Why would a ceiling make a whistling noise?

A ceiling may produce a whistling noise due to air leaks or drafts, often caused by gaps around Windows, doors, or ductwork. When air moves through these openings, it can create turbulence, resulting in a whistling sound. Additionally, changes in temperature or pressure can cause materials in the ceiling, like ducts or vents, to expand or contract, contributing to the noise. Regular maintenance and sealing of air leaks can often reduce or eliminate these sounds.
