Background vibration and your system.


I have been interested in vibration and its effect on my audio system for probably forty years. I remember getting some platforms with inner tubes that had to be pumped up with a bicycle pump very early on. Well, I think they may have helps a little... but pumping them up drove me crazy. Since them I have used pucks of all kinds, and Black Diamond Racing composite platforms and cones, springs, and the best has been the Silent Running Audio Ohio Class vibration platform that I had made specifically for my Linn LP12... which was well worth the price. 

I used to be a geologist. So, I have wanted to get a seismograph for a long time. About a  year ago I purchased one. It is on the Raspberry Shake network with thousands of others. They have confirmed the correlation between times of day and remote events being transmitted into the house. Evenings and especially Sunday nights tend to be the quietest. I have seen thunder claps, cars and trucks driving by being recorded as well as not too hard footfalls on my concrete floor.  

On the map below, you can see the Pacific Northwest. Each icon is a seismograph that can be viewed.  The red dots are small earthquakes which can be seen and correlated with the recording of any of the seismograph by clicking on a red dot and then the seismograph. This page has a tremendous amount of different functions if you just explore it. 

I recommend folks that are interested, move around the map and find one close to your house. You may be surprised how much activity there is.

check this out...can’t find the whole vid.

"are clock crystals sensitive?"

the best thing one could do really is to ’float things’ on some thick low duro jelly squishy elastomer whatever.

A lot of the stupid stuff that gets sold for hifi ’isolation’ didn’t do anything for the likes of what you saw in this vid. 

There is a pretty cheap fix for vibration actually.

Low durometer (about 30) sorbothane pucks...There's a website out there for correct weight distribution on it. Yes,  it will stick and stain if you don't do the following....get a plastic bag, cut 2 pieces of the plastic out of it and sandwich the sorbothane puck between..to prevent staining, etc...Works way better than some vulture priced crap.

I've noticed some big improvements on dacs.

if the tremors  caused settlement/foundation issues, etc, you have other bigger problems besides hifi to worry about, of course.

 

Isolation of what component are you referring to? speakers? clunker amps? If so, do your townsend or whatever.

I was specifically referring to dacs with the linked vid. After trialing everything including things that may have been priced as much as your speakers, yes, i decided at one point that these elastomers were the way to go, if deployed correctly for weight.

These guys did a lot of R&D, huh? Did you see their R&D facilities (a garage maybe? or something bigger) perhaps? test equipment? data? anything?

 

You can really knock yourself out comparing vibrapods, all the different elastomer pucks, cones of different materials... etc. I have a couple drawers of this stuff. I spend probably hundreds of hours or more doing detailed comparisons over the decades.

A very generalized conclusion I came to is that the very expensive stuff... like Townsend, Silent Running Audio, and Black Diamond work better than cheap stuff. It’s really simple, companies like these that do Research and Development can/must produce products that are very notably superior to someone who simply chooses a substance and makes it into a form. Companies like Townsend and Silent Running have outstanding reputations for a reason. Folks that can afford them hear the difference. 

Not exactly young and starving, but, I will always accept donations and free gear from very rich cats like you. 

I was young and poor once and worked my way through inexpensive alternatives. Nothing wrong with that.
