What range of atmospheric pressure changes can be sensed by the body?

Some of my joints swell up when atmospheric pressure drops before a storm. It only happens sometimes, and I’m not sure why. Is this influenced more by the delta in pressure or by how quickly the pressure is changing?

The ears when they are hearing sound can detect changes as small as 20 micropascal. And you could go ridiculously high because if your body is obliterated by an explosion, you did technically notice the pressure change.
