How to make DIY isolation feet – quick and easy | Audio Tweak

The whole idea is to make really quick and easy DIY isolation feet under glass board and DIY amplifier monoblocks (Article yet to come). This is just temporary solution until I make proper isolation platform. This is pretty much all from leftovers including wood, foam and glass boards, so please don't laugh.
 
I like the effort.
Whether or not you may hear a difference...of course that's a different subject.

Presumably this is for people with hollow wood floors or like that.....where the floor vibrates with loud audio passages (sound vibration)......minimizing vibration transfer.

Because with a stable concrete floor....any (too) soft isolation feet will in fact result in a GAIN of vibration in the unit sitting on the feet, because the ground is more stable (heavy) than the unit sitting on top of it.
The lighter object will succumb to vibrations before the heavier.

Imagine a bowling ball sitting on a hollow resonant floor, then vibrating the floor with large sound waves. The ball may move and/or vibrate with the floor.
Now imagine a bowling ball on a concrete floor with large sound waves.....nearly no movement of the ball.

A bowling ball sitting on a vibrating resonant wood floor, but on top of some resonance-absorbing padding.....decouples the two, and seems much better than nothing at all.

Hi I absolutely agree, do yo mind if I quote you in the article?

hey, I really love this kind of 'foot work' 😀 and have done my share of it too
these small things will always be great fun, absolutely

but it was surprice yesterday, when I noticed this 4 pack with 38mm rubber feet ... 2.50 EUR

Hi,

FWIW that thickness and stiffness of foam is effectively
only a gasket and will provide no isolation whatsoever,
unless very lightly loaded, not the case as shown.

rgds, sreten.


I know you obviously need much thicker layer or squash balls / soborthane, this is more o less fun and really was made from scrap material. I don't really believe in vibrations on particular components such as amps too much.
 
Believe? Don't you have ears? It's hilarious you are writing articles on "audio tweaks".

When you have your own blog, then you can write articles about what ever you want mate. I bet you are one of those people who don't have money and rather put some stupid crystals and antivibration pads instead of buying / building proper amp with proper parts. Antivibration thingy is the last thing for me.
 
My VPI turntable has cone feet.
It's meant to sit on a grounded surface that's won't succumb to inner room vibrations.
Realistically, what are the chances of that happening, in reality ?
Prob not often.

(OK, I know a guy who added concrete foundations under his speaker placement and turntable.)
