There is a lift.

Constant whirring

There are some faint noises in the apartment which are disturbing at night. I can't work out where they are coming from. Is there any way I could find out, so that I can do something about it.

How do you short circuit it? How do you open it? Do you take it off the wall?

Hi It initially started to work but only after several attempts at placing a card into the slot. Now it doesn't work at all.

The lights in my apartment are operated by a key card light switch near the entrance. This is similar to what you find in hotels. It has stopped working. How can I get it working again? The lights won't come on without it, as far as I know.

I don't mind the initial outside noise which is the sea and wind. I mind what it is turned into - some kind of dull, lower pitched reverberation due to sound bouncing around the room. I am not even sure if this sound is due to reverberations. Maybe I could put some kind of acoustic foam on...

Such people don't mind preventing much air entering the room from outside.

That will let the noise in.

If an extra pane of glass is put in with a large gap between it and the other panes, that should reduce the external noise. However, if trickle vents are put in for ventilation, some noise will get in as well.

Triple glazing could be a solution to reducing external noise. But how do you solve the ventilation problem?

Could this contraption be used with coal instead of coke to melt gold?

Hi I am curious to know how this works. Is it really just blowing extra air into a charcoal hearth, thereby raising the temperature to 1064 degrees C?

No. It will be done by a specialist company.

I live in a block of flats with 8 flats. There is one lift. The lift goes from the basement to ground floor, first, second, third and fourth floor. How much should it reasonably cost to replace the lift suspension belts?

You mean like this? What is being forced in? Is it just air? Why does it go down to 22k is it charcoal ash? .

It's for a work of fiction

Is it possible to melt gold in a coal fire in a fireplace? What precautions should be taken?

Whichever ones work best to block out noise.
