no it won't, unless you choose to sleep on the kitchen worktop.
It will be on the other side of the wall. There is a short, direct run to the external wall, next to the window.
I guess that most of the time you will not have the cooker hood running while you are asleep.
You can conceal the duct with wall cabinets. If you want, you can have a row of top-boxes (about 350mm high) and run the duct inside them, cutting round holes in the ends rather than notching from the back which would weaken them. They are various widths, you can probably get 1000mm, 900mm, 800mm, 600mm and 500mm to fill the distance.

but you can get much cheaper ones.
you could either get doors to fit out your whole kitchen matching, or, cheaper, flat slab doors in white, or painted to match the walls.
