This will basically prevent the falling water from making contact with the water’s surface, instead falling on to a soft object. My first suggestion is to put something soft in the pool to essentially break the water’s fall. Add something to cushion the water’s fall I recommend reading through them all before trying one, as some are more suitable for use in aquariums, but all are suitable for trying in outdoor water features. It’s fair to say that you’ll never make a flowing body of water completely silent, but trying some of these methods will make a difference. Now we can move on to some suggestions for making a waterfall quieter. Take some time to think about where your waterfall is and how this might affect what you can actually do. Fish are very sensitive to chemicals, and even a bit of plastic might be enough to kill them. The other thing worth considering, particularly if this is an indoor problem, is whether there are any living creatures involved.įor example, if you’re trying to reduce the noise of falling water from a fish tank pump then you need to be very careful with what you do. Echo and reverberation can make the waterfall sound louder than it actually is. If your waterfall is part of an outdoor water feature, there’s probably plenty you can do to make it quieter.īut it’s also worth considering if there are any surrounding walls that the noise can bounce off. What Kind Of Environment Is Your Waterfall In?īefore working on your waterfall, it’s worth taking a bit of time to understand its environment and how this might help or hinder your solutions. While it’s not strictly necessary to understand this process in order to reduce waterfall noise, it does help in understanding why the solutions below help. But obviously the more this happens simultaneously, the louder it’ll be. This process is the same regardless of the volume of water that’s falling into a still body of water. ![]() The water droplet basically becomes a miniature Helmholtz resonator. In short, this means that smaller air pockets resonate at a higher pitch than larger ones and that the pitch increases as the air pocket decreases. Gravity then restores the water’s surface equilibrium, and in the process forces the trapped air out.Īny sound caused during this process by the water vibrating resonates at a frequency that’s inversely proportional to the volume of the air trapped under the surface. ![]() This bubble then pops, releasing the air, which creates a sound.īut if the water’s surface doesn’t completely close around the drop before the drop’s surface collapses, you end up with a kind of teardrop-shaped pocket of air beneath the water’s surface. If the water droplet doesn’t have enough energy to break the surface tension, the water closes around the droplet, which traps some air inside the “bubble”. This process may or may not be strong enough to break the water’s surface tension. When this comes into contact with the surface of the still water, the kinetic energy becomes vibrations, which convert into sound waves.īut in more detail, the water droplet pushes the water’s surface down and penetrates into the water to a degree. The science behind waterfall noise is quite interesting but can become complicated when you start involving fluid mechanics.Īt the most basic level, water falling has some amount of kinetic energy from its movement. While many people find the sound relaxing, it can be irritating if you need to concentrate on something important or are trying to sleep.īut why exactly does water make noise when it falls? The most common sources of waterfall noise in the home are either backyard water features or fish tanks. Hopefully, by the end, you’ll have a good solution for this distraction. In this article, I’ll look at the science behind waterfall noise along with the best ways to reduce it. This will drastically reduce the noise it makes. You’d be best to use something soft like a sponge, but you could also fit a ramp so the water pours rather than falls. The easiest way to reduce waterfall noise is to put something at the bottom to break the water’s fall. If that’s you then you probably want to know how to reduce waterfall noise. While I love the sound of falling water, I know some people can find it irritating. ![]()
