Study on the threshold of winds speed at which one begins to perceive airflow

Part3: The forearm of young female subjects under different wind temperatures

Abstract

A subject experiment was conducted in which the forearms of young female subjects were exposed to airflow at different wind temperatures to measure the threshold of wind speed at which they began to perceive airflow, and a subject experiment was conducted to measure the threshold of cold sensation in the same subject's forearms. As a result, the effect of the threshold of cold perception on the threshold of wind speed at which they began to perceive airflow was smaller than the results for the male subjects. Although extrapolated by the regression line, it was found that wind speeds of 0.4 m/s or higher are required to perceive airflow without cold sensation. At ambient temperature of 22℃, subjects were found to perceive airflow even at wind speeds of 0.1 m/s or less, and at ambient temperature of 30℃, no subjects perceived airflow even at wind speeds of 0.2 m/s.
