purpose of ceiling cloud

[raven46]

I've seen posts here about ceiling clouds before, I did a search but could'nt find what I really wanted to know, also I remember someone posted a link with a long write up on acoustic treatment but I cant find that either

I've had a look about the net and found some site that sell clouds or showed how to build them, I'm thinking of building one but before I do I'd like to know how they affect sound and how necessary they are

Links to previous threads/sites would be great

I think it serves the same purpose as placing panel elsewhere in the room. It's just placed between the monitors and listening position and extends past listening position to the rear. Absorbing reflections off the ceiling I guess. Just passing what i remember.

Floors and ceilings are parallel reflective surfaces sometimes causing an echo or slap-back effect, cloud(s) absorb much of this. If used over drums they also help tame the harshness of cymbals and can help with some boominess in a room. The size and number will depend on your room and the reflections you need to control.

That's right. In a room with a low ceiling, it can also make the ceiling appear to disappear. I have a drum room with just over 6' ceilings, and installing clouds completely changed the sound.

A cloud above the mix position does two things: It absorbs "early" reflections and, if it's thick enough, also adds some bass trapping for the floor-ceiling modes. More on early reflections here:

Thanks guys

Ceiling clouds also helps when you want hard wood floors and not carpet, basically swaps the non-reflective surface to the ceiling. I agree with pandamonk, the clouds make the ceilings disappear when stuck with a low ceiling room.

I am a big fan of ceiling clouds and hard floors.

Does it occilate, appearing one moment, disapperaing the next...?

Yes. It disappears during periods of sound in the room. It appears during periods of silence. But you can't hear it then.
