Summary
The Dynamic Mechanical Metrology Project develops methods to provide accuracy in, and provides calibration services for, acoustic, vibration, acceleration, and force measurements.
Description
The Dynamic Mechanical Metrology Project develops primary standards and primary measurement methods for sound, vibration and force at the highest accuracy levels, and uses these to disseminate traceability in measurements of these quantities to industry and society.
