Michigan State engineering prof, student design helmet inserts to help drown out crowd noise for QBs


EAST LANSING, Mich. — The sight was a common one for Andrew Kolpacki. For many a Sunday, he would watch NFL games on TV and see quarterbacks putting their hands on their helmets, desperately trying to hear the play call from the sideline or booth as tens of thousands of fans screamed at the tops of their lungs.

When the NCAA’s playing rules oversight committee this past spring approved the use of coach-to-player helmet communications in games for the 2024 season, Kolpacki, Michigan State’s head football equipment manager, knew the Spartans’ QBs and linebackers were going to have a problem.

“There had to be some sort of solution,” he said.

As it turns out, there was. And it was right across the street.

Kolpacki reached out to Tamara Reid Bush, a mechanical engineering professor who not only heads the school’s Biomechanical Design Research Laboratory but also is a football season ticket-holder.

Kolpacki “showed me some photos and said that other teams had just put duct tape inside the (earhole), and he asked me, ‘Do you think we can do anything better than duct tape,?” Bush said. “And I said, ‘Oh, absolutely.’”

Bush and Rylie DuBois, a sophomore biosystems engineering major and undergraduate research assistant at the lab, set out to produce earhole inserts made from polylactic acid, a bio-based plastic, using a 3D printer. Part of the challenge was accounting for the earhole sizes and shapes that vary depending on helmet style.

Once the season got underway with a Friday night home game against Florida Atlantic on Aug. 30, the helmets of starting quarterback Aidan Chiles and linebacker Jordan Turner were outfitted with the inserts, which helped mitigate crowd noise.

DuBois attended the game, sitting in the student section.

“I felt such a strong sense of accomplishment and pride,” DuBois said. “And I told all my friends around me about how I designed what they were wearing on the field.”

All told, Bush and DuBois have produced around 180 sets of the inserts, a number that grew in part due to the variety of helmet designs and colors that are available to be worn by Spartan players any given Saturday. Plus, the engineering folks have been fine-tuning their design throughout the season.

Dozens of Bowl Subdivision programs are doing something similar. In many cases, they’re getting 3D-printed earhole covers from XO Armor Technologies, which provides on-site, on-demand 3D printing of athletic wearables.

The Auburn, Alabama-based company has donated its version of the earhole covers to the equipment managers of programs ranging from Georgia and Clemson to Boise State and Arizona State in the hope the schools would consider doing business with XO Armor in the future, said Jeff Klosterman, vice president of business development.

XO Armor first was approached by the Houston Texans at the end of last season about creating something to assist quarterback C.J. Stroud in better hearing play calls delivered to his helmet during road games. XO Armor worked on a solution and had completed one when it received another inquiry: Ohio State, which had heard Michigan State was moving forward with helmet inserts, wondered if XO Armor had anything in the works.

“We kind of just did this as a one-off favor to the Texans and honestly didn’t forecast it becoming our viral moment in college football,” Klosterman said. “We’ve now got about 60 teams across college football and the NFL wearing our sound-deadening earhole covers every weekend.”

The rules state that only one player for each team is permitted to be in communication with coaches while on the field. For the Spartans, it’s typically Chiles on offense and Turner on defense. Turner prefers to have an insert in both earholes, but Chiles has asked that the insert be used in only one on his helmet.

Chiles “likes to be able to feel like he has some sort of outward exposure,” Kolpacki said.

Exposure is something the sophomore signal-caller from Long Beach, California, had in away games against Michigan and Oregon this season. Michigan Stadium welcomed 110,000-plus fans for the Oct. 26 matchup between the in-state rivals. And while just under 60,000 packed Autzen Stadium in Eugene, Oregon, for the Ducks’ 31-10 win over Michigan State three weeks earlier, it was plenty loud. “The Big Ten has some pretty impressive venues,” Kolpacki said.

“It can be just deafening,” he said. “That’s what those fans are there for is to create havoc and make it difficult for coaches to get a play call off.”

Something that is a bit easier to handle thanks to Bush and her team. She called the inserts a “win-win-win” for everyone.

“It’s exciting for me to work with athletics and the football team,” she said. “I think it’s really exciting for our students as well to take what they’ve learned and develop and design something and see it being used and executed.”

Michigan football emphasizes return of discipline under new regime

Michigan football emphasizes return of discipline under new regime


play

The buzzword continued to come up in Schembechler Hall, from each one of the captains.

From Bryce Underwood to Jordan Marshall, Rod Moore to Trey Pierce − Michigan football players around for the previous regime and in the case of the latter two, the one before that too − each said Wednesday, March 25, that there’s a noticeable difference within the program under new coach Kyle Whittingham.

For Moore, a sixth-year player who will likely become a third-time captain when the official leaders are voted on later this summer, he recognized the vibe.

