Living in a tiny urban apartment, this is a problem I am interested in a solution for. However, I always read that such solutions might block the noise for the toilet-user, but not for those outside of the toilet. I'm curious as to the efficacy of a white noise machine versus this device and, specifically, if either is really effective. It's an interesting solution, OP, an I commend you for your efforts - but I fear $150 is going to be a difficult sell.

Pretty easy to test with a phone running mynoise set to white noise.

I’ve heard the same. I expected the product to be a speaker to mount on the top of the door to play music on both sides of it, or something.

Enters the bathroom.

The speaker starts blasting “Eye of the Tiger” into the foyer.
