HOW TO ORDER
The Q-Tech range of Cross-Talk attenuators has been
designed to provide low air flow resistance whilst maintaining
a high degree of acoustic attenuation.
The CT series should be considered wherever a relief air
passage is required to penetrate a room’s acoustic barrier.
Four styles are available in both standard and high
performance configurations:-
O
CTS
- for simple wall penetration above ceiling
O
CTL
- wall to ceiling penetration
O
CTU
- ceiling to ceiling penetration
O
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
1. Select the Cross-Talk attenuator type that is required ie. CTS,
CTU etc.
2. Select high or standard performance attenuation as required.
3. When the relief air quantity is known, select from the
Air Performance Data table below, the width and depth
combination for your needs.
4. Determine final product code for ordering.
