Sound Transmission Through Concrete Walls

When it comes to concrete and soundproofing you should always focus on coating the walls with a layer of noise reduction materials first. First it effectively blocks airborne sound transmission over a wide range of frequencies. So how does sound travel through concrete.

Many building codes require minimum sound transmission loss values expressed as sound transmission class stc of 45 to 50.

Sound transmission through concrete walls.

And lastly the object absorbs part of the sound wave. Most of the sound energy isn t traveling through the wall which is why it provides such an effective noise barrier. Concrete masonry offers excellent noise control in two ways. Our quiet batt insulation provides a layer of friction between your walls that guarantees minimized sound transmission into and out of your room.

152 and 203 mm thick cast concrete walls. Second concrete masonry effectively absorbs noise thereby diminishing noise intensity. This is especially true when speaking about the adjoining walls between hotel rooms apartments and condo units. Reducing sound transmission through walls walls rank among the top three structures commonly cited as sources of sound transmission.

203 mm thick concrete masonry walls and on 6 and 8 in. Concrete masonry walls are often used for their ability to isolate and dissipate noise. These walls are often referred to as the party walls. Tests of sound transmission loss were made on 8 in.

Concrete walls are designed to reflect noise towards the source and absorb some of the energy from the sound wave. When absorption occurs the sound wave is converted into heat energy. Secondly a certain amount of the sound wave is transmitted. Sound attenuation in building elements like massive concrete walls or floors sponsored links the sound transmission through a massive wall or floor depends primarily on the mass of the construction.
