Etymology: "Noiseproofing" is simply the gerund and present participle of "noiseproof," a verb formed by adding "-proof" to "noise." The pattern is an old and productive one: "proof" as a suffix meaning "resistant to" or "protected against" has long been attached to nouns to describe materials and objects that withstand something, as in "waterproof" or "fireproof." Here the sense is plain: to make something resistant to sound from outside. The word therefore needs little explanation beyond its parts. "Noise" comes from Old French "noise," meaning a quarrel or outcry, and "-proof" supplies the idea of impermeability, so the combination describes treating a space or material so that sound cannot pass through it.
