    Interesting. I have a humidity meter in my room and it is usually between 55 and 65 percent. Currently showing 62% but it is a very damp day. Maybe I should get one of these gadgets? House is 118 years old, don't know how old yours is James?

    Hi Martin, my house was built on 1866 so fairly old. I never thought it was particularly damp but sometimes I saw condensation on the walls. It also felt a bit cool. The transformation is very noticeable even after 3 days running the dehumidifier. It feels a different atmosphere, dry and much more pleasant. The model I have in the link to Brian also has an air purifier function which also helps. You can set the humidity level you want it to go down too and it switches off automatically when water tank is full.

    in summer the air is warm so can hold much more water, hence high values. its in mid 60's here at moment and wet outside. Cold air cant hold much moisture so winter is usually much lower. also your central heating is on and dries it even more. Plants scattered around house is a good way to control moisture, along with the dehumidifier. 45/50 is probably your ideal, but unlikely to get it in peak summer months.
    My breathing suffers badly if it gets too high or too low; especially low. you also get lots of static when in low 30s of winter.(I have to touch earth with my stick before touching anything)
    As to your point with audio, there will be changes at certain frequences at different humidity levels, and SoS is also affected. Water vapour is lighter than air so when moist its less dense and thus SoS is faster.

    I'm sold, will order one on Monday. I dry clothes indoors so will help with that even if nothing else. If you had condensation on the walls it sounds like you definitely needed one.


    I'll report back on any SQ differences.

    If you play records, you may find a dry atmosphere encourages static. Not necessarily a good thing.
    It is impossible for anything digital to sound analogue, because it isn't analogue!

    I agree too low humidity does encourage static. However my static has reduced considerably the closer I get too 60% humidity. I was over 65%.

    There must be an optimum level for humidity as there is for room temperature which is about 21oC. Cartridge suspension material is calibrated at this temperature.

    Static only bothers me here when i get around 40 and lower. I try to keep it about 45 in winter. Today its rained all day but temp in house is about normal 22/23c and humidity around 58/65 depending on which metre i believe. breathing today at that level is good and sounds from stereo are fine.
    not sure if you will distiguish much change with 5 or 10% change but you might

    True, but the change is much smaller than you would think:



    At 20 degC the change is negligable. Even with a change of humidity from 0% to 100% the speed of sound at 20 degC shanges from 343.5m/s to 344.8m/s, a change of less than 0.4%.




    I would put the perceived improvements in SQ down to the atmosphere being more comfortable for the listener, and so the experience is more enjoyable.
