I can hear my kids running around upstairs and I'm wondering how to reduce the impact noise?

Impact noise from footsteps above requires different solutions than airborne sound — you need to address the vibrations transferring through the floor structure, not just add sound absorption.

Impact noise occurs when footsteps, dropped objects, or furniture movement create vibrations that travel directly through the floor joists and into the ceiling below. Unlike airborne sound (voices, TV), impact noise transmits as structural vibration, which is why simply adding insulation to the ceiling cavity provides minimal improvement. The most effective solutions address the impact at its source — the floor above — or decouple the ceiling below from the structure.

Floor-Side Solutions (Most Effective)

The best approach is treating the floor above where the impact occurs. Carpet with quality underpad is the most economical solution, reducing impact noise by 15-25 dB — that's the difference between clearly hearing every footstep and barely noticing them. Choose carpet with thick, dense underpad rather than thin foam. Engineered underlayments like cork, rubber, or specialized acoustic products (such as QuietWalk or similar) can be installed under hardwood, laminate, or tile flooring. These typically cost $2-4 per square foot installed and can reduce impact noise by 10-20 dB.

For more serious impact control, floating floor systems completely decouple the finished floor from the subfloor using resilient pads or sleeper systems. This premium solution costs $8-15 per square foot but can achieve 20-30 dB impact noise reduction.

Ceiling-Side Solutions

If treating the floor above isn't possible, ceiling modifications can help. Resilient channel with double drywall decouples the ceiling from the joists, reducing both airborne and impact noise transmission. This involves installing RC-1 resilient channel perpendicular to the joists, then hanging two layers of 5/8-inch drywall with Green Glue damping compound between them. Expect to pay $12-18 per square foot installed for this approach.

Sound isolation clips with hat channel provide superior decoupling compared to resilient channel alone, achieving better impact noise reduction but at higher cost — typically $15-22 per square foot installed.

Ottawa Climate Considerations

In Ottawa's climate, any ceiling modifications must maintain proper vapour barrier placement on the warm side of the insulation. Impact noise solutions that involve ceiling work during winter months may require temporary heating if working in unheated spaces, as Green Glue and adhesives need temperatures above 10°C to cure properly.

Practical Tips

Start with the simplest solutions first — area rugs with thick pads can provide surprising improvement for high-traffic areas upstairs. Address squeaky floors, as these amplify impact noise. Consider the timing of the noise — if it's mainly during specific activities, behavioral solutions (slippers, designated play areas) combined with modest acoustic improvements may be sufficient.

Avoid common mistakes like adding only insulation to the ceiling cavity (minimal impact on structural vibration) or using acoustic foam panels (designed for echo control, not impact noise blocking).

For significant impact noise problems affecting your family's comfort and sleep, consulting with an experienced soundproofing contractor can help you choose the most cost-effective approach for your specific floor-ceiling assembly and budget.
