The changes would be slower than you think actually! Inventions would get things done faster and faster income. MORE GOODS TO SELL! It also effected the transport system as well
To get someone’s attention, Deaf people might tap someone on the shoulder. Or, they might bang or tap on a table so that the vibrations cause everyone at the table to look toward the source of the vibrations. In a large group or classroom setting, flashing the lights off and on is a common way to get everyone’s attention. It’s rude to wave your hands right in front of a Deaf person’s face to get their attention. Just gently tap them on the shoulder instead. It’s ok to wave your hand, though, if you’re too far away for a shoulder tap. Here are some commons mistakes hearing people make when trying to get a Deaf person's attention. These are generally considered inappropriate or even rude.
- stomping furiously on the floor
- turning the lights on and off when you're trying to get just one person's attention, and not the entire group
- aggressively jabbing the person you want to talk to
- waving your hand right in front of the person's face

- grabbing the person's hands to force him or her to stop signing and pay attention to you (never, ever grab a Deaf person's hands--that's like someone putting their hand over the mouth of a hearing person)
