 Cross Talk Attenuator  A to Z Products
 Introduction
 
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.

COSMOS cross talk attenuator models CTA‐Z, CTA‐L and CTA‐U are used as air transfer attenuators between adjoining areas where as the acoustic integrity of a common partition or ceiling need to be maintained.
 
  Construction
 
Casings are manufactured from galvanized sheet metal 20 gauge. The acoustically engineered internal baffles are lined with open cell elastomeric nitrile foam rubber, fiber free, super silent and microban resistance and provide excellent noise reduction.
 
  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.
 
  Features & Benefits
 
20 gauge galvanized sheet metal casing construction.
Open cell elastomeric nitrile foam rubber, fiber free, super silent and micro ban resistance material as acoustic media.
Permits air transfer while attenuating unwanted noise.
Provides privacy by minimizing speech transmission.
Wide range of sizes and designs available to suit variety of applications.
 
  Applications
 
Provide continuous air ventilation and control of unwanted sound between adjacent spaces:
 
CTA‐L: Reduce unwanted noise entering a space from a common plenum, shaft or corridor.
CTA‐Z: Minimize sound transmission through a wall or door.
CTA‐U: Prevent noise transfer between rooms through the false ceiling.
