The audio begins with the muffled noise of a tense calmness, a deceptive peace that abruptly shatters under the impact of a heavy, thunderous explosion. The sound resonates with a big boom echoing through a stairwell, its metallic structure rattling violently under the sheer force. The echo reverberates, amplifying the intensity of the blast, and bounces off the hard surfaces of the stairs. The distinct clanging of metal on metal suggests debris hitting the railings and steps, adding to the chaotic symphony of the explosion. The audio concludes with the gradually fading echoes of the explosion, leaving behind an eerie silence that speaks volumes of the devastation.
