(CBS)  It's the sound that can stress out any marriage.  Snoring can keep frustrated partners up all night long.

But one company, Ventus Medical, says it has found a solution.  

A new snore therapy product called Theravent, just received FDA approval for sale over-the-counter.

It's like a big band-aid that seals tightly around your nose.  The so-called microvalves allow you to breathe in freely, but restricts the airflow when you breath out.

Ventus Medical says it reduces snoring by 76-percent. 

Kiet Do tried it. "It feels like you're wearing a scuba mask and takes some getting used to.  But after a few minutes of fussing and scratching, you can hear the results."

Do's snore went from a loud snore to a hissing sound.

"Because it's actually creating pressure when you breathe out,  it actually pressurizes the airway.  So instead of havaing a floppier, smaller airway, the airway is distended and expanded and less likely to vibrating.  And that's how Theravent treats snoring."  Said Dr. Raj Doshi from Ventus Medical.

There were, however, a few minutes where do's snoring overpowered the device, but it was still  muffled.

Theravent costs less than a dollar a night.
