Description

Wall, Ceiling, Doors and Floors

Multi-Channel Measurement System + SAMURAI Software + SAMBA Software option by SINUS Messtechnik GmbH + Microphones

 

Laboratory or field in-situ testing of sound transmission through walls, doors, ceilings and floors, as well as floor impact isolation, may be conducted in accordance with a range of international standards using a multi-channel measurement system plus SAMURAI software, including the Building Acoustics (SAMBA) Software Option. The multi-channel measurement system may include the SoundBook or NoisePAD, or the Expander/Apollo/Apollo Lite Boxes plus laptop, all by SINUS Messtechnik GmbH.

Field of Application:

The transmission of sound through various constructions or construction details are important properties to quantify when specifying and testing the acoustical properties of rooms, dividing walls, ceilings and floors; various construction elements, such as windows and doors, as well as building materials.

The SAMURAI Building Acoustics (SAMBA) Software Option is used to measure sound transmission between adjacent spaces from which airborne and impact sound insulation indices and ratings may be determined.

Description:

Apart from reverberation time measurements (which are already included in the basic SAMURAI acoustic software bundle), the Building Acoustics (SAMBA) Software Option enables the source, receiving and background noise spectra to be measured and the data organized into a format suitable for analysis according to the standard selected. The measurements and reporting functions are integrated in the software into a cohesive and clear user interface. The excitation of the rooms can be performed with noise, impulse or sine sweep signals played through a suitable amplifier and speaker system.
