Аннотация
To clarify the mechanical responses of the human body to airborne
vibrations, six male subjects were exposed to eight kinds of low-frequency
noise stimuli: airborne white noise, two pure tones (31.5 and 50
Hz), and five complex noises composed of pure tones. The vibrations
induced on the body surface were measured at five locations: the
forehead, the right and left anterior chest, and the right and left
anterior abdomen. It was found that the vibration acceleration levels
of both the 31.5- and 50-Hz components in the chest vibration increased
as an approximately linear function of the sound pressure levels
of each corresponding frequency component in the noise stimulus.
No clear interference was found between the 31.5- and 50-Hz components
in the chest vibration. Similar characteristics were also found in
the vibrations induced at the forehead and abdomen. These findings
suggest that within the limited range of frequency and sound pressure
level used here, the human body acts as a mechanically linear system
in response to airborne vibrations induced by complex low-frequency
noise.
