An experiment was conducted to determine the subjective equivalence
of railway noise and railway-induced building vibration, and hence
the relative importance of the two stimuli. Six magnitudes of whole-body,
vertical (z-axis) vibration and six levels of noise were presented
simultaneously to each of 30 subjects in all 36 possible paired combinations.
The stimuli were reproductions of the noise and vibration recorded
inside a house during the passage of a train. The subjects were asked
to indicate, after each presentation, which of the two stimuli (noise
and vibration) they would prefer to be reduced. A seven-point scale
was employed to indicate the total annoyance produced by the two
stimuli. A subjective equivalence contour was determined from the
levels at which 50% of the subjects preferred the reduction of noise
and 50% preferred the reduction of vibration. The contour may be
described by the relation LAE = 20·3 log10VDV + 89·2, where s LAE
is the sound exposure level and VDV is the vibration dose value.
This relation may be used to determine whether a reduction of noise
or a reduction of vibration would be more beneficial to residents
near railways. The total annoyance due to simultaneous noise and
vibration was shown to depend on the magnitude of both stimuli.
