Sound reduction expert Cork

rom

I live in Cork in a new build timber frame house. It's in an estate and just over 300m from a motorway. The upstairs bedrooms that are facing the road suffer from road noise quite a bit.

Clearly it's triple glazed windows but I am looking at options to reduce the sound as much as possible.

- Vents are firstly quite poor. They are just a pipe with a grate either end so they leak noise. I have put pipe insulation into them that seems to help they a lot as they were just echoing the sound before.

- Now it seems like the sound is hitting the window but I feel the it may actually be the wall is not solid enough to deflect the sound so another layer of sound proofing plasterboard could be put on them and the exterior wall and ceiling.

- But of course I don't want to do this if it makes little difference but I do feel like it could simply be the exterior wall is the issue.

So thats why I am looking for an expert.

You can get sound deadening curtains. It may not alleviate the problem but it would ultimately be the cheapest step in a sound deadening exercise.

This is an exercise that an "expert"might take a lot of your mula, with little results.
.
Noise reduction is a tough ask, because once you hear it and let it impact on you, it becomes tough to get it out of your head.
.
Research has shown that people beside railway lines have interrupted sleep when the trains don't run on the regular schedule.
Anyway,
what's the outside wall structure?
.
TG will help but may not solve it
.
Have you blocked the wall vents with the insulation?
.
If the whole estate is impacted get onto your local TD to have a roadside barrier fitted

Sound will get in wherever there is an air gap even through the roof.

Your first step should be to have an air pressure test done on the house to find your air leakages and take it from there.

It sounds like you have a hole in the wall ventilation strategy. Not very efficient. I wonder would switching to DCV help with the unwanted noise? You could call a few DCV/MHRV companies and chat to them about this.

Acoustic airvents, foam internal duct. Take out metal ducts if you have them and replace with these.
