Physics and HiFi

Cooling should reduce the humidity as well as cool the room. If it isn’t doing so the unit may be oversized.

I’ll get about a 20% drop in humidity from cooling alone without setting dry mode. But that’s taking it from 90-100% down to a still high 70-80%.

The units are correctly sized for every room.

Going back to the OP, Peter Belt, or rather the apparent credence placed by hifi press on his, erm, illuminating ideas was directly instrumental in making me decide that the hifi press could not be considered as a serious source of information and hence worth my money buying and time reading. However it has at least provided decades of amused recollection and joking when with other hifi enthusiasts having similar memories, as we suggest to each other putting a piece of paper under the left rear foot (butt arguing which foot of which bit of kit sounds best) or placing a saucer of water - full to the brim in a strategic position but arguing about where it would sound best, etc.

For a very entertaining read I came across this article:

Try this, worked for me back in the day on my LP12. No, seriously.

Cut a one inch length of sellotape, stick half it on to the edge of the outer platter so that the other half sticks out.

We used to get know-it-alls in the shop all the time with a rolled up copy of some publication or other. Asking for special green felt pens for marking the outer edges of CDs and all sorts of stuff. Then they’d challenge any brand like Naim or Linn that had a contrary recommendation to out-there tweaks.

I must have said the following phrase 100 times to customers, “with all due respect, please bear in mind that [insert publication name here] is absolutely not in the hifi industry. They are in the journalism industry.”

There’d probably have been a market for “CD pens” at £25 each, getting one of those promotional pen suppliers to provide suitably printed ones at 1000 for about £100….

Hi FR, thank you very much for this compliment.

Actually, at the time I was quite irate that the expensive thing I had bought was ‘Not Fit for Purpose’.

FYI, The phrase ‘Not fit for purpose’ is quite useful for retail consumers in UK consumer law if you want to get a manufacturer or service provider to listen to your complaint - but only if the complaint has provable legitimacy.

Hence the need for me to get deep into measurements to establish the legitimacy of my complaint.

Do you think it can make a difference in sound going from 20 C , 2% humidity, to 28 C, 2% humidity?

If you mean relative humidity, which is the normal consideration when discussing humidity in human terms, 2% would be highly unpleasant - your lips would crack, nose itch like crazy. eyes feel sore - I’m not sure what effect on hearing, but you probably wouldn’t be very focussed on listening anyway, and a few degrees change in temperature might not be noticeable…

Ah ok, didn’t knew that. So what be an average rate of humidity, in Paris, no rain, full sun.
15%? ( 28C).
So my question remains, with a more correct humidity rate. ( average).

The ‘Andouillette’ interconnect?

Or, you could measure it :wink:

Yes, but British andouillette, so not AAAAA , but FAAAL).

I know it’s a British cable, but forgot the name. They make powerblocks too.

I am lazy bro. I tried quickly google, but it gives either the rate advised by doctors ( between 40 and 60% inside a room) , or this graph, but it’s calculated on rain rate.

I don’t know any details re Paris, but as a rough guess I would expect between maybe 30% and 70% relative humidity most of the time, except in very wet and hot thunderstormy weather when it might be 70-100%.

Apparently it’s 55%. I thought it was much less.

It’s the capital city of France. HTH

Ha ha! I might have thought it was a town in Texas, but my estimate of typical humidity range may then have been different…

The relative humidity is irrelevant. It isn’t a measure of moisture content.

Air at 55%RH at 28c has approx 60% higher moisture content than 55%RH at 20c.

When humidity is spot on.
