Sound room humidity


Hello all. I am wondering if any of you use a humidifier in your sound room and level of humidity do you try to maintain? Is 35% a reasonable number? Thank you.

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.
