Preventing traffic noise through bathroom vent

[mxo]

Hi all,

I am getting my bathroom refitted. The bathroom is top floor and facing onto a busy main road with lots of traffic. There isn’t currently an extractor fan.

Initially the plan was to fit the extractor fan into the wall, but I’m concerned this will allow all the traffic noise to come in.

Alternatively, I could put a vent tile in the roof and pipe a ceiling extractor fan to the vent, but I’m concerned this could still allow traffic noise in.

Does anyone have any suggestions for solving this problem?

There are acoustic vents and shuttered extractors for this purpose

Are these typically installed as roof vents or wall vents?

There are baffles and foam products that will reduce the passage of sound through any duct, but they will also reduce the efficiency of the extract fan.

A wall fan with a mechanical shutter to close when not in use may be a better solution.

Would something like this in the wall do the trick, or would I also need to look at a special duct or something else? - https://www.extractorfanworld.co.uk/airflow-icon-eco15-extractor-fan-72683501-210-p.asp

My mate has the exact same one as that in his downstairs loo. It works very well.

Does he have it fitted in the wall or ceiling? And it keeps traffic noise out?

If you want to keep out traffic noise, brick the hole and vent elsewhere, the roof as you say probably your best option.
The downside, is of course cost. A more powerful fan, ducting, extra work involved.
But you'd be well annoyed if you'd gone for a shuttered option, only to be extremely disappointed that 1mm of thin plastic doesn't block the noise from motorbikes and lorries.

I might get one of those. Don't have traffic noise, but my wall fan faces my neighbours front door and driveway, so often hear them.

I put in a wall fan as the hole was already there (old air vent) and was the easiest and cleanest way to put a fan in.

Are sound-proofed vent tiles available on the market, or are they all a standard model? This is for a slate roof.
