Abstract
A wind gauge apparatus and method. An illustrative embodiment includes a microphone positioned to engage wind pressure from a first relative direction and a controller coupled to receive an audio signal from the microphone. The controller compares the audio signal with plural threshold values, representative of wind pressure levels, and determines a first wind pressure level incident upon the microphone. Filtering and gain controls are used to condition the audio signal output from the microphone. Plural microphones are employed to allow that detection of wind direction and magnitude about a compass of directions. Digital signal processing is employed to process data. In an illustrative embodiment, the wind direction and magnitude data are used to recommend a golf club size adjustment and a golf swing direction adjustment to the user, who has taken a measurement of the wind with respect to a reference golf swing direction. In another embodiment, a temperature sensor is added and the controller calculates a wind chill factor.
