Understanding Sound Transmission

Soundproofing for Floors”


Sound travels in the form of sound waves or vibrations, which travel through sources such as air, water and all kinds of solids. Hence, sound vibrations can easily travel through your floors. There are three different ways of sound transmission – airborne, flanking and impact. 

Airborne, as the name suggests is when sounds travel through air. Impact noise is when there is an impact of two substances colliding – such as footsteps, doors banging, moving furniture, etc. 

While flanking noise is all the sound that travels around your soundproofing materials, bypassing them through any gaps and cracks. It is important that we understand the difference between these to understand which of these are causing issues for us and which need to be worked upon. 

Once you are able to identify the kind of noise, the problem areas, it becomes extremely easy to choose the right materials for the perfect soundproofing solutions.
