Examples of areas where the requirements for sound insulation is between 37 - 42 dB
Sound insulation between offices must have a value of ≥ 40 dB. Between rooms 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 ≥ 40 dB between living rooms for quiet and/or noisy activities and other rooms with connecting doors (total sound insulation for wall with door etc.).

HOW TO MEASURE SOUND REDUCTION
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).
Rw: A distinction is made between air insulation measured in the laboratory Rw and
R´w: Measurements are carried out in the current construction site, where the field value is R´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.
