Kaldkõlve

Kaldkõlve is a term used in Estonian to describe a phenomenon related to the sound of wind. It refers to a specific type of whistling or humming sound that can be heard when wind passes over certain surfaces or through narrow openings. This sound is often associated with natural environments, such as forests or open fields, but can also occur in urban settings where wind interacts with structures. The precise pitch and quality of kaldkõlve depend on factors like wind speed, the shape and texture of the object obstructing the wind, and the surrounding atmospheric conditions. It is not a scientific term with a precise definition but rather a descriptive word used in everyday language to capture a particular auditory experience. Listeners may perceive kaldkõlve as eerie, pleasant, or simply a characteristic sound of a windy day. Its presence can sometimes indicate an approaching change in weather.
