Hearing people can do at least two things at once. Hearing impaired people can usually only do one thing at a time. They can't read and listen, work and listen, take notes and listen, etc. Instead, they must stop everything and focus on communication. In the hustle and bustle of today's world that is a distinct limitation.
Passion too is affected by hearing loss.
Take the case of the couple who historically have had sexual intercourse in a dark room. The intimate sharing in those circumstances which elevate the sex act to a higher level of love begins to disappear. Something precious is missing and the quality of the marriage can suffer. Turn on the lights, you say. But habit dies hard.
