As someone with misophonia[0] this would be an unbearable and unsettling punishment. Hearing other people eating is like being stuck in an elevator after lunch, when someone drops their guts. But, even quiet chatter or tv is enough to mask the sound.
To say nothing of the boredom of 15 minutes of a silence.

> Misophonia (or selective sound sensitivity syndrome, sound-rage) is a disorder of decreased tolerance to specific sounds or their associated stimuli, or cues. These cues, known as "triggers", are experienced as unpleasant or distressing and tend to evoke strong negative emotional, physiological, and behavioral responses that are not seen in most other people.
