Abstract
Purpose. Research efforts summarised in this study were a part of preliminary investigations to evaluate the impacts of pregnant women exposure to vibrations generated by the public transport systems. Methods. The assessment of the problem and discomfort for pregnant women on the public transport is based on a questionnaire, including questions relating to the women’s subjective feelings of well-being or discomfort when exposed to vibration during the ride in passenger cars or on public transport. In the second stage of investigations measurements were taken of vibration transmitted onto a sitting person during the tram or car ride. Results. The survey shows that when travelling on a tram, the women complained mostly of digestive or neurological disorders, during the car ride they suffered most acutely from digestive disorders, they sensed enhanced foetus movements and reported problems with the osteoarticular system. Amplitude-frequency characteristics of the investigated vehicle types reveal that vibration amplitudes registered during the ride in a motor vehicle are higher than on the tram in the analysed frequency range. Furthermore, vibration accelerations in the z-axis direction registered during the tram ride exceed the vibration discomfort threshold, particularly for the 1/3 octave bands 5 and 6.3 Hz. These are frequency ranges corresponding to resonance frequencies of vital organs in the abdominal cavity (4.5-10 Hz). Conclusions. Correlating these results with frequencies reported in literature that are associated with subjective human responses to vibration shows that pregnant women using public transport are likely to suffer from a variety of ailments caused by vibrations generated during the ride.
