Abstract Raising awareness about how alarm sounds are perceived and evaluated by an individual in traffic scenery is important for developing new alarm designs, as well as for improving existing ones. Bearing a positive contribution to road safety, cyclists and pedestrians especially can benefit from appropriate alarming bell and horn sounds. This work focuses on the perception of urgency for various types of bicycle bells, as well as on acoustical descriptors influencing our judgement. The conducted listening experiments reveil the recognizability of bike bells among other everyday sounds and show urgency scores for testing in both silent surrounding and with additional traffic noise background. The results support a warning sound ranking in terms of efficiency and lead to an objective urgency model formed by spectral and temoral sound parameters.
