Soundproofing for Ceilings

Soundproofing for Ceilings, what you need to know
In order to solve sound problems it is important to know the exact source of the problem and how the sound propagates. Below you will find a brief explanation of what may cause a sound problem and what soundproofing products you need use to isolate it.

What is airborne noise?
Airborn sound, or noise, is sound that travels through air. This is sound produced by a noise source that causes the actual nuisance. Examples of airborne noise include speech, television/radio, appliances and traffic noise.

What is impact noise?
These are the sounds produced by vibrations in the structure of a building, for example floors, walls or ceilings. Forms of contact noise can be: noise caused by walking, closing doors, playing children (e.g. dropping toys) or resonating machines and appliances such as a washing machine. In that case you experience this as sounds or physical vibration.Impact noise from appliances are often perceived as a humming sound.

What is flanking noise?
A ceiling that extends from one building via a (single-brick) wall to another building radiates flanking noise. In this case, insulating the ceiling alone may not be sufficient, the walls will also need to be soundproofed with, for example, Akoestikon Acoustic Stud system.

What to soundproof and which products to use?
Nuisance from airborne noise from upstairs neighbours is largely due to the direct separation with the neighbours, in this case the ceiling. By soundproofing the ceiling with Akoestikon Acoustic Stud system you can reduce the problem. After the installation of a Akoestikon Stud system, the noise radiated from the ceiling is absorbed by the acoustic filling Akoestiwol and soundproofed by the two plasterboards that are mounted on the resilient Acoustic studs/rails. This approach is also called the "room-in-room" principle, creating a floating room inside an existing room, which is the best approach. The more separation you can create between you and your neighbors by using the Akoestikon Acoustic Studs, the better the result.

In somewhat older buildings with low, wooden ceilings the Akoestikon Studs may be too thick. In that case you fill the hollow spaces between the beams for at least 70% with Akoestikon Insulation Wool and finish this with two layers of plasterboard. Between those two layers you need to add mass, the extra weight adds to the soundproofing, use the mass loaded vinyl Isomat KE FIber to do so.

What can I expect in terms of results?
The behaviour of vibrations and noise is complex, it is difficult to predict what the end result will be. That is why the above mentioned products have been tested and measured in laboratories to give an indication. You will find this information in the downloadable product sheet together with the manual. The result is influenced by the building itself and the construction of the property and the amount of flanking noise that enters your room in other ways.
