The audio clip titled "01-Yawn" begins with the unmistakable sound of a deep, drawn-out yawn. The noise is a blend of a low, resonating hum and a high-pitched sigh, creating a perfect embodiment of tiredness and sleepiness. It's the kind of sound that may make the listener themselves feel the irresistible urge to yawn. The audio is a clear representation of a common bodily function, often associated with fatigue, boredom, or the need for sleep. The sound slowly fades away, leaving behind a quiet, calm atmosphere, suggestive of a peaceful, sleepy setting.
