Ceiling Fan

How about using vertical centrifugal fans, then covering them with thick cloth bags when not in use?

I've got a ceiling fan in the bedroom  plus one in the Conservatory and to be honest they would interfere with listening.

In the lounge where my main system is I use a Dyson AM09 and because it is on the floor where the cooler air is it is very effective and when on low speed it  doesn't interfere when listening to music it has a remote so you can switch the various  functions swivel , cold to hot with thermostatic control, fan speed and timer etc. 

I had a standard fan in the dining room they just seem to move warm air about this was replaced by another AM09 this morning not cheap but I feel well worth it.

Second the Dysen option. Nearly silent when on low with the stereo not on, when the music is playing zero impact.  If you do hear some interfearance remote off it.

I did read some reviews of the Dyson but they were quite negative -just moving warm air around, which is obviously what the ceiling fan will do. 

However if you guys are recommending it I'll revisit the option.

Thanks for your help.

Some ceiling fans are virtually inaudible, others quite intrusive, though I have no idea of brands. Of course, they don't cool the room, but can make it more comfortable through wind-chill effect if temperature is high and assuming the occupants don't mind the feel of moving air.

I wish I could convince SWMBO that a fan only 'works' when people are in the room... by the wind chill effect evapourating sweat and thus removing heat from the body, however she just doesn't get it... the fan is on for hours in an empty room doing nothing except moving warm air around. 

You could be forgiven for asking 'Why don't I turn it off ?'... to which I would reply in two parts:

1. You have obviously never met SWMBO

2. The power consumption of said fan is miniscule in comparison with the multitude of NAIM boxes that are running in another room (and whereas she may not be in a position to evaluate the power consumption thereof, she is perfectly able to count the number of green lights !)

Worse than that, all the electrical energy used by the fan turns to low grade heat, actively heating the room up even more (albeit only by a small amount!).

The other half has recently taken to joining me and reading and listening casually whilst I listen properly. She has commented the room is very warm and asked why I don't fit a ceiling fan.

You could inform 'the other half' that the room would be cooler without the heat produced by her body, reading and casually listening when there's proper listening to be done. Whether this suggestion has long-term domestic merit, you'll have to determine.

That same heat produced by her body, might help your system perform in the Bedroom!

I would be careful, with that one!

There you have it, get a central airconditioning system and pipe cool air around the house, you won't need a fan. You can still disagree on the setting of course and your energy bill may suffer a bit.

I don't know. There may be something positive to be said for a little perspiration between a couple alone in a room, music playing.

My KDK ceiling fan is always on albeit at the lowest setting but still able to keep me cool in our tropic temperature.

You still have a fan, just at the other end of a pipe!

I like ceilings, but I wouldn't call myself a fan.

  brilliant!

Or you could take the green option.

I live in a warm country (Portugal) and from my experience ceiling fans are terrible. Vertical fans are good and big ones you place on the floor tilted up are even better. My mom has one and it can cool you even if you place the thing 3 meters away or more. If you use it full throttle it produces one hell of a racket...it's loud, really loud.

I have to admit, I have only vague memories of what you are aluding to Joerand.

You might like to investigate the installation of an A/C system Steve. I am averse to raised heat and humidity and had a full system (to cover a 4 bedroom house) installed in 2014. The Mitsubishi room units mounted high on the wall are neat, unobtrusive and (most importantly for us audiophiles), whisper quiet in operation.

It might not be as expensive as you think. Only the price of one black box from Naim!

Email me (address is in my profile) for further information if you wish.

I was going to suggest the same and also to consider the ceiling mounted units from Mitsubishi too. However, if you do decide to go with a fan, I really would be surprised if it appreciably affected your room acoustics which was, I believe, the original question.

We also considered floor mounted fans but much preferred the ceiling fan approach and have to respectfully disagree with the negative comments about them. In my experience the wind chill effect works very effectively over a large area of the room shifting a high volume of air, and with the right fan it can be super quiet, and look very contemporary, plus it has a zero footprint with no cables on the floor. 

We used a 103cm Eco Neo II 4 Blade Ceiling Fan with Remote manufactured by CasaFan. It has a long life DC motor and is almost inaudible on all of the slower 3-speeds of the 6 available. Any noise is just wind noise. We leave ours on in the bedroom all night and can't hear it. My hearing is still very good. 

An online sizing tool is available from the manufacturer to help determine the correct specification for your room. If you do go down that route I recommend that you check for damage in transit when delivered as the motor is rather heavy and if there's been any rough handling in the supply chain, the weight of the motor assembly can bend the cage that it's mounted in. Ours was bent slightly but the unit was quickly and efficiently swapped by the supplier for a new one.

It's worth reading the instructions 3-times before fitting and flow to the letter as it's only possible to fit the way it's described in the literature - don't ask me how I know!

Clearly ineffective to use Max_B for cooling in this case.

My original question was meant to see if/how much electrical noise would be introduced into the system rather than the sound of the fan/wind generated would interfere with listening.

Since posting, I now wonder if the wind generated would interfere with the tracking of my cartridge. Too many doubts in my head now to proceed with the fan route. And an AC system for the 10 days a year it's actually uncomfortable in that room seems a tad excessive.

Thanks for the replies though guys. 

And yet, seriously, I think that being the ceiling the largest, untreated, most reflective surface in the room, I think that very hardly a ceiling fan could have a negative effect of any sort  on the sound. Any object – still or moving – able to break and diffract sound waves should, in my humble opinion, be beneficial to the sound.

If the fan is not plugged into the same line as the stereo, perhaps the better.

Best wishes,

CD
