Tests confirmed Valderzak's significant hearing improvement. But his doctors think they have a medical explanation for the "miracle."

"He had conductive hearing loss, caused by fluid in his middle ear, as well as loss due to nerve damage," said Dr. Ross Fletcher, chief of staff at the VA Hospital. "A combination of a drug he was taking and the earthquake event itself likely led to him losing the fluid and gaining back his hearing."

Dr. Jennifer Smullen of the Massachusetts Eye and Ear Infirmary said the shaking itself might not have been enough to clear the fluid from Valderzak's inner ear.

"But if somebody was startled, and yawned or yelled, sometimes that's enough to clear some fluid out from the ear drum," she said.

In any case, recovering the ability to hear after going months without is a gift.

"People are usually very grateful, very happy, very surprised," said Smullen. "They'll walk around looking at things that they'd forgotten made noise. It's very gratifying."

Valderzak had adjusted to his hearing loss with the help of a special microphone and a crash lesson in lip reading. But the situation was far from ideal.

"The devices helped, but by the time I got them all hooked up, everyone had left and I was talking to myself," he said, adding that lip reading meant he could only talk to one person at a time. But now he can talk to all four of his kids again.

"Why did it happen at that time, with my whole family there? There was God's touch in there," he said.

75-Year-Old Veteran Calls Earthquake a 'Miracle'

Valderzak's doctors had just ordered him new, high-powered hearing aids. Now they're set to the lowest possible volume.

"It's a complete pleasure because the event was unexpected and brought a lot of joy to him and his family," said Fletcher. "This changes his outlook and his family's outlook."

Valderzak has been a patient at the VA Hospital since it opened in 1967.

"It's a pleasure for us to take care of him," said Fletcher. "He called it a miracle, and from his point of view it is. We think we know why it happened but it's still a miracle to him."

Valderzak, a veteran of the Korean and Vietnam wars, still has a tough fight ahead of him. But the earthquake has given him the boost he needed to take on cancer.

"All these things I've been through to get my hearing back, I've seen plenty of doctors, and none could figure out why I couldn't get it back," he said. "It was a miracle. And now I'm going to beat cancer, too."
