"Noises in the mountains have nothing in common with the sounds you hear everywhere else. Isolation is not the only cause of this phenomenon, because in the middle of the sea or in the middle of the desert it is something completely different. The sand and water move, the mountains are motionless, although it is said that they may have flown away in the past. From there, no doubt, this silence, so heavy, produces a spoiled space, a hardened vapor that absorbs all noise." (Gilles A. Tiberghiend)
