Building Acoustics

Overview

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.
