can help athletes with that problem. Some teams previously just put duct tape inside the earhole of their helmets but they were able to make something better with the power of design thinking and 3D printing” earhole inserts.
These inserts were made from a bio-based plastic called polylactic acid and produced through a 3D printer. They were put into the helmet earholes and the challenge was actually to produce different sizes since different helmets of course had varying sizes. The main purpose is of course to drown out the crowd noise so they can hear play calls and the recently approved coach-to-player helmet communications in the NCAA.
While the around 180 sets they have produced are used by the Spartans, some of the Bowl Subdivision programs are also creating similar tools. For example, the Houston Texans have approached XO Armor Technologies, which can 3D print athletic wearables. After that, around 60 teams have already contacted them to produce sound-deadening earhole covers for their respective teams.
