Total sound insulation is the ability of a room (partitions, ceiling, floor and all connections) to prevent sound from travelling through the air and through building elements.
The total sound insulation of adjacent spaces is expressed by DnT,w, R’w or DnT,A values. The higher the value (in dB), the better the performance. Mass, air-tightness and absorbing ability are the primary properties that determine the ability of a material to insulate against sound. Some regulators require a minimum of 35-45 dB between offices.
|EXPERIENCE BY THE USER||RECOMMENDED ROCKFON SOLUTIONS|
|30 dB (A)||A conversation in the adjacent room can be clearly heard and understood||Sonar dB 35 and dB 40|
|40 dB (A)||A conversation in the adjacent room is experienced vaguely||Sonar dB 44|
|50 dB (A)||The sound in the adjacent room cannot be heard||Sonar dB 44 + Sound barrier/light cap/absorbing material|
Impact sound insulation between floors is the ability of a construction to insulate from impact noises such as footsteps. It is characterised by the impact sound pressure level L’nT,w in dB. The lower the value, the better the impact sound insulation. Regulators usually allow a maximum L’nT,w of 60 dB in classrooms and offices.
