Had exactly the same problem with my seat belt buckle. You think its the seat at first but if you put your hand next to the buckle and underneath it, you can feel it vibrate at the same time as the noise and on mine was coming from the rubber gaiter underneath the seat belt receiver buckle.
To fix, simple spray a load of WD40 into the top of the buckle and it will find its way right down and into the rubber gaiter at the bottom. No need to take anything apart.
