Some Deaf people are very skilled lip readers, but many are not. Only about 30% of spoken English is visible on the lips. This is because many speech sounds have identical mouth movements. For example: p and b look exactly alike on the lips.
Some Deaf speak very well and clearly; others choose not to use their voice if they think that they are difficult to understand or have problems gauging their pitch or volume. However, most Deaf people do have the physical ability to speak and therefore, they are not technically “mute”.
Deafness does not make people "dumb" in the sense of being either stupid or mute. Deaf people, understandably, find this stereotype particularly offensive The inability to hear affects neither intelligence nor the physical ability to produce sounds.
Many deaf people benefit considerably from hearing aids. Some may only be able to hear loud environmental sounds such as a fire alarm or a car horn. Still others may not benefit at all.
Deaf people lead totally different lives than other people
Most deaf individuals occupy their time just like hearing people. Of course, individual differences exist.
Deaf people cannot appreciate the arts because they can't hear music, movies, etc.
Throughout history, deaf individuals have participated in and contributed to the performing arts. Beethoven is one example. Today there are deaf artists, dance troupes, and actors. Captioning of movies and other audiovisual media is helpful for deaf citizens. As long as there is rhythm and visual image, deaf will be valued performers and patrons of the arts
Deafness is genetic. All people who are Deaf will pass Deafness onto their children
There is a type of deafness that is genetic, and some deaf people do have deaf children, however 90% of all deaf people are born to Hearing parents and will also have Hearing children.
Sign Language is bad for Deaf people because they will rely on it too much and it will make them unable to communicate with hearing people
Study after study has shown that keeping Sign Language away from Deaf people does nothing except keep all language away from Deaf people, and it can have numerous negative effects on their ability to learn.
Actually, there are at least 70 signed languages existing in the world at this time, that we know of, and all of them are incredibly distinct. American Sign Language is used in the United States, parts of Canada,and has loose relations to French Sign Language.
Deaf people don’t want to be deaf, they are hoping for some miracle cure that will make them hear
Deaf people drive cars all the time. In fact, some studies have shown that Deaf people are actually better drivers than Hearing people due to the fact that Deaf people have enhanced peripheral vision and are less distracted.
American Sign Language is spoken English conveyed through signs
Sign Language is not a manual code for the spoken language. Deaf people do not sign word-for-word to form grammatically correct sentences. Many students who Learn Signed English do not realize it is Signed English they are learning and not ASL
A signed language is just like any spoken languages, there are words and unique expressions as well as sentence structure and grammar.
Deaf and Hard of Hearing people prefer to be called Hearing Impaired
“Hearing impaired" is considered by many people to be politically incorrect, because the word impaired can sound derogatory and imply something is wrong with a person. The more accepted term is “Deaf.“
Some exceptionally language oriented people can learn it in 2-4 years. Others take at least 5-7 years. Fluency involving all the intricate nuances of the language takes a while. There is so many things that happen at the same time in ASL that to incorporate them all flawlessly requires work.
