As a football fan, you maybe remember the image of last month’s Super Bowl might have been quarterback Drew Brees’s fourth-quarter touchdown passes which put the New Orleans Saints ahead for good. However the most highlight was Mr. Brees’s 1-year-old son, Baylen.

Baylen, worn by his father’s coaches on the sideline, wearing something what looked like the headphones. However, they are actually low-cost, low-tech earmuffs, which are used to protect his hearing from the stadium’s roar.

Specialist point out that more than 15 minutes of exposure to 100 decibels is unsafe. And the noise in a football stadium can reach 100 to 130 decibels.

The noise which is dangerous to an adult is even more dangerous to a child. Because a young child’s ear canal is much smaller than an older child’s or an adult’s, so the sound pressure entering the young child’s is greater. The shorter length of the ear canal increases dangerous noise levels in the higher frequencies, which are crucial to language development.

As hearing loss, which accumulates slowly over a lifetime, is neither painful nor disfiguring, it goes unnoticed. The stigma attached to Hearing Aids which is often considered a sign of age or weakness. But it seems to carry over to hearing protection.

Protecting the hearing of very young children is not easy. They can’t avoid the noise by themselves. And Earplugs are too big for tiny ear canals and too easy to put into the mouth. Meanwhile, they are hard to insert — even adults do not always insert their own earplugs correctly.

Enter protective headgear, like the earmuffs worn by Baylen Brees are sold by a number of companies. But most are not meant for infants.

More than half of customers have special needs, like autism or sensory disorders. For other children, the purchasers are typically grandparents, who sometimes say that their grandchildren cover their ears at fireworks or air shows, or that they themselves suffer from hearing loss.
