What’s the Difference Between Airborne Sound and Impact Sound?

There is more than one type of sound and to properly insulate your property you will need to insulate against both impact sound and airborne sound. Here’s a brief guide to these sound types and how effective insulation can help you control their impact.

Airborne sound can come from a wide variety of sources bot inside and outside your property and as the term suggests the sound will feel as if it is in the air around you. Some typical examples of things that create airborne sound include noise from traffic, music, TV vacuum cleaning to name but a few.

Being exposed to these noises for any length of time can impact on your quality of life depending on the level of noise they generate and for how long.

Impact sound on the other hand is generated when people are walking up stairs, on floors above in apartments, or appliances such as washing machines, drills, hammers and so on. This type of noise can be particularly irritating even if the disturbances are usually short term in domestic environments.

Sometimes noise can fall into both airborne and impact sound categories when sound vibrates from a surfaces.

The key to reducing airborne sound is to eliminate gaps that will allow sound to travel between spaces. Impact noise can be reduced by something as simple as fitting carpets that are significantly better at absorbing impact sound from footsteps than wood floors.
