- Extends the Nor140 instrument into a complete single channel building acoustic analyser.
- Synchronises excitation in the source room with the measurement operation (option 10)
- Makes room averaging of multiple microphone positions for sound level and reverberation time measurements for ISO 140/717 users:
- Calculates the survey and engineering grade airborne sound insulation ratings R’w, D’n,w , and D’nT,w
- Calculates the survey and engineering grade impact sound insulation ratings L’n,w and L’nT,w
- Calculates the correction terms C, Ctr and Ci including the extended frequency versions
- In conjunction with NorBuild, can easily calculate rating per ASTM and other National Standards
- Allows remote use in combination with the Nor1028/3 CtrlBuild software package
- Can be used for cable-free measurements using the Nor520 Bluetoothe Transceiver
- Fulfi ls the requirements of the survey grade ISO 10052 Standard
Option 11 turns your Nor140 into a powerful single channel building acoustic analyser. All the required para-meters for performing both airborne and impact sound insulation are calculated. Using the Nor140 for measuring building acoustic, both airborne and impact noise has never been easier. With the Nor1028 NorBuild sound insulation reporting program, Norsonic offers a powerful and user-friendly building acoustic solution.
Option 11 requires that minimum option 1, 3, 9 and 10 be installed.
