G-SERIES Audiometric Examination Rooms

Diagnostic examination room will be Eckoustic® G-Series, Audiology Examination room manufactured by Eckel Industries. The room utilizes high performance 100 mm (4") G-Series, CamLok panel construction. Standard features will apply unless otherwise noted.

Wall and Ceiling Construction:

• Wall and ceiling panels are 100 mm (4") thick fabricated with 14 swg cold rolled steel frames and 16 swg steel outer surfaces, and framing members spaced not more than 610 mm (24") centers. The inner faces are 22 swg cold rolled steel perforated with 2.4 mm (3/32") holes on 4.0 mm (5/32") staggered centers. Inside of the outer face panels will be damped with mineral material. Panels will be filled with incombustible and inert acoustical filler having a density of not less than 1.4 kg per cubic metre (3 lb per cubic foot). Panels interlock and provide an acoustical seal using a minimum of two Cam-Lok interlocking panel connectors and a minimum of two sets of closed cell acoustic rubber seals.

Floor Construction:

• Floors are 100 mm (4") thick with 11 swg cold rolled steel walking surfaces, 14 swg cold rolled steel framing members and 16 swg bottom face sheets. Acoustical filler is high density, incombustible mineral wool fill with a minimum density of 1.4 kg per cubic metre (3 lb per cubic foot). The entire floor floats on vibration isolators and rails. Isolators are rated with a natural frequency of 6.5 Hz.

Door Construction:

• Doors are 100 mm (4") thick, of similar construction to that of the walls and ceiling. Door is flush mounted on heavy duty cam lift hinges. A double magnetic gasket sealing system and flush sill seal design assures the acoustic seal. Standard door is 927 mm x 1918 mm with an opening of 813 mm x 1873 mm (36-1/2" x 75-1/2" with an opening of 32" x 73-3/4"), and is of out-swinging design.

Window Construction:

• Double-glazed 610 mm x 762 mm (24" x 30"). Window is constructed using 6 mm (1/4") safety glass and is set in the panel using a viseo-elastic gasket.

Ventilation:

• Ventilation silencers are wall or ceiling mounted. A total of two silencers, an intake and exhaust, are provided for each room. Silencers are designed to provide up to 250 cfm each with an entrance velocity of less than 300 cfm. The system will not generate noise levels in excess of those specified by ANSI S-i 1991 standards.

Electricity and Lighting:

• Rooms are equipped with at least one double head incandescent light and one duplex receptacle. Optional additional lighting and electrical outlets are available. Electrical service runs inside the acoustic wall system whenever possible, and is connected to the outside by way of a surface exterior mounted electrical box.

Clinical Jack Panel:

• A pre-wired jack panel is provided with nine (3-wire) phone jacks, one Cinch Jones 303 and one 304 connector, and a 1" (25 mm) capped pass-through connection. The panel face is removable and will not detract from the room's acoustical performance.

Finish:

• The interior and exterior surfaces are finished with a durable commercial enamel. The standard colour is beige, however, custom colours are available.

Noise Reduction:

• The audiometric room tested in room configuration by an independent laboratory shall exhibit the following minimum characteristics when tested per ASTM E596-77. (i) data subject to change without notice (ii) Attenuation may vary slightly depending on the acoustical environment.

Optional Features:

• One Way Glass
• Special Paint Colours
• Special Oversize Windows
• Non-Standard Jack Panel
• Extra or Special Lighting
• RF Shielding Package
