Learn English – “I hear a noise” vs “I hear noise”

A bunch of individual noises (a cow mooing, a dog barking, a bird singing) when occurring at the same time, can be considered collectively to be just noise.

I would only talk about noises when you mean to make a distinction between them either in time or by source.

You were making a lot of noises in your sleep last night.

This means at multiple times during the night you made some noise.

You were making a lot of noise in your sleep last night.

This would more likely be interpreted as you making noise in a more continuous way throughout the night.

I can't think with all this noise.

Here noise means the sum of all noises being heard. (The lawnmower, the traffic, the dog, the television, the neighbors, etc.)

I would rewrite your sentences:

The queen-size wooden bed always makes noise when we lie down on it. We had not noticed this issue until we moved in. Even when I am very careful as I turn over in bed, the noise still annoys my wife and she always complains about it.

In the context given, the most correct and common way to say it would actually be

Stop being noisy.

Since they are already making noise.

Don't make noise.

Is correct, though it when used in that particular context it sounds a little strange to my (native, American) ear. If you were in a situation where you wanted to prevent future noise,

Don't make noise.

or

Don't make any noise.

would both be perfectly fine to use. As far as noise being counted vs non-counted, the difference between 'noise' and 'noises' usually comes down to whether are multiple types or sources of noise. The difference between 'noise' and 'a noise' is usually whether the noise is sustained or brief.

For example, if there is a crowd of loud students in the hallway, you can say:

I hear a lot of noise in the hallway.

If there is a crowd students, and someone using power tools you might say

I hear a lot of noises in the hallway.

If the hallway is otherwise quiet, but someone loudly dropped a book it would be

I heard a noise in the hallway.

You could even use 'a noise' when referring to a sustained noise, though it would usually be coming from a single source, such as a dripping faucet, instead of a group of talking people. Generally, because 'noise' is so flexible, whether you use 'a/any noise' vs 'noise' and 'noise' vs 'noises' the sentence will usually sound correct.
