Definition
口哨儿 (kǒu shào r) is the noun for the sound you make by blowing through pursed lips — it's the thing you 'blow' (吹). 哨 (shào) alone usually refers to a physical whistle (the device) or a sentry, not the lip-whistle sound. 呼啸 (hū xiào) is a verb for the roar of wind or vehicles, not a human action.
noun
