To achieve free-field conditions within an acoustic test environment for the measurement of radiated sound power and directivity, the testing area must be free from reverberation, feedback and resonance throughout the audible frequency spectrum. pinta's SONEX Wedges, cut in a variety of sizes and shapes, are effective materials for use in anechoic and hemi-anechoic chambers. The acoustical wedges absorb the kinetic energy created by the sound waves. At the same time, the large surface formed by the wedges increases the total absorptive area to absorb even the long wavelengths of low frequency sound.

Elastomers have two major properties:
- they are practically incompressible;
- when subject to shear, they have a very low modulus which means that show small reactions for high amplitudes
The shear and compression properties of elastomers enable laminated assemblies to be used as conventional bearings:
- immobilization and load bearing capacity in certains directions;
- capacity to move in directions perpendicular to the previous one.
