Nor277 Tapping Machine
Standard tapping machine for impact noise measurements in building acoustics testing.
Overview
The Nor277 Tapping Machine is a precision-engineered standard impact sound source for measuring footfall noise transmission in buildings. Fully compliant with ISO 10140-5, ISO 16283-2, ASTM E492, and ASTM E1007, the Nor277 generates a standardized sequence of mechanical impacts at exactly 10 Hz using five 500 g hammers dropped from a controlled 40 mm height. This repeatable excitation enables lega…

Frequently Asked Questions
- Does the Nor277 meet ISO 10140-5 requirements?
Yes, the Nor277 is designed to meet all requirements of ISO 10140-5 for standard tapping machines, including precise hammer mass, drop height, and impact rate specifications. - Can the tapping machine be started remotely?
Yes, the Nor277 supports remote start for convenient operation during building acoustics measurements. This allows the operator to remain in the receiving room while initiating the tapping machine on the test floor above. - What is the self-calibrating test?
The built-in self-calibrating test verifies the impact force and timing accuracy of all five hammers to ensure measurement reliability and compliance with ISO 10140-5 specifications.
