I don't live very far from SeaTac International Airport which hasn't be a problem; until their adding a 3rd runway. I'd been using a sleep mask and some compact sound suppressing ear muffs, came up with the idea of combining the two into a single product, and then wondered if somebody already had; and THAT'S how I discovered Hibermate. I LIKE the product and all its adjustment capabilities, but am still getting accustomed to sleeping with it,
