The first Snormuffler was designed by Frieda Magrib in an attempt to quiet her husband's unusually loud snoring.
Though the principle (that of using a muffler to reduce sound wave intensity) worked in theory, the actual device never really performed the way it was intended. Because the air intake valves necessary for breathing would, of course, be open during inhalation, no snores were ever muffled since the sounds associated with snoring occur during inhalation.
Even though the Snormuffler failed as an anti-snoring device, it did, however, make an excellent "laugh muffler" useful for those who often find themselves needing to laugh at inappropriate times. Frieda got earplugs.
