Pressure Cooker Sound

Hi all,
My T is in the left ear, but during the night, T appears in the right ear too. The sound in the right ear is totally different, like a pressure cooker sound. Like this: "bru..bru...bru...bru..."
During the day i can't heard this sound.
Anyone have these symptoms?

 

Mine today is like a pressure cooker ,both ears ,dropped down when I hoovered ,but again it's clawed it's way back up .Think weather doing it ,terrible here today .Annoying hissing this is. Can't ignore it ,it's a grabber of a day ,due to its loudness .Odd you get it at night I only have it day time ,can be heck of a long day .

 

Yes! I had the same faint sound of a pressure cooker. That bru bru bru sound just before its about to whistle..I showed it to my mom when she was cooking and she was like " wow, you must be kidding me" lol

But that distorted sound completely went away in my case in a couple of months . its now replaced with very faint eeeeeeeee
