In this audio titled "OWI_Four Taps", the dominant sound is a series of four distinct, hard knocks or taps. Each tap resounds with a substantial thud, almost as if they're being delivered on a heavy, wooden door. The rhythm of the taps is steady and deliberate, creating an atmosphere of anticipation or possible urgency. The audio leaves you with the impression of someone trying to gain attention or entry, demanding to be heard.
