To begin , it is important to review some of the most common DIY window soundproofing options and their limitations :
DIY window soundproofing limitations
When it comes to window soundproofing a host of DIY methods are well intentioned but have only a limited effect :
Blocking the window with furniture Although this option is free , placing sofas or other furniture next to the window in an effort to absorb some sound waves will do little since sound has complete access through most of the entire window .
Caulking gaps between the wall and window The caulking will reduce some sound that may enter through small gaps between the wall and the window ’ s borders , but the effect will be minimal at best .
Weatherstripping Installing or replacing weatherstripping constructed of materials like foam , rubber , or vinyl can reduce some external sound entering from any small gaps around the perimeter of the window . This does not address the main source of external noise intrusion , the window itself .
