Soundproofing values

Soundproofing values

The soundproofing values (Rw,R) that can be achieved using the HAWA Suono fitting system in buildings depends on the type of door that is used (door leaf value Rw) and the type of floor seal.

  • A door leaf value of Rw 45 dB makes soundproofing of up to Rw,P 39 dB possible, depending on the configuration.
  • A door leaf value of Rw 40 dB makes soundproofing of up to Rw,P 34 dB possible, depending on the configuration.

Worth knowing

Worth knowing

Rw,P Laboratory value (must be at least 5 dB higher than the soundproofing value required for the building).
Rw,R The mathematically expected soundproofing value for the building (Rw,P - 5 dB = Rw,R).
Rw Tested door leaf value without influence of adjacent parts of the building.
Example If a soundproofing value of Rw,R = 27 dB (SSK1) is to be achieved on the building, a product with at least Rw,P = 32 dB must be used.
SPC 1 Soundproofing class 1 Rw,R ≥ 27 dB → Rw,P ≥ 32 dB
SPC 2 Soundproofing class 2 Rw,R ≥ 32 dB → Rw,P ≥ 37 dB

  • «The soundproofing of sliding doors, which is usually low, has unfortunately limited the use thereof considerably to date - we are therefore delighted that a solution is now available».
    Gordian Bayer, partner and managing director at erp Architekten, Baden
  • «An increase of ten decibels to the sound pressure level is perceived by human hearing as about twice the volume».
    Dr. Joachim Hessinger, qualified physicist at ift Rosenheim
  • «HAWA Suono – a wonderful pioneering achievement which makes soundproofing sliding doors possible: Finally, sliding is not just attractive but also tight! Guaranteed as a certified product by the door specialist».
    Heinz Haab, CEO Hawa Sliding Solutions
  • «HAWA Suono with its 3-dimensional sliding movement opens up completely new perspectives for the use of sliding doors».
