Anyone reading this: go around your system and at each point, the system with the metal end of a screwdriver while touching the handle of the screwdriver to your skull. This will help you hear vibrations. You will find the noisiest points. Wrap these points in plastic tubing. | |

This isn't that surprising I suppose, given how the remote head works. We're going to try wrapping the lines in plastic tube. Will report back if/when it does/doesn't work. | |

Added question about transdution channel of the sound

| Sep 13, 2014 at 23:32 | comment | added | David Z | I think this should not be closed, since it is pretty clearly about experimental physics - but I don't feel it would be appropriate for me to unilaterally reopen it. If a few other people did so first, I would definitely vote to reopen. In the meantime I wonder if another meta post would help matters... | |
| Sep 13, 2014 at 21:43 | comment | added | DanielSank | @innisfree: Also, if there's doubt about whether or not to close, which there clearly is given your previous comment, shouldn't the benefit of the doubt should be given to the question? | |
| Sep 13, 2014 at 21:41 | comment | added | DanielSank | @innisfree: I tried an Area 51 proposal for a dedicated low temperature physics site, but several folks are complaining that the types of questions proposed for it really should be asked here. I think a lot of people agree with this as evidenced by the existence of the experimental-technology tag! "Physics" does not mean "parts of physics which don't actually involve building things." The implied definition of "physics" expressed by voting to close this and similarly oriented questions is a constant source of displeasure for experimentalists. That should be enough of a reason to not close it. | |
| Sep 13, 2014 at 21:37 | comment | added | innisfree | Well, on the one hand, this isn't a question about physics, but, on the other, you want a practical piece of information that only a physicist might have. I can see cases for and against closing. | |
| Sep 13, 2014 at 21:30 | comment | added | DanielSank | @innisfree: Yes, it is about soundproofing a particular specialized type of equipment used only by experimental physicists. Suppose I were to ask about how to stabilize a laser; would that be accepted here? Given the links provided above by dmckee, I think closing this question doesn't make sense. | |
| Sep 13, 2014 at 21:27 | comment | added | innisfree | I voted to close this question because I thought it was about soundproofing. Is it about soundproofing? | |
| Sep 13, 2014 at 21:23 | comment | added | dmckee --- ex-moderator kitten | To be sure the question makes no particular reference to an experimental context, which may have something to do with people's decisions. I would just plead for a little more time taken on such decisions. | |
| Sep 13, 2014 at 21:17 | comment | added | innisfree | @dmckee I will be the first to confess that I don't know ANYTHING about experimental cryogenic systems :S Maybe I was too hasty to recommend closing the Q | |
| Sep 13, 2014 at 20:37 | comment | added | dmckee --- ex-moderator kitten | I am curious if any of the close voters know anything about experimental cryogenic systems? The usual set of meta posts apply: meta.physics.stackexchange.com/q/5553 meta.physics.stackexchange.com/q/2948 and meta.physics.stackexchange.com/a/4146/520. | |
