Read about them here
at Silicon Acoustics, and from the manufacturer, Ear Specialty Composites, here
I must say that I'm a little incredulous as to their claims of 7dB noise reduction
. I mean, that's staggering. I imagine those kinds of numbers are only possible when much of the noise generated is from vibrations being transferred to the case rather than air noise. I wonder what kind of effect they would have coupled to low speed Panaflos or Papsts?
Also, the manufacturer website indicates that they also make grommets for mounting harddrives. Again, they claim the grommets produce a 7db reduction from idle or seek
. How can these numbers possibly be true? Silicon Acoustics doesn't sell theses hard drive grommets, so I have no idea how you would purchase them even if it were true.
I e-mailed back and forth with the manufacturer a month or two ago trying to find another retailer for these, or some independent review, but I never heard anything back from the sales rep they put me in contact with.
Anyway, if these things are capable of producing any kind of significant (even 2-3db) noise reduction, I'm sure tons of us here on SPCR would love to have them. So, does anyone have any experience with them? Any chance MikeC can get some review samples?
