Cross Talk Sound Attenuators
Cross Talk Sound Attenuators
Standard Model : CLE
Cross Talk Silencers are designed to maintain sound transmission ratings in low velocity air transfer between adjoining spaces. The acoustic baffles provide excellent attenuation of speech and unwanted noise while permitting fresh air to circulate continuously. Available for a variety of applications, including ducts, walls, ceilings, and doors.
Product Description
Cross Talk Silencers are designed to maintain sound transmission ratings in low velocity air transfer between adjoining spaces. The acoustic baffles provide excellent attenuation of speech and unwanted noise while permitting fresh air to circulate continuously. Available for a variety of applications, including ducts, walls, ceilings, and doors.
The Cross talk attenuators are prefabricated sections of ductwork with acoustic lining. It is designed to avoid noise radiated from room or from a duct termination which is connected via a main duct, to a branch duct leading to another room. Airflow is permitted whilst noise transfer is limited. COSMOS Cross talk attenuators are designed to supply continuous ventilation between adjacent spaces or rooms while maintaining sound transmission ratings of the common partition.
Standard Construction
Casings are manufactured from galvanized sheet metal 20 gauge. The acoustically engineered internal baffles are lined with high density infill acoustic material which provides a high degree acoustic attenuation.
When installed in the sidewall near the ceiling, linear grille provides horizontal pattern above the occupied zone. Core deflections of 15 and 30 degree direct the air path upward to overcome the drop effect resulting from cool supply air. Use of deflected cores also improves sight tightness of the grille face.
CTA‐Z Cross Talk Attenuator
COSMOS CTA-Z Cross Talk silencers are designed for low velocity transfer air applications through walls or doors. This low velocity configuration provides the highest insertion loss levels across the full range of frequencies.
CTA‐L Cross Talk Attenuator
COSMOS CTA-L Cross Talk silencers are designed for low velocity transfer air applications where multiple installations involve a common shaft. This low velocity configuration provides the highest insertion loss levels across the full range of frequencies.
CTA‐U Cross Talk Attenuator
COSMOS CTA-U Cross Talk silencers are designed for low velocity transfer air applications in false ceilings. This low velocity configuration provides the highest insertion loss levels across the full range of frequencies.
