Aspirin and all of the NSAIDs give me a similar symptom -- extremely sensitive hearing (and sometimes ringing). Because of the chemical similarity, I would think the mesalamines could do it too. (But I'm not a doctor or scientist.)
I have never had that effect from Asacol or Canasa, as they are absorbed in the colon. Lialda is supposed to be absorbed there, too, as kazbern said. But maybe you're getting enough bloodstream absorption to get the effect? Probably impossible to know for sure, but sounds plausible to this layman.
