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.

Basically, there are four ways to achieve noise reduction:
Add a physical sound barrier
Install a vibration damper
Provide sound absorption
Metering the air flow
Only knitted wire mesh functions as all four of these types of noise reducers-economically and as a single-composite material.
Unlike metal baffle plates-which usually involve costly welded constructions and add significant weight-Metex knitted wire mesh noise-suppression solutions are light in weight and economical. Metal baffles can also slow the passage of air-in some cases resulting in reduced equipment operating efficiency due to generation of excessive back pressure. Porous materials such as foamed plastics and synthetic felts are highly susceptible to degradation at elevated temperatures-leading to eventual embrittlement and decomposition.
Knitted metals can be virtually custom tailored to specific needs of a given application. Engineered products can be fabricated from Metex by knitting one or a combination of widely diverse materials, such as all types of stainless steel, aluminum, copper, sophisticated alloys, synthetic polymers, fibers, and yarns.

The mufflers are elements that are inserted in the conduits where a gas flows. Their job is to reduce as much as possible the transmitted of noise.
A muffler must be chosen using the following criteria of selection.
The sound transmission loss must be the major possible one, not only worldwide, but also spectrally.
Depending on the speed of the gas, there will be demanded a few aerodynamic special conditions.
The materials that compose the muffler will come determined by the temperature and the pressure of the gas. The permanence of the set will depend on the quality of the selected material.
The geometry and dimensions of the muffler will come determined in every case for the available space, the wealth and the loss of load. There are situations in which the volume is very limited, for example in case of the leaks of compressed air.
