This is a title of a booklet produced by The Geneva Centre (of Toronto, Canada) that includes many quotes of people with ASDs of their own sensory experiences. I found this book helped tremendously to develop a sense of just how differently we all experience this world through our basic five senses. My son, like many people with ASDs has difficulty dialing down or filtering background noises. To gain an idea of just how that might "feel" - I would sit in a quiet room and deliberately try to hear every single little buzz, whir, click, hum and then imagine that I could never find a spot to escape these sounds. Afterward, many of my son's expressions of frustration seemed to be more logical. Over time, I learned which types of sounds bothered him the most and was sometimes able to peg them as the causes of difficult behaviors and to reduce his frustration by selectively removing the ones I could from his environment. It also helped my son to understand for himself that this was an issue for himself and he did find many ways to cope himself in environments with noises that were inherently irritating to him. He likes headphones (and thankfully this has become more and more a socially acceptable thing to do).
He had similar issues with smells. One quote from the book (not him but someone with a similar experience to his): "I did not like the smell of fresh grass (as a child). Fresh grass has really too much smell for me to like going on the grass." Somedays my son would tantrum just going out the door - those days... after a rain, after we had just mowed the lawn... Once he knew how to tell us which smells bothered him, it got easier to respect his sensitivities.
