The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from Expression of Emotion in Man and Animals by Charles Darwin: rendered more distinct. If a watch be placed within the mouth,
but not allowed to touch the sides, the ticking is heard much less
plainly than when held outside. In persons in whom from disease
or a cold the eustachian tube is permanently or temporarily closed,
the sense of hearing is injured; but this may be accounted for by mucus
accumulating within the tube, and the consequent exclusion of air.
We may therefore infer that the mouth is not kept open under the sense
of astonishment for the sake of hearing sounds more distinctly;
notwithstanding that most deaf people keep their mouths open.
