Reference Magnet
Reference magnets generate a homogeneous magnetic field in an air gap. They are mainly used to calibrate hall probes for their full scale value of output for the magnetic field strength H or the magnetic flux density B they measure. For example Gaussmeters can be calibrated by using reference magnets.

Acoustic Emission Sensors
Acoustic wave (acoustic emission) sensors are the ceramic piezoelectric transducers converting the mechanical elastic acoustic waves generated in the material (e.g. elastic waves occur when a material cracks, wears, deforms, or corrodes) to electrical signals. The electrical signals are then amplified and filtered by a preamplifier and then transmitted to a special acoustic emission acquisition instrument for further data processing and analysis.

Building Acoustics
Measurements to evaluate and improve Building Acoustics are typically made to analyze and design noise control from room to room, or from outside to inside. Noise sources such as music systems, televisions, appliances, traffic, aircraft, and manufacturing are all around us. The field of Building Acoustics evaluates and designs the materials and methods to insulate and isolate us all from these sound sources when we are at work, rest, or enjoying leisure time. The resulting data is useful for evaluating compliance with building codes and for proposing countermeasures for areas of concern. These measurements often involve creating and measuring an artificial sound source, and then measuring the resulting noise in receiver locations.
