One thing more:โFrom the flimsy manner in which most modern houses are built, where every step on the stairs, and along the floors, is felt all over the house; the higher the story, the greater the vibration. It is inconceivable how much the sick suffer by having anybody overhead. In the solidly built old houses, which, fortunately, most hospitals are, the noise and shaking is comparatively trifling. But it is a serious cause of suffering, in lightly built houses, and with the irritability peculiar to some diseases. Better far put such patients at the top of the house, even with the additional fatigue of stairs, if you cannot secure the room above them being untenanted; you may otherwise bring on a state of restlessness which no opium will subdue. Do not neglect the warning, when a patient tells you that he โFeels every step above him to cross his heart.โ Remember that every noise a patient cannot see partakes of the character of suddenness to him; and I am persuaded that patients with these peculiarly irritable nerves, are positively less injured by having persons in the same room with them than overhead, or separated by only a thin compartment. Any sacrifice to secure silence for these cases is worth while, because no air, however good, no attendance, however careful, will do anything for such cases without quiet.
Note: The effect of music upon the sick has been scarcely at all noticed. In fact, its expensiveness, as it is now, makes any general application of it quite out of the question. I will only remark here, that wind instruments, including the human voice, and stringed instruments, capable of continuous sound, have generally a beneficent effectโwhile the piano-forte, with such instruments as have no continuity of sound, has just the reverse. The finest piano-forte playing will damage the sick, while an air, like โHome, sweet home,โ or โAssisa a piรจ dโun salice,โ on the most ordinary grinding organ will sensibly soothe themโand this quite independent of association.
