Underwater Trunk Fill Sink Human Knock

This underwater sound captures the unique ambiance of a trunk filling with water, sinking slowly to the bottom, and a human knocking on its surface. The sound begins with the gentle splash of water as it fills the trunk, followed by the creaking and groaning of the wood as it strains under the weight of the water. As the trunk sinks deeper, the knocks from a human hand become more urgent, echoing in the enclosed space. This recording is perfect for adding realism to scenes involving underwater exploration or survival.
