Bettering Ground Audio Insulation Overall performance9106019

As described in the title, two crucial areas require to be seemed at when strengthening a flooring building: the airborne facet (television noise, audio, speech etc.) is typically dealt with by implementing ceiling treatment options and mass to the technique and the influence (footfall etc.) functionality is enhanced by the utilised of resilience and isolation of layers.

Let's search at how to deal with airborne audio insulation in the 1st occasion and then element the actions to boost the absorption of affect sound (although, as you will see, there is an overlap in between the two matters).

Airborne noise soundproofing

In existing dwellings (using the typical case in point of a property transformed into two flats, floor and first ground), the separating ground design normally consists, [http://k-flex.pl/produkty2/akustyka izolacja akustyczna] of the following levels, from best to bottom:

o	Existing floorboards

o	Timber joists

o	Plasterboard ceiling directly fixed to the joists

As you can possibly picture, this minimum development is not satisfactory to individual two dwellings, currently being an internal partition initially. This program would normally obtain a audio insulation functionality of 35dB Dntw   Ctr, way under the 43dB minimum prerequisite (see seem testing discussed for far more specifics).

So, what treatment options are essential to attain ample airborne overall performance?

Numerous simple and not extremely onerous additions ought to be made to drastically improve the soundproofing of this normal flooring.

1st and foremost, any particles gathered in between the joists should be eliminated. For 150mm (six inch) or thicker joists, we would suggest the insertion of medium to high density (all around 40kg/m3) mineral wool in between the joists. This will aid in absorbing medium to large frequencies, converting the seem strength into heat.
