The best and most efficient way to soundproof your place is to start with the windows. Soundproofing of windows adds layers of glass to help deflect sound. There is also a sound dispersing air layer sandwiched between the glass panes to aid in noise reduction. If you currently have aluminum frame windows installed, just switching to vinyl will benefit in noise reduction. Making sound sensitive changes to your windows can help keep outside noises just that — outside. Where a triple-pane window upgrade will require a change out of your existing windows, some specialty soundproof window options can be installed behind your windows for a less invasive fix.
