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.
