In the audio titled "First Impact Sound", an initial sense of anticipation is created as the listener is immediately introduced to the rhythmic pulse of an air conditioning unit humming in the background. Suddenly, a trash can, likely metallic, is hit with a drumstick, creating a sharp, percussive bang that reverberates through the soundscape. The impact of the stick against the metal trash can gives a distinct thud, marking the first significant sound event in the audio. It's a raw, unrefined sound that has a certain musicality to it, merging elements of everyday life into a unique percussive rhythm.
