Aim: To compare vibration exposure to noise exposure from railway traffic in terms of equal annoyance, i.e. to determine when a certain noise level is equally annoying as a corresponding vibration velocity. Method: Using questionnaire data from the TVANE research project from residential areas exposed to railway noise and vibration in a logistic regression, the dose response relationship for annoyance was estimated. By comparing the relationships between exposure and annoyance for areas both with and without significant vibration exposure the noise levels and vibration velocities that caused an equal probability of annoyance could be determined. Results: The comparison gives a continuous mapping between vibration velocity in the ground and a corresponding noise level that are equally annoying. For equivalent noise level at the facade compared to maximum weighted vibration velocity in the ground the probability of annoyance is approximately 10 % for 52 dB or 0.12 mm/s, and about 70 % for 61 dB or 0.44 mm/s.
