SONIC.MLNR the Sonic Picker!

The acoustic hammer is a measuring device for stimulating/exciting the resonance frequencies of components and structures. The resonant frequencies are picked up by a microphone via airborne sound. All measurement data are saved and documented. The acoustic hammer can be used for comparative non-destructive testing. The measurement results are used to check the quality of components with regard to microstructure, strength, connection quality, cracks, etc.

For use on metal, wood, plastic, concrete, stone, hybrid material and others.

Application fields:

• Material structure strength
• Structure health monitoring
• Anchorage fasting
• Civil constructions

FUNCTION:

• Stimulating
• Measuring
• Testing
• Documentation

OPERATING PRINCIPLE

The acoustic resonance analysis uses the physical effect that a body (component) after a suitable vibration excitation oscillates in its typical natural frequencies (more specifically “vibrational footprint”). The natural frequencies are determined by geometry and material properties. Acoustic material testing uses exactly this effect to detect changes in the component. The acoustic material test is a comparative method. Oscillations and vibrations can be recorded using airborne or structure-borne noise.
