<p>Disclosed is a low-cost wind speed measurement device capable of preventing accuracy loss. The disclosed wind speed measurement device is provided with a sound wave detection means (1A) which, attached to a moving body such as a bicycle (B), generates sound waves from an airflow (e.g. the wind) and detects said sound waves, an extraction means (band-pass filter) (14) which extracts a specific frequency component from the sound waves detected by the sound wave detection means (1A), and a wind speed calculation means (S7) which calculates the wind speed on the basis of the specific frequency component extracted by the extraction means (14).</p> |
