"Seneca Letter 56.1-2
My dear Lucilius,
If you want to study, quiet is not nearly as necessary as you might think. Here I am, surrounded by all kinds of noise (my lodgings overlook a bath-house). Conjure up in your imagination all the sounds that make one hate one's ears. I hear the grunts of musclemen exercising and jerking those heavy weights around; they are working hard, or pretending to. I hear their sharp hissing when they release their pent breath. If there happens to be a lazy fellow content with a simple massage I hear the slap of hand on shoulder; you can tell whether it's hitting a flat or a hollow. If a ball-player comes up and starts calling out his score, I'm done for. Add to this the racket of a cocky bastard, a thief caught in the act, and a fellow who likes the sound of his own voice in the bath, plus those who plunge into the pool with a huge splash of water. Besides those who just have loud voices, imagine the skinny armpit-hair plucker whose cries are shrill so as to draw people's attention and never stop except when he's doing his job and making someone else shriek for him. Now add the mingled cries of the drink peddler and the sellers of sausages, pastries, and hot fare, each hawking his own wares with his own particular peal."
