Examples of areas where the requirements for sound insulation is not higher than 36 dB

There are usually modest requirements for sound insulation in open areas where partitions don’t close off the room completely but mainly act as shields to separate some areas of the room.


Here you only have a requirement of ≥ 20 dB.


In daycare buildings the requirements for sound insulation are ≥ 30 dB between living rooms with doors as well as between the living room and other rooms with connecting doors (total sound insulation for wall with door).

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.
