Acoustics in subway station
This is a model of an underground station. A free field recording of an electric train (Danish 2nd generation S-train) is ‘played back’ through a line source at the rails. The announcement is played through a number of loudspeakers – the frequency response of the loudspeakers is included in the simulation. Reverberation time is around 8 seconds. Receiver is looking across the rails.
