My hubby passes gas all the time...not funny anymore

Hello all...
My husband is 59 years old, has recently dieted and has lost 35 pounds.
So far so good right? He doesn't consume alcohol at all and drinks a lot of water. I cook pretty much healthy foods and the only junk he eats is ice cream. For as long as i have known him, he has had a gas problem, from the business end. He has been checked by a Doctor, had had a lower GI in the past and all checks out fine. Now, i think he does it to piss me off.
When he farts, he doesn't try to cover it up or try to squelch it some how, he just lets them rip!!!! It sounds like a tommy gun going off. Then he laughs and seeks out my reaction. It's like when he feels the need to tear one off he will look to see if i am in close proximity, then he lets it go. He then looks at me again to get a reaction and he laughs. I have listened to this for so long now that it's disgusting to me. He farts in front of people that may be in our home, and says, oops, sorry, if ya gotta go, ya gotta go. He does the same thing in bed at night. They echo thru the whole bedroom. I have asked him to please go into another room when he feels the urge, especially when we are watching TV he will let them go one right after the other, even the dogs leave the room. I look over at him and all he says is "what" with a stupid look on his face. The he wonders why i go into the bedroom to watch TV at nite, at least i don't have to be serenaded by the one man wood wind instrument band. There have been a few times when we were getting frisky with each other and will will cut one, i get so mad i loose the moment, then he wonders why we didn't finish what we started.
I know we all fart, it's natural. But i don't think that one has to be so deliberate with it. He knows i get upset, but he thinks it's hysterical. I was talking to him on the phone just the other nite and he did it, it was so loud over the phone. He talks to several people thru out the day and evening and he will do it while he is talking to strangers. I know they can hear it because i heard it over the phone myself.
No need to check his diet, it's fine. We eat legumes because they are good for you, but not all the time. We eat greens as well, but not every nite. These foods are gasey i know, but we don't have them all the time.
So...any suggestions? It's sort of funny but then it's not, especially when you have to listen to it 100 times a day. Sounds like a mouse on a honda.
