If an extra pane of glass is put in with a large gap between it and the other panes, that should reduce the external noise. However, if trickle vents are put in for ventilation, some noise will get in as well.What is the ventilation problem?
That will let the noise in.Opening a window normally helps I found
Such people don't mind preventing much air entering the room from outside.Don't most people seal trickle vents to stop draughts?

You are overthinking.However, if trickle vents are put in for ventilation, some noise will get in as well.
I don't mind the initial outside noise which is the sea and wind. I mind what it is turned into - some kind of dull, lower pitched reverberation due to sound bouncing around the room. I am not even sure if this sound is due to reverberations. Maybe I could put some kind of acoustic foam on the walls. I wouldn't know what to put on the walls. I am allergic to carpets.There is a way to have Triple Glazing and ventilation ...Simple answer is dont have Trickle vents! Use a PIV or MHEV system instead, or use acoustic vents ( but they will still let a certain amount of noise in)
