Hearing aid wearer are familiar with the need to change batteries often so information about Ethans’s discovery to extend the life of hearing aid batteries has been well received. The discovery was the result of Ethan Manuell’s science project and his interest came because he wears hearing aids himself.

Soon-to-be high school freshman Ethan has never allowed his hearing loss to slow him down. The first runner-up of his 8th grade class and an accomplished musician, Ethan used his own hearing loss and experience with hearing devices to inspire his research for his school’s Science Fair project.
His study, “The Effect of Wait Time on the Lifespan of Hearing Aid Batteries” was called “a discovery that a PhD at an academic mecca would be proud of” (KARE-TV). Ethan found that hearing aid batteries can last up to 85% longer when left exposed to air for five minutes before being inserted into a hearing aid.
His discovery has the potential to benefit 7 million hearing device users. Ethan was just hoping for a good grade on his science project.
In fact, he went on to the regional and Minnesota state science fair and even won a prestigious US Naval Science Award.
