Residential acoustics · Germany

Calmer rooms through sound-aware building.

A reference on how German households reduce noise indoors: airborne and impact sound through walls, floors and windows, the materials used for insulation, and the treatment that shapes how a room sounds.

Two problems, two methods

Sound insulation and room acoustics are not the same thing.

Insulation keeps sound from passing between spaces. Acoustic treatment changes how sound behaves inside one room. Mixing the two leads to disappointment — foam on a wall will not stop a neighbour's television.

Airborne sound

Rw

Speech, music and television travelling through a building element. Reduced with mass, decoupling and sealed gaps.

Impact sound

L'nT,w

Footsteps and dropped objects transmitted through floors. Reduced with resilient layers and floating floors.

Reverberation

T (seconds)

How long sound lingers in a room. Shortened with absorptive surfaces rather than added mass.

Topics

Where most home noise is won or lost.

Soundproofing layers being installed on a ceiling

Walls & ceilings

Decoupled stud walls, resilient channels and dense fillings reduce sound passing between flats and rooms in German apartment buildings.

Windows & glazing

Glazing thickness, asymmetric panes and a tight seal matter more than the frame material when reducing street and traffic noise.

Room acoustics

Absorbers and diffusers shorten reverberation and tame echo in living rooms, home offices and small studios.

Materials

Common materials, and what each is actually for.

The same product is often sold for opposite purposes. The table separates materials that block sound from materials that absorb it.
