If you look at the lengths LIGO had to go to in order to eliminate background noise to even be able to theoretically detect gravitational waves, it seems very unlikely that a comparatively crude technology from the 80s could have achieved the same things. Like modern lasers or squeezed light states, which were mostly theoretical back then. If I remember correctly, Weber's device was claimed to show a huge amount of events per year, which would indicate tons of GW sources in our neighbourhood. LIGO and the rest of modern astronomy have since disproved that.

Sometimes noise turns out to be signal (see developments leading to Cosmic Microwave Background [0]). At this stage in gravitational wave detection is it well founded to consider noise as noise instead of information we cannot yet understand?

Noise always has different sources, and when you eliminate noise you should always be conscious of the source. There should be a gravitational wave background analogous to the CMVB. Detecting it would be a sensation.
