No, it does not. I can still very acute my very good ears, a murmur I hear with the best will not, even if I drappiere the stones and austeste, a murmur, does not want to adjust in the best of intentions. Even at full power the pump raises no splashing one, as it says in the description and is promised. It flows more than that. Whereby, halt. Flow did not at the beginning. When I turned on the fountain, then I needed a mop, because I did not have cute little, handy indoor fountain, but a fountain here. The beam went up to the ceiling ... It is therefore advised caution if you take it at the first time and after each cleaning operation. I do now every time a stone over the outflow to prevent such a thing. The pump is quiet, but not be replaced if it is broken, because the lamp LED connected to the pump. In fact, this fountain is a disappointment and a clear bad buy for me. I'll probably invest in a more expensive wells, one is the bigger and really splashes and not only flows. Update 06 June 2015: After the third full cleaning, the lamp LED adopted. To view more than beautiful this fountain and not a more than absolute Billi product. I am more than upset. The money is better spent on a more expensive wells, as in this cheap junk, where the LED is adopted after the third cleaning. And the pump then probably after the fourth or fifth cleaning. The positive reviews I can not understand clearly. This fountain is not worth the money and does not even deserve one star, because I have too often excited about this thing. On the one hand on the Wasserfontänte that I have after each cleaning and the connection of the pump, and now the broken LED lamp.
