sound

Voices of people talking turned out to be a series of "babling" sounds to Autistic individuals. They hear people speaking clearly, yet couldn't comprehend the meaning of those sentences.

"Sensory overload" makes people stop seeing or hearing. Under these circumstances, information couldn’t enter the brain and therefore makes learning impossible.

Children with hearing impairments hear sounds like through a cell phone with poor signal, which means the connection is from time to time weak or strong, or even without connection.

If people talk too fast, autistic individuals perceive the sounds as meaningless and under this circumstances, they hear only vowels.

Put yourself in their shoes, what if you hear only part of the words, or the vowels, or specific intonations, what you would (or wouldn't) do? How many important information would be lost per day, per hour and per minute?
