| Field of Application: The field of building acoustics deals amongst other things with the acoustical properties of rooms, dividing walls, structural elements and building materials. The determination of airborne and impact sound insulation is of particular importance. | Description: The SAMURAI option: BUILDING ACOUSTICS (SAMBA) allows the convenient performance of building acoustics measurements according to the standards listed below. Apart from reverberation time measurements (already included in the basic scope of SAMURAI), this option allows the source, receiving and background noise spectra to be determined. The organization of the rooms and transmission paths together with measurement, analysis and report functions are integrated into a cohesive and clear user interface. The excitation can be performed with noise, impulse or sine sweep signals. Technical Data| Standards implemented | ISO 140-3,4,5,6,7,8; ISO 717, ISO 354; ISO 3382 and ASTM standards | | Measurement range | 50 Hz to 5 kHz | | Features | - Clear navigation including status display
- Management of source/receiving rooms and transmission paths
- Management of additional information such as manufacturer, operator, company, address, description, building structure volumes, areas etc.
- Selectable frequency ranges (100 ... 3150 Hz or 50 ... 5000 Hz)
- Measurement of reverberation time spectra EDT, RT15, RT20, RT30; automatic or manual fitting of linear approximations to level decay curves, backward integration selectable
