INTRODUCTION
Cross Talk Silencers are designed tomaintain sound transmission ratings in low velocity air
transferbetweenadjoiningspaces.Theacousticbafflesprovideexcellentattenuationofspeech
andunwantednoisewhilepermittingfreshairtocirculatecontinuously.Availableforavariety
ofapplications,includingducts,walls,ceilings,anddoors.
The Cross talk attenuators are prefabricated sections of ductworkwith acoustic lining. It is
designedtoavoidnoiseradiatedfromroomorfromaductterminationwhichisconnectedvia
a main duct, to a branch duct leading to another room. Airflow is permitted whilst noise
transferislimited.
