FLEXIBLE WALLS FOR ENVIRONMENTS WITH HIGH REQUIREMENTS
For rooms with high demands on sound insulation Winab can offer movable walls and folding walls that are tested and classified according to domestic standards and international requirements.
The walls are tested under laboratory conditions and have gained an approved laboratory value denoted Rw. The laboratory Rw value is different from the field Rw value. The field value is measured in the actual environment where construction is built and usually lands about 3-6 dB lower than the Rw value. Flank transmission often occurs with sound slipping over, under and next to the wall. This may in some instances reduce the field value even more.
The walls have been sound tested by the Swedish National Testing and Research Institute and sound classed with a noise reduction equivalent to Rw 41-53 dB lab value. The field value will be slightly lower.
The perception of sound is largely subjective and subjectively linked to the individual at a particular time. Here follow some guidelines for how the varying degrees of sound insulation can be perceived in different situations.
|R’w 48-51 dB||Offers conversational privacy. Screams and loud sound activities can however be heard. A soundproofing level which, however, offers acceptable conditions in environments where the confidentiality requirements are not complete but the privacy requirements are clear.|
|R’w 44-47 dB||Provides some conversational privacy. Single words in loud conversation can be heard but not really perceived. A sound insulation level that can be considered as a relatively high standard for instance in office spaces where work areas must be separated from the conference room.|
|R’w 40-43 dB||Loud conversations can be perceived yet are difficult to distinguish in detail. A sound insulation level that can be regarded as being the minimum standard where there are requirements regarding sound insulation and privacy.|
|R’w 32-39 dB||Normal conversation can be heard at lower sound insulation levels. At the upper levels single words can be heard at normal conversational levels but can be difficult to perceive. A low insulation standard which can be acceptable in cases where there are low requirements regarding sound insulation.|
ACOUSTIC WALLS CAN IMPROVE THE SOUND IN THE ROOM EVEN MORE
The acoustics in the room are caused by sound waves bouncing around between the walls, floor and ceiling. When you can get the sound to stop bouncing around the room the sound in the room is perceived as being more pleasant.
