These barely reduce noise at all. Even with these earplugs situated in my ears correctly, I can still hear myself typing this review, and I can also hear my husband talking at a normal level in another room. The only noise they're capable of blocking is the sound of air whooshing through the heater/AC registers. I did give these two stars, though, because it is true, as stated in the product details, that you could store grains, snacks, fruits, and nuts in the transparent plastic box after running out of earplugs. :)
