Noise Influence on Quality of Communication in a Tram

This paper is about testing the intelligibility of speech during tram ride (tram model TMK 2200). Masking signal (noise) was recorded while driving in the tram. Logatomes signal was recorded in the laboratory. Test signal was produced by mixing of noise and logatomes signals. Subjects were tested in the laboratory. Measurement results analysis shows us that in realistic conditions, during the ride, the quality of communication in extremely low. We conducted additional tests with reduced noise level. The intelligibility results were much better.
