We have 1 reports of a deep low-frequency sound from Rožňava. The dominant description is tone with irregular breaks. Below are the words of the people who hear it there.
„Hlboký nízkofrekvenčný tón pripomínajúci vzdialený subwoofer. Nerytmické, nesynchronizované prerušenia — raz hučí dlhšie, raz kratšie. Počuteľný v noci aj cez deň, vnímaný od detstva (~1991).“
Every additional report from this place helps. The more independent testimonies from one location, the stronger the evidence — and the better the source can be pinpointed.
