Who this guide is for
- Homeowners bothered by footfall from above
- People in flats or homes with rooms over rooms
- Anyone planning floors with noise in mind
- Owners wanting to brief a soundproofing specialist
Why impact noise is different
Airborne noise travels through the air; impact noise travels through the structure as vibration. This distinction matters because measures that help with airborne sound do not necessarily address impact noise, and vice versa.
Recognising which kind of noise you have is the first step to the right approach.
- Impact noise travels through the structure
- It differs from airborne sound
- Airborne measures may not address it
Common sources of footfall noise
Footsteps, dragged furniture, and dropped objects on a floor above are typical sources. Because the floor and structure carry the vibration, the noise can be heard well away from its source.
Understanding the source helps a specialist target the path the sound takes.
- Footsteps and movement above
- Furniture being moved
- Dropped or knocked objects
Principles for reducing it
Reducing impact noise generally involves interrupting the vibration path, often through layers that absorb or isolate, applied as part of a considered approach. These are specialist decisions because the structure determines what works.
There is no single trick; the right combination depends on the building.
When to involve a specialist
If footfall noise seriously affects daily life, or you are planning floors where it matters, involve a soundproofing specialist early. They can assess the structure and plan an approach suited to it, rather than you guessing.
Route any construction work to qualified professionals, who can also account for structural considerations.
- Bring in a specialist for serious or planned cases
- Let them assess the structure
- Route construction work to professionals
Impact noise planning checklist
- 1Identify whether the noise is impact or airborne
- 2Note the sources of footfall noise
- 3Recognise impact noise travels through structure
- 4Understand airborne measures may not help
- 5Consider the floor and structure involved
- 6Plan an approach with a specialist for serious cases
- 7Let a specialist assess the structure
- 8Route construction work to qualified professionals
Common mistakes to avoid
- Treating impact noise like airborne noise
- Applying airborne fixes and expecting impact results
- Ignoring the structure that carries the vibration
- Expecting a single product to solve footfall noise
- Assuming what worked elsewhere will work here
- Attempting specialist construction without professionals
When to involve a professional
- Impact-noise reduction is specialist work for qualified professionals.
- How impact noise behaves depends on the structure; approaches are not universal.
- Any work affecting structure or floors should be confirmed with professionals; requirements vary by location.
- Costs and timelines vary by approach and building.
Frequently asked questions
Questions readers ask about this topic
What is impact noise?
Noise from footsteps, dragged furniture, or dropped objects that travels through the building as vibration, structure-borne sound, rather than through the air. This is why it can be persistent and why it needs a different approach from airborne noise.
How is it different from airborne noise?
Airborne noise travels through the air, like voices and music, while impact noise travels through the structure. Measures that help with one do not necessarily address the other, so identifying which kind you have is the first step to the right approach.
Can I reduce footfall noise myself?
Reducing impact noise is specialist work, because the right approach depends on the structure that carries the vibration. There is no single trick, so for serious or planned cases a soundproofing specialist should assess and plan rather than guesswork.
When should I call a specialist?
Early, if footfall noise seriously affects daily life or you are planning floors where it matters. A specialist can assess the structure and plan an approach suited to it, and any construction work should be routed to qualified professionals.
