Sound Intensity Measurement Device,
Type 2270-G
Application
The portable, hand-held and battery operated Sound Intensity Measurement Device Type 2270-G is designed to
make intensity measurements for noise source location and sound power calculation.
Description
The sound intensity measurement device consists of the hand-held Analyzer Type 2270 with its accessories and
software packages and the Sound Intensity Probe Kit Type 3654.
The device comes with a weatherproof carrying case housing the analyzer, a probe with a windscreen, an
extension stem with a handle, an intensity adaptor for the Sound Calibrator Type 4231, a tape measure and
earphones. The case can also house optional accessories such as a sound calibrator, a sound intensity
calibrator and spare batteries.
The system provides on-the-spot analyses of sound intensity spectra, which can be exported via utility software
to spreadsheets for sound power calculation.
The hand-held Analyzer Type 2270 can also be completed by a vibration measurement kit.
Advantages
The powerful combination of the hand-held Analyzer Type 2270, the Sound Intensity Software BZ-7233 and the
Sound Intensity Probe Kit Type 3654 makes it possible to carry out a complete sound intensity measurement
from beginning to end.
Automatic measurement guidance and aural feedback during the measurements allow the person carrying out
the measurements to concentrate on making a smooth scan of the area under investigation.
Most of the functionality of the analyzer is generated by the software packages that are loaded into the
equipment. So the performance and the number of features can be increased afterwards if necessary.
