I have had my j pouch for 3 years now I have not found a way to quiet the noises. I am sure it's a fine balance of diet since certain foods may make you more gassy. I'm not willing to change my diet because it doesn't bother me that much but you may want to try eliminating some things to see if it's something you are eating. I have heard people post here that say taking probiotics help. The noises do however come with the territory now at least to some degree no matter what you do. After all, we are minus a big part of our digestive system.
