I'm not an ISTP but, yes, I am very sensitive to noise, light touch, smells, lots of garish colors... I have a lot of trouble following a conversation if there is competing noise, especially if there's other conversations going. I cannot read or concentrate if there's a television on or if there is music with lyrics. If the music is light and instrumental only, I can concentrate on a book or newspaper, etc. I have been tested and found to have central auditory processing disorder, hyperacusis, and sensory integration disorder.
