Examples of areas where the requirements for sound insulation is between 43 og 54 dB

Sound insulation between meeting rooms must have a value of ≥ 48 dB. Between areas in which confidentiality is requested and other areas there will be requirements for a higher sound insulation.


In daycare buildings the requirements for sound insulation are ≥ 48 dB between living rooms for quiet and/or noisy activities and other rooms.

dB:  Air sound insulation is measured in decibels = dB. The scale is logarithmic, so 50 dB + 50 dB is not 100 dB, but 53 dB. Thus, halving or doubling the effect of the sound corresponds to 3 dB. The human ear recognises sound as halved or doubled each time the level is changed by approximately 8-10 dB. (source Alpha Akustik). 


RwA distinction is made between air insulation measured in the laboratory Rw and

wMeasurements are carried out in the current construction site, where the field value is w.


As a rule, the field value is 2-3 dB below the value measured in the laboratory.


Rw+C: Measurement for sound insulation against talking, TV, playing children etc.


Rw+Ctr: Measurement for sound insulation against rhythmic music with powerful bass or city traffic noise.
