100% Moisturized White Noise Machine
The sound source for this calibrated white noise generator comes from a (modern) Roman bath in Germany. Imagine a large vaulted room, various basins alternating between warm and cold water, high, arched ceilings papered with mosaics, and a continuous flow of water from pools. The beautiful ambience of the surroundings is just as relaxing and encompassing as the hot baths themselves.
Compared to classic waterfall noise, this noise generator is more reverberant. The higher-frequency range is generated by the sound of the running water echoing from the walls and ceiling, while the lower range is produced by the extractor system, blowing the moisture away.
