Is Your Audio System Winterized?

[@damayor62]

Outstanding as always Lou. I guessed humidity would be the topic but I was surprised when you also talked about the air pressure and its impact on turntables. Fascinating stuff. Thanks and keep up the great work.

Thank you for your comments and please feel free to tell others about this channel and the other 210 videos. I am sure there is something there for nearly everyone.

I’ve owned an LP12 for over 25 years. In the winter months, the hinges on the lid are not strong enough to hold the dust cover up. In the warmer months, the dust cover staying up on its own is never a problem. Just something I have lived with for decades. I don’t know if it’s temperature or humidity that makes the seasonal difference. Doesn’t matter when I am listening to an LP as the dust cover comes off for that almost always.

Oh, that's priceless Nate. I also take the dust cover off myself on all turntables that have one when in play. I am suspicious of the humidity and the effect on the springs or dirt that may lie within. That's my best guess. Thanks for contributing to the page. There's always something to be learned in the comments and, well, you gave me another to think about. Please tell others about the channel as there are over 200 videos currently available.

Seasonal variability in air pressure is around 1%, or around 10-12 mB, more pronounced at higher latitudes, almost nil closer to equator. (source Seasonal Variations in Atmospheric Pressure, Partial Oxygen Density, and Geomagnetic Activity as Additional Synchronizers of Circannual Rhythms). Variability due to tidal pressure is around 3 mB (source: NOAA). Daily variation of high and low pressure systems is around 50 mB. So seasonal variability in air pressure is about 1/5 of daily. Ergo, if you need to adjust VTA, then in agreement with daily weather. This is a famous reductio ad absurdum to show the flaw in the original "argument". Second, air pressure has nothing to do with gravitational forces of stylus on groove. Even assuming you are right with the seasonal VTA changes (I also doubt that), the rational is completely baseless.

Well, thank you for all of your explanations. For those who want to experience the difference, simply try it. As the air grows colder, it becomes more dense. So, I'll go with your criticism to some extent but I am not taking about gravity at all but how we hear.
