%X Any search effort for gravitationalwaves (GWs) using interferometric detectors like LIGO needs to be able to identify if and when noise couples into the detectors output signal. The critical coupling likelihood (CCL) method has been developed to characterize potential noise coupling and in the future aid GW search efforts. By testing two hypotheses about pairs of channels, CCL is able to identify undesirable coupled instrumental noise from potential GW candidates. Our preliminary results show that CCL can associate up to ∼80% of observed artifacts with SNR  8 with local noise sources, while reducing the duty cycle of the instrument by 15%. An approach like CCL will become increasingly important as GW research moves into the advanced LIGO era, going from the first GW detection to GW astronomy.
