An object that produces a white noise (like a fan, or maybe a radio on a lower volume) that is used to make sounds audible in a very quiet environment not quite as noticeable. Noise hampers can be used to make it harder to hear you doing something you
don't want others to know about.
Noise hampers explain why so many
people like to
masturbate in the bathroom with the shower running.
While Tyrone and Shelly were having sex, Shelly used her
fan as a noise hamper so her
parents wouldn't hear her moaning.
I had to find a noise hamper so I could fap in
peace.
