If the rumble from SR 37 makes you turn up the TV or lose sleep, you are not alone. Living near a busy corridor in Bedford brings convenience along with traffic noise, especially for homes closest to the roadway. The good news is you can cut that noise with practical steps that fit different budgets. In this guide, you will learn what really works, what to expect, and how to plan upgrades that make your home feel calmer. Let’s dive in.
Why SR 37 noise feels loud in Bedford
SR 37 is a primary route with steady traffic and trucks, so nearby homes can hear more road noise during rush hours and at night. Houses within the first few hundred feet of the roadway, or with a clear line of sight to traffic, often notice it most. Breaking line of sight and improving your home’s exterior shell are the most effective ways to reduce what you hear. The city enforces “unreasonable noise” from sources like loud exhausts or amplified sound, but roadway noise is handled through transportation planning, not tickets or a single dB limit in the code. If you have non‑road noise concerns, review Bedford’s ordinance and contact the police department for guidance.

How highway sound works
Highway noise is usually measured in A‑weighted decibels (dBA) and often reported as Leq, the average over a period. A 3 dB change is the smallest difference most people notice, while about 10 dB sounds roughly twice as loud. Sound from a roadway tends to drop a few decibels each time you double the distance, but close to the road that drop can feel small. The practical takeaway is simple: you get the best results by combining distance or barriers outside with airtight, higher‑performance windows and doors inside.

Quick fixes that punch above their weight
Start with sealing, because small gaps undo bigger investments.
- Seal window and door perimeters with quality caulk; add weatherstripping where you see daylight.
- Install door sweeps and gasket kits on exterior doors. A tight door can stop a surprising amount of noise.
- Seal wall penetrations and electrical boxes on exterior walls.
- Add heavy curtains, rugs, and bookshelves to reduce echo. Interior absorption does not block outside noise, but it can make rooms feel calmer.
Windows that make a difference
Start with window inserts
Interior acoustic window inserts sit inside your existing frame and create a wider air gap, which reduces sound transmission. They are lower cost and less disruptive than full replacement, and they preserve original sashes. Typical pricing ranges roughly from $25 to $40 per square foot, or about $250 to $600 per average window, depending on size and product.

When to replace windows
If inserts are not enough or your windows are failing, consider replacement units with laminated or asymmetric glass and well‑sealed frames. National averages for full replacement vary widely by size and type, often about $300 to $2,100 per window, with premium acoustic units higher.

Set expectations with STC and OITC
Sound Transmission Class (STC) is a lab rating that helps compare how well windows, walls, and doors reduce airborne sound, especially speech. Outdoor‑Indoor Transmission Class (OITC) is more sensitive to the lower frequencies you hear from trucks. A change of about 5 STC points is clearly audible. Ask for laminated or asymmetric glazing and proper sealing to boost real‑world performance.

Doors and walls that stop leaks
A hollow‑core exterior door is a weak link. A solid‑core or acoustically rated door with perimeter gaskets and an automatic door bottom can make a clear difference for rooms facing SR 37. For persistent problems, adding mass and damping inside walls helps. A common upgrade is a second layer of drywall with a viscoelastic damping compound between layers. Installed correctly, it can push assemblies into much higher performance ranges.

Attic, ventilation, and comfort
Air sealing and insulation in the attic reduce both energy loss and sound paths into living spaces. With Bedford’s seasonal swings, good insulation also makes it easier to keep windows closed on loud nights. If you tighten the home, ensure you have balanced mechanical ventilation so indoor air quality stays healthy.

Outdoor measures and DOT projects
Well‑designed barriers that block line of sight between the road and your yard can reduce outdoor sound by about 5 to 10 dB, and sometimes more in the right geometry. Barriers work best for homes within roughly 200 feet and must be continuous and tall enough to minimize sound wrapping around the ends. Landscaping improves screening and perception, but vegetation alone rarely delivers large dB reductions unless it is very deep and dense. On public projects, INDOT evaluates noise abatement feasibility and reasonableness during planning. Engage early if you believe your area should be studied.

Costs and incentives at a glance
- Window inserts: roughly $250 to $600 per window depending on size and product. See the insert cost guide above for context.
- Replacement windows: often $300 to $2,100 per window, with acoustic options higher.
- Wall upgrades: adding drywall with damping is a moderate material cost plus labor; scope and access drive totals.
- Possible federal credit: qualifying Energy Star exterior windows may be eligible for the Energy Efficient Home Improvement Credit. Keep manufacturer certifications and talk with a tax pro.

A simple step‑by‑step plan
- Walk the house. Note which rooms face SR 37 and when noise is worst.
- Seal the easy leaks. Caulk gaps, add weatherstripping, and install door sweeps.
- Treat the priority rooms first. Add acoustic window inserts to bedrooms and your home office.
- Reassess. If noise is still disruptive, price laminated or asymmetric replacement windows for the noisiest openings and consider attic air sealing and insulation.
- For stubborn low‑frequency rumble, talk with an acoustical specialist about wall upgrades and with neighbors about any upcoming INDOT project meetings.
- Check programs and credits. Review weatherization eligibility and gather documentation for possible federal credits.

FAQs
How can I reduce SR 37 noise in a Bedford home without major remodeling?
- Start with air sealing, door sweeps, and acoustic window inserts in the loudest rooms; these low‑disruption steps often deliver the best first gains for the cost.
Do trees or shrubs along my yard cut highway noise meaningfully?
- Vegetation helps with visual screening and perception, but large dB reductions usually require a solid barrier that blocks line of sight between your yard and the road.
What window options work best against traffic noise from trucks?
- Laminated or asymmetric glazing with tight seals performs better than standard double‑pane alone, and interior acoustic inserts can be a strong alternative if you want to keep existing windows.
Can public projects add a noise wall for our street along SR 37?
- INDOT evaluates barriers during project planning using feasibility and reasonableness criteria; engaging early in public meetings is the best way to request a noise study.
Are there rebates or credits for sound‑reducing windows?
- Qualifying Energy Star exterior windows may be eligible for a federal Energy Efficient Home Improvement Credit; confirm details in current IRS instructions and with a tax professional.
