The more tiers and places for water to flow from on a fountain the more water flow you will hear. Also, the sound will be louder if the water level is lower. If you are looking for a classic piece or art that is as timeless as it is elegant, tiered outdoor fountains may be exactly what your space needs. These are the type of water elements that you could see creating focal points in magnificent gardens at palaces and castles many years ago. Today they are available in a variety of styles and sizes, so you don't need to have acres of lush vegetation to showcase one.
