Sound room humidity

Keep pumping it in until the static shocks stop happening! 55% in my space. 

Yes, I maintain 56% 24/7 year round even when we are away.

Wow 55% seems high folks? I guess it depends on where one lives. 

At 55%, the air becomes too thick and deadens the sound a bit in my experience. 40% is ideal in my house of stereo and I never have any static pops on my vinyl rig.

It probably varies to some extent with climate.  56% is my number in South Florida.  This is semi-tropical.  40% would not be practical here.  The air is thick here in more ways than one.  Consider the musings of our President and Mr. DeSantis.  ;-)

No. Humidity is not really an issue unless it becomes extreme. Here in Florida with the house always closed and the AC system always set to dehumidify we are lucky to get under 60% RH. I see the same concern on camera forums where people are buying dry cabinets just because they bought a new camera and are new to the hobby. Same for stereo stuff. I'm still using gear from the 1980s as are most of my friends who are into audio. Just not an issue unless you are above about 75% regularly and that also becomes an issue for structures :-) 

Personally I find 55% feels too humid.  I'd keep it at 50% here year round if I could.  :) 

It depends on the temperature.  It's called "relative" humidity.  A 50% relative humidity at 80 degrees contains much more moisture than 50% relative humidity at 65 degrees.  The higher the temperature, the more moisture it can contain.  Dewpoint is a better measure, particularly when determing what it "feels like".  As to how this applies to audio, I have no opinion/knowledge.

I watched an interesting video on Rick Beato’s site, he was interviewing a sound guy who did live concert sound. He mentioned that they must take humidity into consideration when setting up the sound in the live event as it effects the sound quite a bit. He gave no humidity levels, but it makes sense.

Interesting, never really thought about humidity changing sound. Usually do it for comfort, static reasons. 

Here in the PNW, we have had a colder winter, humidity has dropped into the 20%, my skin hates it, my plants hate it, my TT really hates it. Been running my humidifier 12+ hours a day on high. Got the humidity around 45% now. Can't say I notice a sound difference. But I have thinking "my system sounds really good" lately. 

@abnerjack Good point. 55-60% at 65F-70F is where I average. 

Well I had heard a number of arguments both ways. From too much humidity can change the sound to needing to get humidity up for static electricity and even other things so I was curious what guys on this forum were doing. I think I will shoot for about 35 to 40 percent and see how that works out. Thank you for all your comments. 

35-40% is what I attempt just for health/comfort and I monitor the LR and both BR’s.

Don’t care for 50%+ sound wise, but is it the sound waves or my sinuses/ears?

my humidity set for health and comfort only ...

In addition to relative humidity, I try to keep listening sessions “constant “ by running two air ionizers in a medium size room for a half hour, beforehand.

Don't forget to use a room air filter. Those pesky flakes disperse sound waves like countermeasure chaff.
