Drop a stone into a deep borehole and the answer takes longer than expected — three or four seconds of silence, then a small wet plonk that echoes its way back up the shaft. That delay is the whole point of the sound, and it is what makes most stock recordings of wells feel fake. These 7 borehole and well clips preserve it.
You will find single stones dropped down shafts of different depths, the hollow drip of seepage off rock walls, a longer water-level fall after rainfall, and the deep resonance of a voice or shout echoing inside a stone-lined well. A dry tumble of debris falling without water at the bottom rounds out the set. Horror and mystery edits use the longest delay takes for unease — the audience hears the pause before the splash and starts to imagine the depth. Cave and underground scenes pull the same echoes for spatial sense. Free to download, no signup.
