SPD in older individuals?

How likely is it that an 18 year old with mild Tourette's and self-diagnosed OCD tendencies has an auditory SPD, or had it and never grew out of it, but learned to better deal with it?

I hear lamps, TVs, almost every other electronic, more clearly than any friends or family, and those sounds in addition to other seemingly not annoying sounds such as my sister humming or dishwasher noises continuously distract and bother me. I'm always being told to "ignore it."

Is SPD only seen in younger infants and children who haven't developed fully, or can it stick around longer?
