Nor277 Tapping Machine

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 legally defensible impact sound insulation ratings such as L'nT,w and Ln,w for building code compliance across the GCC region and internationally. Designed for both laboratory and field use, the Nor277 features a built-in self-calibrating test function that verifies hammer force and timing accuracy before each measurement session. This ensures consistent, traceable results whether testing floors in a controlled ISO 10140 test facility or conducting field surveys on Vision 2030 residential developments across Saudi Arabia and the UAE. The remote start capability allows operators to position the tapping machine on the test floor and initiate operation from the receiving room, streamlining the measurement workflow. The Nor277 operates on battery or mains power, making it versatile for sites without reliable electrical supply. Its robust yet portable 10 kg design withstands the demands of daily field use on active construction sites. Low background noise operation ensures that the machine's own mechanical noise does not contaminate measurement results, a critical requirement for accurate low-frequency impact sound assessments in lightweight floor constructions increasingly used in modern GCC high-rise developments.
