What type(s) of noise? If it is popping, there may be a freshness indicator on top of the jar. If it is hissing or similar, that jar may not be sealed, and there is some sort of gas exchange, whether ingress or egress.
Either way it is due most likely to temperature or atmospheric pressure changes or fermentation.
