Meteorological Change and Hearing Funnction

Abstract

The author experienced a transitory disturbance of the hearing organ when the eye of a typhoon, a change in the natural circumstances, passed. This was caused by a slight change in the atomospheric pressure, but the greater the pressure change, the greater the disturbance. This is a transitory disturbance in the hearing organ caused by the disharmony of the ear-drum caused in its turn by the mechanical factor of the atmospheric pressure change, and will recover in due course of time in a hyperbola-curve if one remains in the same atmospheric pressure. But this disturbance in the ear is intensified by the general disturbance in the bodily function in case the atmospheric pressure is lower than half the normal one.
In the same way, a change in the atmospheric temperature causes a transitory disturbance in the hearing organ. But this is also a transitory disharmony of the'hearing function caused by the physical influence of the cold-stimulus, and will recover by degrees by the adjus, tment to the same temperature. If the cold-stimulus is too long or too intense for an organism to adapt, this disturbance will grow to lesion, or to one step t6 death from cold, and to be a partial disturbance at the ear of genera1-1iving-influence.
Furthermore, when the atmospheric pressure and temperature simultaneously become lower, if the chages are great, the effects on the hearing organ are not only phygiological as mentioned above, but are aggravated by the addition of the physical factors.
