Flanking sound transmission of cavity and raised floors
Acoustics
| Measurement | Normalized flanking impact sound level, normalized flanking level difference |
| Standard | DIN EN ISO 10848-2 |
| Measurement object | Cavity and raised floors, floor systems with air terminals, bulkheads (absorbent, boards) |
Technical data
| Floor area (2 rooms) | 21 m² and 24 m² |
| Room volume (2 rooms) | 66 m³ and 76 m³ |
| Entrance doors (H × W) | 1.990 × 0.835 and 2.02 m × 1.95 m |
| Height of the floor system | Variable |
Special feature
| Max. sound reduction (related to the size of test sample) | R'max,w = 89 dB |
More information
- The height of the floor system can be varied but will influence the room volume.
- The separating wall above the floor system is made of a multi-layer panel construction with high sound insulation.
