I'm going to incorporate a waterfall into my existing stone retaining wall to mask some distant highway noise and neighborhood traffic. The waterfall will be in a perfect location to mask the traffic noise when in the yard but it's located about 40' away from my bedroom window and facing the opposite direction. I'd like to amplify or spread the waterfall sounds closer to my window by using an outdoor microphone installed near the waterfall and place two speakers on the opposite end of the deck. I've found one old post where someone has done this but was unsuccessful in getting a response. The waterfall will have a main fall of appx. 5 feet into a large in ground basin with an additional smaller fall of appx. 2'. Any suggestions on microphone/speaker setups or suggestions would be greatly appreciated.
