In terms of sound, people with ASD may only hear sounds in one ear, they may not acknowledge particular sounds, or they might even enjoy going to crowded places. However, people with ASD might hear sounds that are magnified and become distorted, or they could be extremely sensitive to sounds and can often hear conversations in the distance better than those without ASD.
When it comes to touch, people with ASD may experience more pain and discomfort and often only like certain types of clothing and textures. Many people with ASD do not like to be touched and therefore are extremely more sensitive to it.
Research has shown that people with ASD can handle spicy foods better than people without and can often eat almost everything in sight, even non edible foods, this is called pica. The other extreme could be those with ASD find some foods and flavors to be too strong and overpowering or even some food textures could cause discomfort.
Last is smell. Some people with ASD have no sense of smell and do not notice strong odors, within others, some smells can be extremely intense and overpowering.
