The first objective of the acoustical design of rolling stock vehicles is the compromise between passenger comfort and the technical and economical means required to achieve it. Typically, global A-weighted sound pressure levels are used to evaluate acoustical such performance, but acoustical comfort is a complex phenomenon and it is difficult to find a single measure that fits all situations. This paper presents a novel approach to the study of one such special case: comfort experienced by passengers engaged in telephone conversations in a train. Noise inside the vehicle will affect the comfort of the telephone conversation, but we found a better measure of comfort than global dB(A) levels. Its definition, based on 1/3 octave band spectra, can be used since the beginning of the design of a new rolling stock to drive the acoustical design of passenger areas, including vestibules.
