I mean, if you introduce copper instead of the material used for sure the frequency will grow. My question is how they are able to reach that low frequency, which materials and which suspension isolation was used? | |

| Feb 18, 2016 at 21:15 | comment | added | Trebia Project. | My question is how currently we are avoiding the thermal noise. The link provided (and all the links included in the answer) refer to the current level of noise and only describes the approach for the sismic noise. My question is , how are we able to reach that level of noise? The answer is incomplete | |
