Sound Level Analyzer Kit helps comply with IEC 61043 standards.
October 14, 2010 -
Comprised of hand-held sound level analyzer, Sound Intensity Software, and Sound Intensity Probe Kit, battery-operated Model 2270-G enables user to make sound intensity measurements complying with IEC 61043 standard. Software uses intensity technique to determine sound power levels and locate noise sources using contour maps. With phase calibration technique, users can make all measurements with 12 mm spacer covering frequency range from 50 Hz to 10 kHz.

Brüel & Kjær launches hand held sound intensity system - 2270-G
DENMARK, Machinery manufacturers required by law to provide precise specifications of products noise levels can reduce the time and effort involved, by using Brüel & Kjær's new hand held sound intensity system: 2270-G.
A combination of strict legislation and customers demanding noise-friendly surroundings has increased pressure for manufacturers producing products - such as washing machines, refrigerators, lawn mowers and electric motor devices - to label the noise output in accordance to national and international standards.
Many machines also contain parts from sub-suppliers, which means in order for manufactures to predict noise output, they must label individual parts to ensure the final product is in accordance with national and international standards.
To simplify this process, Brüel & Kjær has created its 2270-G, a complete sound intensity system comprising of the hand-held sound level analyser (2270), Sound Intensity Software (BZ-7233) and Sound Intensity Probe Kit. This portable, battery operated system allows one person to make sound intensity measurements complying with the IEC 61043 sound intensity standard.
Users simply swap the 2270 meter's microphone for the sound intensity probe to start measuring. The BZ-7233 software transforms the analyser into a powerful measurement tool, using the intensity technique to determine sound power levels and locate noise sources using contour maps. A unique phase calibration technique allows users to make all measurements with a 12mm spacer covering a frequency range from 50 Hz to 10 kHz.
The sound intensity system is part of Brüel & Kjær's 2270 range, which offers many sound and vibration analysis applications. For more information, please visit: www.bksv.com/Type2270G
