Anechoic Chambers

Unger Technologies anechoic test chambers, hemi-anechoic, and quiet rooms are manufactured with modular, metal acoustical panels. This modular
approach allows us the ability to construct acoustical rooms and chambers of various sizes, shapes and
applications. Each component is pre-engineered and can be interchangeable. Our systems can include a selection of acoustical doors, windows, ventilation
systems, etc., to handle many different job requirements. Totally integrated systems and designs include requirements such as isolated floors, light and power connections, ventilation, temperature and humidity control, instrumentation sleeves, control supports, working floors, and single and
double sound doors. Unger can also supply, if necessary, a floating floor system to match the acoustical isolation properties of the chamber walls. Host site conditions and the desired level of acoustical performance determine the floor design parameters.

Anechoic Chambers provide an essentially free-field environment for the measurement of spherically radiated sound waves emanating from a sound source. Anechoic Chambers are echo-free enclosures with a sound energy absorption level of 99% to 100%, or a reflected sound pressure level of 10% or less. The frequency at which the energy absorption drops below 99%, or the pressure reflection exceeds 10%, is known as the low-frequency cut-off. Sound absorption is obtained by lining the walls, ceilings, and floor with wedges or other sound absorbing elements, depending on performance level required and cut-off desired.