“I would say it’s kind of a similarity to coach Harbaugh’s regimen,” he said. “It’s a lot more strict than the past two years, and the weight room has kind of been a night-and-day difference than the past two years. We feel a lot stronger, a lot more progress.”

The Wolverines finished winter conditioning and Whittingham graded it with an “A+.” Hope is often the dominant mode at this time of year and adding a new coaching staff to what’s generally a positive time creates little surprise that the Wolverines are raving about the new system.

But beyond the platitudes and clichés, there are tangible examples. Take Pierce: The projected starting defensive tackle has trimmed his weight to 300 pounds while adding muscle mass to his overall frame.

“Something new that we have now is that whenever we start meetings, there’s like a loud air horn that goes off throughout the whole building,” Moore said. “The past two years, we would start the meeting at 2:30, but now we start the meeting at 2:25, even though it’s a 2:30 meeting. Just everyone being five minutes early. The coaches are holding everyone accountable in the meetings, going to class.

“Just the little things that makes a team great, not just the big, broad things that everyone sees.”

There was an implication from everyone, though nothing said explicitly, that the past two seasons featured little enforcement. Most players would show up on time for lifts, but there were those who didn’t, with few repercussions.

“It’s the little things,” Pierce said. “Guys being late for lifts, guys not being where they’re supposed to be, whether it’s [missing] class. Just enforcing that a little bit heavier, that type of thing. … A lot of coaches say that when you’re being recruited in front of your parents. But for [Whittingham] to say that in front of the huddle after practice and say, ‘That’s why I’m here,’ I would say, ‘OK, he cares. He gets it.’”

Throughout the offseason, some who’ve spent time inside the facility said the weightlifting sessions had notably more juice. The past two years felt like a carryover of the previous years in terms of style, but accountability and discipline wavered.

Now, with Doug Elisaia leading the strength and conditioning room, there are different philosophies.

Practices are a bit shorter these days – two hours – but as Marshall said, “I don’t stop moving at practice, like, we’re always doing something that’s not only going to help with us competing with teams, but our conditioning.”

Marshall believes it can take the Wolverines to the next level, he said.

Just more than a week into spring ball, players are oozing confidence. Not just in their skills − the running back room is deep, the wide receiver room has as much raw talent as at any point the past decade, the offensive line returned multiple key pieces, the secondary added depth and the defensive tackles feel underrated − but in mindset.

U-M had early, demanding lifting sessions during winter conditioning, with a clear organization.

“It introduces that factor of toughness, like we’ve been through this at 6:30 a.m., 6:15 a.m., all these days in the grind together,” Pierce said. “It improves team bonding, and puts you in the headspace of, we’ve done harder stuff than this, and nothing can break us.”

The difference between winning and losing can often be razor-thin. Will this pay off when it counts during the season?

“If I can trust you to do things maybe you don’t want to do,” Marshall said, “then I can trust you on the field when it’s the fourth quarter and we have one minute left.”

Michigan school bus driver wins national hero award


LANSING, Mich. (InvestigateTV) — A Lansing school bus driver has won a national award for going above and beyond behind the wheel.

Jackie Wilkerson-Brown, known as Miss Jackie by students, transports children to and from Lansing’s Gardner and Lewton schools. She recently became the first recipient of the 2025 School Bus Driver Hero Award.

“I was like, seriously, seriously, seriously, and I just started crying,” Wilkerson-Brown said.

The award was presented by School Bus Fleet Magazine. Teachers and parents nominated Wilkerson-Brown for the honor.

Known for being fun and firm

Wilkerson-Brown is known for being fun and firm with students. She hands out candy and leads students in games like the name game on rides home.

“Being a mirror bus driver is just sitting in your bus and, ‘Sit down, stop doing that, stop jumping over the seat,’” Wilkerson-Brown said. “You have to sometimes get up out of your seat and face-to-face with your children.”

Posters of positivity line the inside of her bus.

“I keep it on my bus, and I just try to remind the kids that, you know, smile,” she said. “Kind vibes, happy lives.”

‘Unbelievable honor’

Patrick Dean, president of Dean Transportation, said the recognition is significant.

“This is an unbelievable honor for Jackie,” Dean said. “Jackie exemplifies everything it means to be a superhero bus driver.”

Todd Sharp, operations manager for Dean Transportation, said Wilkerson-Brown treats students as her own.

“When those students step up on her bus, she treats them as her own. They’re her children while they’re in her care,” Sharp said.

Wilkerson-Brown said she loves her job.

“I’m trying not to get emotional, because I love my job, I love what I do,” she said. “If you call my phone right now, the message is going to say, ‘Hey I’m busy being awesome.’ So, because I am awesome, I am awesome, and then to receive this award, and then it came and I’m employed by Dean Transportation, oh, my God, it doesn’t get any better than that.”
