Electroacoustic simulations are made in order to design PA systems in railway stations or to optmise the acoustic interior of railway vehicles:
The design of PA systems include the simulation of the Speech Transmission Index (STI), Rapid Speech Transmission Index (RASTI), reverberation time or acoustic clarity for different configurations of the loudspeakers. The simulations result in an optimal acoustical design of the PA systems. Background noise levels, absorbative elements, position and type of loudspeakers are taken into account. These simulations are supported by the measurement capabilities of D2S.
Interior noise simulations result in an optimal acoustical comfort and safety for passengers.
EASE software is used to perform these simulations.
