Why Boston Homes Need Sound Proofing
Boston ranks among the loudest major cities in the United States — fourth nationally by transportation-noise exposure, with 12.9% of residents living with 60 dB or louder average-day road, rail, and aviation noise. Three overlapping noise sources drive that ranking:
Logan Airport flight paths. Logan sits just 5 miles from downtown Boston — one of the closest major-city airport pairings in the U.S. — with six runways pointing directly at East Boston, Winthrop, Revere, Chelsea, and South Boston. Massport's own noise maps put parts of East Boston at 65+ dB, and the agency has spent over $170 million soundproofing roughly 11,000 homes and 36 schools around the flight paths — an acknowledgment that standard construction isn't enough.
The MBTA Green, Red, and Orange Lines. Surface rail sections rattle through Cambridge, Allston, Jamaica Plain, and the South End. Low-frequency train rumble travels directly through glass that's meant to keep out wind.
I-90, I-93, and street-level traffic. Boston's density puts housing hard against both interstates. Storrow Drive, Commonwealth Avenue, and Mass Ave are effectively 24-hour noise corridors for brownstones and triple-deckers that face them.
How CitiQuiet Window Soundproofing Works
SoundProofUSA is the exclusive authorized CitiQuiet soundproof windows dealer in the United States. Soundproofing CitiQuiet inserts are custom-fabricated to your exact window dimensions and mount inside your existing frame — no replacement, no permits, no mess. The system combines:
- Laminated acoustic glass that absorbs sound energy rather than transmitting it
- An air gap between the insert and your existing window that decouples vibration
- Compression perimeter seals that block the air leaks where most noise actually enters
The result is a measurable STC improvement of 10–15 points and up to 95% noise reduction — more than most full window replacement options deliver, at a fraction of the cost and disruption.
Real Examples by Neighborhood

| Back Bay Brownstone | Storrow Drive traffic, weekend crowd noise | Homeowner maintained historic windows; sleeping through the night. |
| Cambridge Triple-Decker | MBTA Green Line surface section | Low-frequency rail rumble eliminated that double-pane couldn't touch. |
