Sound proof blinds

I asked DH (sound engineer) he says have you thought of changing your window to triple glazed? You can get sound deadening panels but they are not as effective.

I can honestly say they don't work .

What type of windows do you have? I’d go for upgrading them if possible because I doubt the blinds will work. If you have older/single glazed windows, secondary glazing is excellent at reducing road noise.

We bit the bullet and got secondary glazing. The biggest things to reduce sound is a decent air gap and different thicknesses of glass. Triple glazing could make resonance worse if the glass thicknesses are all the same, as certain frequencies are broken up and others therefore feel more prominent to hear.

Anyway we have over 10cm gap and glass is 6.4mm acoustic glass and can still hear a little noise sometimes. I think blinds wouldn't do much.
It was expensive at £500 for the window BUT we have huge huge windows over 2m wide. Smaller windows might be a more reasonable price. We used clearview secondary glazing who have an online quote calculator that's accurate. Just a thought.
