If you're looking to quiet splash water, there are a few things you can do. One is to add something called a splash guard to your pool. This will help to reduce the amount of water that's able to escape the pool and make noise. Another option is to install sound-dampening panels around the perimeter of the pool. These will help to absorb some of the noise from the water. Finally, you can simply keep your pool clean and free of debris. This will minimize the amount of splashing that occurs and help to keep the noise down.
