No, if you are born deaf or become deaf later in life, you are unable to hear sounds. However, some deaf people learn to "feel" sound waves, and therefore giving them some perception of sound.
Yes. Those who are deaf may not hear but they do feel the vibration of sound particularly within a defined space such as their own cranium.
A deaf dog may not be totally deaf, but merely hard of hearing. Even then it can feel sound vibrations if they are loud enough. In short a deaf dog would definitely know that it is barking.
I'm not deaf but I am an asl student who has done research on CI in class and the options of deaf people. I have discovered that deaf people don't hate CIs necessarily but feel they strip people of who they are. They believe they aren't in the hearing or deaf world and struggle with who they are. A common arguement: "deaf people aren't broken, why try to fix us."
Deaf people sense vibration in the part of the brain that other people use for hearing - which helps explain how deaf musicians can sense music, and how deaf people can enjoy concerts and other musical events. These findings suggest that the experience deaf people have when 'feeling' music is similar to the experience other people have when hearing music. The perception of the musical vibrations by the deaf is likely every bit as real as the equivalent sounds, since they are ultimately processed in the same part of the brain.
Deaf individuals may not hear sirens in the traditional sense, but they can still feel the vibrations of the sound or see emergency lights flashing. Some may also rely on specialized alert systems that use visual or tactile signals to alert them to emergencies.
Deaf people are no different than other people, except for the fact they can't hear. They don't ignore others on purpose anymore than anyone else. They are deaf and don't always know when they are being spoken to. Likewise, plenty of deaf folks believe that hearing people are ignoring them. A lot of people feel uncomfortable around deaf people since they cannot speak their language. The hearing people get in their groups and get to talking, and forget about those who cannot hear them. That is why there is even a bit of a deaf supremacy attitude in some deaf circles, because they feel excluded by those who can hear. Some take that attitude to a militant extreme, like the couple who wanted genetic engineering done to ensure they had a deaf child, and the deaf folks who consider people with cochlear implants to be sellouts.
So deaf people can communicate with other people in the society so they do not feel left out.
"Deaf" is not a derogatory term, it merely describes the condition of being unable to hear. Since some people have a reduced ability to hear but do still have some hearing, the term "hearing impaired" would be more accurate for those people. However, the term "dumb" when used to describe people who cannot speak, is insulting (since it also means stupid). So deaf is OK, but deaf and dumb is not.
Tsunamis sound like freight trains.
Deaf people can't hear so they have to have people come in to teach them sign language. It is good to know the Sign Language system so you can communicate with the deaf person and bring a smile on their face. Deaf people want to just be normal like some other kids and when kids are nice to them it makes them feel good. It is good to appreciate the good things in life than focus on the bad things.
A deaf person can feel the vibrations of the music, therefore, hearing it in a sense.
