The 46-year-old actor said she used air traffic control headphones to keep the sound at bay, reported People magazine.
"His snoring. It's really a problem. I have like air traffic control headphones. Noise-cancelling headphones. But sometimes it still bleeds through," Silverman said.
The "Saturday Night Live" star said she could not really do much about the problem as she loves the actor.
"What can I say? I love the guy," she said.
Silverman and Sheen have been in relationship since 2014.
