Eckoustic Functional Panels are high performance, sound-absorbing, fire resistant panels which can be spot located on walls or ceilings to achieve effective noise control.EFPs are independent units that can be put into place without disturbing existing utilities. EFPs provide multi-functional and adaptive acoustic control and do so at considerably less cost than conventional continuous ceiling or wall treatment.

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.

Engineered Acoustical Treatment Combining Functionality and Sleek Aesthetics Eckel Flat Functional Panels (FFP) are engineered to provide maximum sound control. They offer a simple and aesthetically pleasing method of efficiently reducing reverberation levels and background noise in commercial, office, retail, and institutional environments. Due to the FFPs exceptional sound absorption properties and special design features, only a percentage of a rooms wall and ceiling surfaces need effective noise treatment. FFPs operate as an adaptive functional panel system. The independent panels can be installed and treated in various distinctive patterns and arrangements to compliment interior design. The functional approach allows facilities to be acoustically upgraded without relocating utilities that are already in place, making FFPs excellent for renovation projects as well as new construction. Attractive Panel FacingsDeveloped to solve the noise control requirements of restaurants, offices, studios, theaters, music practice rooms, etc., while providing a clean, classic, cloth appearance. FFPs are fabricated from durable zinc coated steel and are finely perforate

Eckel Industries Inc. designs, fabricates and installs full and hemi-anechoic chambers to precise specifications for many industries and applications. We design chambers for government, institutional and industrial laboratories and testing facilities; and for industries including automotive, high-tech, energy, telecommunications, consumer products, audio & aircraftaerospace. Echo-Free Enclosures- 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.

SuperSoft panel linings for acoustic test facilities were developed to fill a niche in situations where a full anechoic chamber is not required. An existing or new structure can be lined with an extremely high performance acoustic panel to yield a test environment satisfactory for general product testing and noise emission.

The EW Standard Wedge is the classic design based on the original geometry established by Beranek and Sleeper at Harvard during World War II. Current E.W. Wedges incorporate the latest materials and design modifications for a wedge treatment with maximum broadband performance.

The Eckoustic Metallic Wedge represents the execution of the classic design with a perforated metal cover versus the original wire hardware cloth. Utilizing high transparancy 22 ga. perforated steel or aluminum, the metal cover is virtually acoustically transparent.

Utilizing a unique geometry, the E-Element offers a new dimension in anechoic chamber construction differing from the conventional wedge design. The E-Element is constructed of multiple parallel surfaces with tapered leading edges that alternate 90 degrees out of phase with one another. This creates a sound absorbing array which achieves cut-off with less depth of treatment than conventional "wedge" designs.[ US Patent #5.780.785 ]

Acoustic Foams, (polyurethane and melamine) offer acceptable acoustical characteristics in many applications and may be more economical than traditional treatments. Polyeurathane foam chambers must incorporate a sprinkler system because they are hazardous if combusted. Properly designed foam chambers work well in many applications.

FULL ANECHOIC CHAMBERS are engineered acoustical structures that simulate "free field" conditions, where the walls, floor or ceiling absorb 99% to 100% of the incident sound energy. These chambers are constructed with noise attenuating outer structures of masonry or modular panels and have all interior surfaces lined with anechoic wedges. (Right: Anechoic Wedges) Full anechoic chambers have working floors constructed of spring tension cable mesh or grating floor sections to support heavy test specimens above the floor wedges. These chambers are used for sound measurements in a wide variety of research and development applications such as analysis of patterns of noise for loudspeakers, microphones and electrical components, telecommunication & computer equipment, as well as clinic audiological research.
