I was hoping to install a backdraft damper into an extractor fan vent duct. Can the backdraft damper be placed anywhere in the duct? If the duct is long, does the backdraft damper have to be near the exit point? I was hoping to install a new American variety called Tamarack Technologies Cape...

maybe it's the sound of the sea getting into the pipe and distorting the sound.

There is also a rumbling sound in the stairwell of the apartment building. It doesn't affect me, but I am curious to know what is causing it.

There could be a slight wind. I will soundproof the entire room. Then I don't need to work out what is causing the noise.

Would it be silent if there is no wind blowing through A constant rumbling noise

What sort of extractor fan vent exit cover is best if you don't want air entering the vent when the extractor fan is switched off?

The extractor fan is not switched on.

If there is an extractor fan vent duct in a ceiling that is making a noise all the time, how can this be remedied?

OMG

OMG

I think there could be a long run of ducting

When the extractor fan in the ensuite bathroom is on, the flaps on the vent outside don't open. Why is this?

How do you access the outside of the third floor of an apartment building in order to replace a flap exit vent? Would a cherry-picker work?

I might not, because there is a lot of noise in the vent when it is windy

The extractor fan is on the third floor
