Anechoic Chamber

    An anechoic chamber (an-echoic meaning non-echoing or echo-free) is a room designed to completely absorb reflections of sound. They are also insulated from exterior sources of noise. Anechoic chambers are commonly used in acoustics to conduct experiments in nominally "free field" conditions. All sound energy will be traveling away from the source with almost none reflected back.

                   

Digital 3D Image Correlation System

    The Digital 3D Image Correlation System is an optical measuring device for true full-field, non-contact and three-dimensional measurement of shape, displacements and strains on components and structures.This system is used for determination of three-dimensional material properties in tensile, torsion, bending or combined tests. In addition, deformation and strain analysis can be applied to fatigue tests, fracture mechanics, FEA validation and much more.
