Airborne and Impact Sound Insulation Measurements
made easy
The Exel Building Acoustics Kit consists of the
instruments and software required for professional airborne, impact
and facade sound insulation measurements. With the latest
enhancements, Building Acoustic consultants can utilize a
comprehensive package for remote-controlled measurement. For
simultaneous measurement in the source and receiving rooms, Wi-Fi
communication takes over from the more traditional cable connection
methods.
The XL2 Acoustic Analyzer in combination with the 'Sound
Insulation Reporter' PC-software offers a professional and intuitive
building acoustics measurement solution. The sound reduction index, a measure of the sound
insulation provided by a partition between two rooms, is determined
precisely and in accordance with the relevant ISO or ASTM standards.
In order to determine the sound reduction index, an excitation
signal is generated (from an airborne or impact sound source) on one
side of the partition and the reduction in sound across the
partition is determined by measuring the sound levels with an XL2 in
both the source and receiving rooms.
The Basic Configuration For consultants
infrequently called on to carry out sound insulation measurements,
one XL2 with its associated microphone would be a sufficient system
configuration for the assessment. The process is to firstly measure
the average level in the source room then measure the average level
in the receiving room. Finally, connect the XL2 to your PC via the
USB interface and manually load the results into the Sound
Insulation Reporter PC-software for immediate reporting.
