Again, you haven't seemed to have described why getting rid
of high frequency noise (and high frequency signal) is appropriate to remove the noise of weather from climate.
For 2012, the use of new body sealing techniques including improved weatherstripping design, and additional expanding foam pillar separators, help
reduce high frequency noise by 3 dB within the TL's interior.
if we remove
high frequency noise by 6 month smoothing, essentially leaving seasonal or longer differences but removing short term (e.g.monthly) noise, the SNR rises to 5.1.
A significant enhancement for the 2016 QX60 is the addition of acoustic glass for better insulation
from high frequency noise.
Figure 6 of Houston 2011 indeed indicates such error bands (but even more importantly, it
shows high frequency noise which is almost an order of magnitude larger).
The internal structure
eliminates high frequency noise interference from the digital circuitry, while shielded power supplies and a large power transformer resist the radiation of noise and vibration.
They then dissected a dead elk and found a throat structure that would allow the animal to «whistle» through its nostrils to create
the higher frequency noise, they write today in the Journal of Experimental Biology.
The new floating structure of the PCU's reactor greatly reduced vibration and
high frequency noise.
