Abstract
Subway fan and vent shafts can be significant sources of noise impact to both the adjacent community and to patrons in the subway stations. For fan shafts, the transmission of airborne noise through the shafts and surface openings to adjacent buildings and the transmission of noise through the subways to station platform are intrusive. For vent shafts airborne noise transmissed from trains passing by in the subway below to surface openings can be intrusive. The primary methods available for the reduction of fan and train noise propagated out shaft openings and fan noise propagated into the stations are (1) the use of acoustical absorption material on the interior surfaces of fan rooms, fan and vent shafts and tunnel walls and ceilings, (2) the use of sound attenuators [silencers] attached to the fans, (3) the use of specially constructed splitters in the fan and vent shafts or fan rooms, and (4) the use of acoustical louvers.
