After much demand, the Gravity Spy team has added examples of what Gravity Spy data sounds like to their field guide! The frequencies of gravitational waves detectable by LIGO are almost identical to the pitches of sound that humans can hear. Therefore, LIGO scientists oftentimes convert signals to sound for a different means of analysis.
The same can be done for noise sources in the detector. In Gravity Spy, volunteers have been scouring images of these noise sources, known as glitches, to better understand the noise that afflicts the detectors. Now, you get a different sense for the data by hearing sonifications of the various different types of glitches. Head to the field guide of the Gravity Spy project to take a listen!
