Sound of fountain can became a noise in a housing complex. We evaluated 10 water sounds in an experimentation room at 50 dBA : only 3 sounds were pleasant. At 60 dBA, most water sounds turned out to be unpleasant. We laid a water sound over a traffic noise and souaht pleasantness. AIl water sounds improved the pleasantness. The improving degree reflected the evaluation scores of independent water sounds : a small falling water on water gained the highest score whereas jet out sound gained the lowest. Choice of the pleasant water sound seems important in improving environmental noises of a housing complex.
