Features
The Q-Tech range of Cross-Talk attenuators has been designed to provide a low resistance to air flow whilst maintaining a high degree of acoustic attenuation.
The CT series should be considered wherever a relief air passage is required to penetrate a building’s acoustic barrier.
Four styles are available in both standard and high performance configurations:-
- CTS - for simple wall penetration above ceiling
- CTL - wall to ceiling penetration
- CTU - ceiling to ceiling penetration
- CTZ - installation within the wall
Installation - General
Special care should be taken when installing CT Series Cross-Talk units to ensure maximum performance.
Consideration must be given to the sound rating of the wall or ceiling being penetrated.
It is essential that a tight airseal is achieved between the cross-talk unit and the wall/ceiling penetration.
When high performance units are used additional mass lagging of the unit casing may be required to prevent flanking transmission. This can usually be provided by building-in the cross-talk unit during the building construction phase.
Performance
The Q-Tech CT Series acoustic performance is quoted as airborne sound transmission loss as defined in AS1191:1985.
Performance data is based on Australian sourced and manufactured products.
Selection Procedure
- Select the Cross-Talk attenuator type that is required ie. CTS, CTU etc.
- Select high or standard performance attenuation as required.
- When the relief air quantity is known read from Table 1. the width and height combination for your needs.
- Determine final product code for ordering.
