"...a great noise started up in my ears, a noise that was triple or rather quadruple, compounded of a low and muffled humming, a softer murmuring as though of running water, a piercing whistle...This internal noise was so loud that it robbed me of the keen ear I had previously enjoyed and made me, not completely deaf, but hard of hearing... in spite of the throbbing in my arteries and the humming in my ears, which since that time, some thirty years ago now, have never left me for a moment...The noise was irksome, but it caused me no suffering: it was not accompanied by any chronic affliction, apart from insomnia at night..."
