underwear invention

This is the one of my inventions, that I have always wanted to sell in Japan. The acoustic dampening pad. This idea came to me while watching a TV show about Japan. I'm not saying anything bad about Japan or the Japanese people, they value etiquette and cleanliness. I created a small pad that you can put between your bum cheeks, so that when you fart, the sound is dampened or absorbed. As a bonus, any offencive odours are reduced. I am working on a prototype that can release a fresh sent to cover any strong odours. This can be very useful for someone with intestinal problems. My invention can also be marketed in the Americas or in Europe.
