I miswrote previous.
So with LIGO you could not place and playback any audio system in the same room as LIGO ..without IT being corrupted by the transmission of any shear wave or compressive wave..For LIGO to succeed outside its container it must duplicate that same containment where ever it travels. In your home with electronics that generate wave types from transformers motors and speakers LIGO would be a storage device for such wave types. Those devices would include diaphragms contained inside headphones and any device that has a power source or motor to drive those. They all generate shear waves and compressive waves as part of their motion .
Think about the possibility of eliminating all forms of motion..compressive and shear..then what Geoff?.Can you hear that? Anything.....Tom
I'm not sure what you’re going on about. LIGO’s extremely comprehensive vibration isolation system(s) are intended to reduce background mechanical noise to the point where the experiment is sufficiently sensitive to differentiate gravity waves, which are extraordinarily minute, from the background noise. What is the background noise I’m talking about? Well, in the case of LIGO - way out in the boondocks - that’s primarily seismic type mechanical noise produced by Earth crust motion (microseismic vibration), the primary energy of which is located down around 0 to 3 Hz. Since the interferometer I.e., laser shoots down a tunnel around 3 km long to a mirror and back, there's plenty of room for error. Therefore, extremely low resonant frequencies Fr for the isolating systems are required. So, if you could construct a LIGO at home you could obtain superior audio performance. How much is good enough? You might have to deal with acoustic waves (which are also mechanical in nature) and any residual noise on the top plate of isolation devices however that is produced with damping.
LIGO Also employs very robust vacuums around test equipment, recall vacuums are excellent at NOT transmitting mechanical noise. When I was in the exhibit with Mapleshade he had a brand spanking new Nachamichi Dragon CD player with separate DAC. The player had the capability of forming a relatively good vacuum seal around the CD transport when a CD was played. The entire Nachamichi system was isolated on my 6 degree of freedom Sub Hertz Nimbus Platform, the top plate of which employee special and highly effective dampers to deal with residual vibration on the top plate. Sort of a precursor to LIGO you could say, since that was just around the time LIGO began about 20 years ago.
